Configure BFD.
Bidirectional Forwarding Detection for BFD is a universal mechanism used to detect communication faults between forwarding engines. To be specific, BFD detects the connectivity of a data protocol on the same path between two systems. The path can be a physical link, a logical link, or a tunnel. BFD can be regarded as a service provided by the system. The upper-layer applications provide BFD parameters such as detection address and detection time. BFD creates, deletes, or modifies BFD sessions based on these information and informs the upperlayer applications of the session status. The upperlayer applications then determine whether to take actions as the BFD session status changes.

Configure VRRP.
Virtual Router Redundancy Protocol for VRRP is a fault-tolerant protocol. By combining a group of routers on a LAN into a virtual router, VRRP can switch the services to other routers through certain mechanisms when the next hop router fails. This ensures continuity and reliability in communication. Compared with other methods, VRRP is easy to configure and convenient to manage. The advantage of VRRP is that a default route with higher reliability can be obtained without changing the networking. Also, no dynamic routing protocols or routing discovery protocols need to be configured on the host.

4 Basic Concepts
4.1 Tunnel Overview Different tunnel technologies are used in various scenarios and different protocols are used to transparently transmit data packets.
4.1.1 Introduction to the Tunnel The U2000 supports tunnels using MPLS and IP.
MPLS Tunnel MPLS acts as a transmission technology used for transparent packet transmission. The MPLS tunnel is the tunnel defined in the MPLS protocol. Independent of services, the MPLS tunnel implements end-to-end transmission and carries service-related PWs. Figure 4-1 shows how the MPLS tunnel transmits services. Figure 4-1 MPLS tunnel on the MPLS network

PW
The MPLS tunnel provides only an end-to-end channel and does not care which service is encapsulated in the PW it carries. Data packets are first encapsulated in the PW, which is attached with an MPLS label and sent to the MPLS tunnel for transmission. At the sink end, data packets are recovered by retaining the original service features. In the tunnel, the intermediate nodes are called transit nodes. A tunnel consists of the ingress, egress, and transit nodes. Based on signaling types, MPLS tunnels can be classified into three types, that is, the static tunnel, the static CR (Constraint-based Routed) tunnel, RSVP TE (Resource Reservation Protocol-Traffic Engineering) tunnel, and LDP (Label Distribution Protocol) tunnel. These four types of tunnels are different and the details are as follows: l
Static: Labels for static tunnels are distributed manually. No signaling protocol is used and no control packet is exchanged.
l
Static CR tunnel: A static CR tunnel is created with certain constraints. The mechanism for creating and managing those constraints is CR. Different from a static tunnel that requires only routing information, creating a CR tunnel has other configurations, such as the bandwidth, route, and QoS parameters.

l
LDP: You only need to specify the ingress and egress nodes for an LDP tunnel. Then the LDP protocol sets up a route for the tunnel. An LDP tunnel functions on the network that supports the MPLS domain and therefore is more flexible.
l
RSVP TE tunnel: You need to specify only the ingress and egress nodes for an RSVP TE tunnel. The MPLS protocol automatically calculates a route for the tunnel. In addition, you can specify constraint nodes to plan a specific route for the tunnel. You can configure FRR protection and the QoS function for an RSVP TE tunnel. Therefore, an RSVP tunnel is more flexible and safer than an LDP tunnel.
IP Tunnel If an ATM or CES emulation service that travels through an IP network is required, the NE can use the IP tunnel to carry the service. Figure 4-2 shows the protocol stack model of the ATM service. In the case of the IP tunnel, the situation is similar to that where the IP header replaces the MPLS external label (MPLS tunnel label) to establish a tunnel on the IP network. An ATM emulation service can be provided between NE A and NE B, even though the IP network between NE A and NE B does not support MPLS. Figure 4-2 ATM PWE3 over IP tunnel ATM switch

4.1.2 Standards and Protocols Compliance of the Tunnel This topic describes the standards compliance and the two protocols that the tunneling technology uses. The protocols are MPLS-LDP and MPLS-RSVP.Currently, the Hybrid MSTP equipment does not support LDP and RSVP TE.
MPLS-RSVP Protocol Multi-protocol label switch resource reservation protocol (MPLS-RSVP) supports MPLS label distribution. When transmitting a label binding message, MPLS-RSVP carries resource reservation information and acts as a signaling protocol to create, delete, or modify tunnels on the MPLS network. Basic Concepts of MPLS-RSVP MPLS-RSVP is a notification mechanism of resource reservation on the network, reserving the bandwidth on the control plane. MPLS-RSVP also acts as a label distribution protocol to set up LSPs on the MPLS network. Issue 03 (2014-05-15)

iManager U2000 Unified Network Management System Operation Guide for IP Service Management
4 Basic Concepts
For details about MPLS-RSVP extension, see RFC 3209. Resource Reservation Style The LSP established using MPLS-RSVP is of a certain reservation style. When an RSVP session is established, the receive end determines which reservation style to be used, and therefore determines which LSP to be used. l
Fixed-filter (FF) style: When this style is used, resources are reserved for each transmit end. Hence, transmit ends in the same session cannot share the resources with each other.
l
Shared-explicit (SE) style: When this style is used, resources are reserved for all transmit ends in the same session. Hence, transmit ends can share the resources. NOTE
Currently, OptiX equipment supports only the SE resource reservation style.
MPLS-RSVP Message Type MPLS-RSVP uses the following types of messages: l
Path message: The transmit end sends this type of message in the transmission direction of data packets. The path status is saved on all the nodes along the trail.
l
Resv message: The receive end sends this type of message in the reverse transmission direction of data packets. The resource reservation is requested, and the reservation status is created and maintained on all the nodes along the trail.
Parameters of the MPLS-RSVP State Timer The parameters of the MPLS-RSVP state timer include the refreshing period of the Path or Resv message, and the multiple of the path state block (PSB) timeout and reservation state block (RSB) timeout. When an LSP is being created, the transmit end adds the LABEL_REQUEST object to the Path message. When the receive end receives the Path message with the LABEL_REQUEST object, it distributes one label and adds the label to the LABEL object of the Resv message. The LABEL_REQUEST object is saved in the PSB of the upstream node, and the LABEL object is saved in the RSB of the downstream node. When the message indicating that the number of message refreshing times exceeds the multiple of the PSB or RSB timeout is not continuously received, the corresponding state in the PSB or RSB is deleted. Assume that there is a resource reservation request, which does not pass the access control on some nodes. In some cases, this request cannot be immediately deleted, but it cannot stop other requests from using its reserved resources. In this case, the node enters the blockade state, and the blockade state block (BSB) is generated on the node of the downstream. When the message indicating that the number of message refreshing times exceeds the multiple of the PSB or RSB timeout is continuously received, the corresponding state in the BSB is deleted.
MPLS-LDP Protocol The multi-protocol label switch label distribution protocol (MPLS-LDP) is used for label switched routers (LSR) to distribute labels on the network. MPLS-LDP Peers MPLS-LDP peers are two NEs that use MPLS-LDP to exchange the label mapping relationship based on an LDP session. Issue 03 (2014-05-15)

4 Basic Concepts
MPLS-LDP Session An MPLS-LDP session is used to exchange label mapping and releasing messages between different NEs. MPLS-LDP sessions are classified into the following types: l
Local MPLS-LDP session: The two NEs used to set up the session are directly connected.
l
Remote MPLS-LDP session: The two NEs used to set up the session are not directly connected.
MPLS-LDP Message Types MPLS-LDP messages are classified into the following types: l
Discovery message: This type of message is used to notify and maintain the existence of the equipment on the network.
l
Session message: This type of message is used to set up, maintain, and end the session between MPLS-LDP peers.
l
Advertisement message: This type of message is used to create, change, and delete the label mapping.
l
Notification message: This type of message is used to provide suggestion messages and error notifications.
Standards and Protocols Compliance The tunneling technology is compliant with the following standards and protocols: l

4.1.3 Principles Multi-protocol label switching (MPLS) is a tunneling technology, providing a routing and switching platform that integrates the switching and forwarding technologies of labels and network-layer routing technologies. In the MPLS architecture, the control plane is connectionless and uses the powerful and flexible routing function of the IP network to meet new network application requirements; the data plane is connection-oriented and uses short and fixed-length labels to encapsulate packets for implementation of fast forwarding.

Forwarding equivalence class (FEC) is a class of packets that are forwarded in the same way on an MPLS network. Label A label is a short and length-fixed identifier. The label identifies the FEC that a packet belongs to and is applicable only to the MPLS domain. One FEC may involve multiple labels but one label can indicate only one FEC. LDP Label distribution protocol (LDP) is the control protocol for MPLS. Similar to the signaling protocol of a traditional network, the LDP is responsible for classifying FECs, distributing labels, and creating and maintaining LSPs or PWs. MPLS can use the following label distribution protocols: l
Protocols exclusive for label distribution, such as LDP.
l
Existing protocols extended to support label distribution, such as RSVP-TE.
l
Currently, the Hybrid MSTP equipment does not support LDP and RSVP TE.
LSP On an MPLS network, the trail that an FEC traverses is called label switched path (LSP), a unidirectional path from the ingress node to the egress node. LSPs are classified into static LSPs and dynamic LSPs. Static LSPs must be manually configured and dynamic LSPs are dynamically generated using LDP. LSR Label switching routers (LSRs) are basic elements in an MPLS domain. All LSRs support MPLS. Each node on an LSP is an LSR. An edge LSR (LER) resides at the edge of an MPLS domain and connects to other user networks. The core LSR resides in the center of an MPLS domain. Packets travel along an LSP and enter an MPLS domain. The incoming LER is the ingress node, the outgoing LER is the egress node, and the intermediate nodes are transit nodes. An LSR consists of the control unit and forwarding unit. l
The control unit distributes labels, selects routes, creates label forwarding tables, and sets up or remove LSPs.
l
The forwarding unit forwards received packets according to the label forwarding tables.
NHLFE Next hop label forwarding entry (NHLFE) describes the operations that an LSR performs on labels, including push, swap, and pop.

The creation process is as follows: 1.
The ingress node uses the encapsulation protocol to calculate a path destined to the egress node and sends a label request packet to the egress node along the trail.
2.
After receiving the label request packet, the transit node forwards the packet to the egress node.
3.
After receiving the label request packet, the egress node assigns an ingress label to the tunnel, sets up a forwarding entry, and sends a label mapping packet to the ingress node.
4.
After receiving the label mapping packet, the transit node assigns an ingress label to the tunnel, sets up a forwarding entry, and forwards the label mapping packet to the ingress node.
5.
After receiving the label mapping packet, the ingress node sets up a forwarding entry. The tunnel is created successfully between the ingress node and egress node.

information, you can create a label mapping table for each NE. Each LSR receives packets and performs the following NHLFE operations on the packets after the label mapping table is created: l
Push: The ingress node receives packets and checks for the FEC that the packets belong to. Then the ingress node adds labels to the packets and transmits the encapsulated MPLS packets to the next hop through the outbound interface.
l
Swap: A transit node uses the forwarding unit to forward the packets according to the packet labels and the label forwarding table. A transit node does not perform any Layer 3 operation on the packets.
l
Pop: The egress node strips labels from the packets and forwards the packets.
4.1.3.3 Tunnel Protection Group Automatic protection switching (APS) of the MPLS tunnel is a network protection mechanism. The protection MPLS tunnel protects the services transmitted in the working MPLS tunnel. If the working MPLS tunnel is not functioning properly, the services are switched to the protection MPLS tunnel. In this way, the services transmitted in the working tunnel are protected. OptiX PTN equipment supports 1+1 and 1:1 APS protection of the MPLS tunnel.
Basic Information APS The automatic protection switching (APS) protocol is used to coordinate the actions of the source and sink in bidirectional protection switching. Using the APS protocol, the source and sink cooperate with each other to perform functions such as protection switching, switching delay, and WTR. According to ITU-T Y.1720, the source and sink both need to select channels in the APS. In this case, the APS protocol is required for coordination. In the case of bidirectional protection switching, the APS protocol needs to be used regardless of the revertive mode. The APS protocol is always transmitted over the protection tunnel. Then the equipment at either end knows that the tunnel from which the APS protocol is received is the protection tunnel of the peer end and therefore determines whether the configurations of the working and protection tunnels are consistent between both ends. Switching Mode MPLS APS provides two switching modes, that is, single-ended switching and dual-ended switching. The PTN chassis-shaped equipment supports only dual-ended switchover. The PTN case-shaped equipment supports single-ended and dual-ended switchover. In the case of single-ended switching, when one end detects a fault, it only performs switching at the local end and does not instruct the peer end to perform any switching. In the case of dual-ended switching, when one end detects a fault, it performs switching at the local end and also instructs the peer end to perform switching. single-ended switching does not require the APS protocol for negotiation. It features rapid and stable switching. dual-ended switching ensures that the services are transmitted in a consistent channel, which facilitates service management. Revertive Mode Issue 03 (2014-05-15)

iManager U2000 Unified Network Management System Operation Guide for IP Service Management
4 Basic Concepts
The MPLS APS function supports two revertive modes, that is, revertive mode and non-revertive mode. In the non-revertive mode, services are not switched from the protection tunnel to the working tunnel even when the working tunnel is restored to the normal state. In the revertive mode, services are switched from the protection tunnel to the original working tunnel if the working tunnel is restored to the normal state within the WTR time. WTR Time The WTR time refers to the period from the time the original working tunnel is restored to the time the services are switched from the protection tunnel to the original working tunnel. In some scenarios, the status of the working tunnel is unstable. Setting the WTR time helps to prevent frequent switching of services between the working and protection tunnels. The WTR time on PTN devices is 300 seconds by default. The WTR time on routers is 720 seconds by default. Hold-off Time The hold-off time refers to the period from the time the equipment detects a fault to the time the switching operation is performed. When the equipment is configured with MPLS APS protection and other protection, setting the hold-off time can ensure that other protection switching operations are performed first. By default, the hold-off time of the equipment is 0s. 1+1 Protection For protection groups of the 1+1 protection type, the source end sends and receives services, and the sink end selectively receives services. If the working tunnel fails, the protection tunnel takes over to receive services and implement service switchover. 1:1 Protection For protection groups of the 1:1 protection type, services are transmitted on the working tunnel. If the working tunnel fails, the protection tunnel takes over to transmit services. The source end sends services and the sink end receives services.
Application of the Tunnel Protection The MPLS tunnels of the same type are created in one tunnel protection group. In this way, 1 +1 or 1:1 protection is provided to these MPLS tunnels. If the working MPLS tunnel fails, the tunnel protection group ensures that services can still properly run. Using the U2000, you can configure 1+1 or 1:1 protection for MPLS tunnels that carry important services. Figure 4-5 shows the protection principle for unicast tunnels.

4.1.3.4 Application of the Tunnel An MPLS tunnel acts as the carrier of PWs to transmit service packets. The MPLS tunnel can carry various services, such as CES services, ATM/IMA services, Ethernet services and protocol packets. Currently, the Hybrid MSTP equipment supports only the Ethernet service. The MPLS tunnel is mainly used for transparent transmission of point-to-point data packets.
Transparent Transmission of Point-to-Point Data Packets A tunnel provides a point-to-point path for services such as EPL services. In this way, PEs on a PSN network can transparently transmit services. Figure 4-6 shows how point-to-point data packets are transparently transmitted on a network.

Figure 4-6 Transparent transmission of point-to-point data packets
An edge node on the network receives services from Node B and transmits the services to the RNC connected to another PE. In this case, a point-to-point MPLS tunnel can be used.The usage scenarios of different tunnels are as follows: l
When an IP tunnel transmits services, the services can be transparently transmitted on a third-party IP network. Therefore, IP tunnels are used mainly when the services that the PTN equipment transmits need to be transparently transmitted on a third-party IP network.
l
When a static CR tunnel transmits services, the services can be transparently transmitted on the entire MPLS network. Therefore, static CR tunnels are used mainly when high QoS is not required and the routes are specified.
l
When an RSVP TE tunnel transmits services, the services can be transparently transmitted on the entire RSVP TE network. RSVP TE tunnels are used when high QoS and resource usage are required on the network.
l
When an LDP tunnel transmits services, the services can be transparently transmitted on the entire MPLS network. LDP tunnels are widely used for MPLS VPNs. To prevent traffic congestion on some nodes of a VPN, you can configure LDP over RSVP. That is, the LSP of an LDP tunnel traverses the RSVP TE domain and therefore the LDP tunnel can transmit VPN services.
When all the preceding tunnels traverse the third-party equipment, you can configure the thirdparty equipment as a virtual node to ensure that the tunnels are created properly. Currently, the Hybrid MSTP equipment supports only the static CR tunnel.the NG WDM equipment supports only the static CR tunnel.

An MPLS protection ring has the following advantages: l
Saves tunnel resources. Only working tunnels need to be configured for services while protection tunnels are not required.
l
Reduces the consumption of network element (NE) and link bandwidths. An NE on an MPLS protection ring is required to use only two operation, administration and maintenance (OAM) instances and one automatic protection switching (APS) instance. The quantities of OAM instances and APS instances are irrelevant to the number of services.
l
Simplifies the configuration process. Services are not affected as long as protection ring data is configured on NEs added to an MPLS protection ring.
l
Improves service reliability. Intersectant protection rings can be used to protect services in some scenarios where multiple NEs fail.

4.2.3 Principle Description for an MPLS Protection Ring The Shared Protection Ring (SPRing) is a protection switchover mechanism defined in the ITUT G.8132 standard. A group of nodes constitute a closed loop and each node is connected to two adjacent nodes using a bidirectional channel. Ring network protection involves two rings that provide protection for each other and are in opposite directions. Both of the two rings provide working and protection channels and redundant bandwidth or network devices. In this way, services can be automatically restored after the network does not function properly or deteriorates.
4.2.3.1 Basic Concepts This topic describes basic concepts related to a Multiprotocol Label Switching (MPLS) protection ring. At present, the U2000supports only the wrapping mode. Ring Node A ring node is a logic concept defined in the G.8132 standard. An NE ID uniquely identifies an NE in a ring protection group. Multiple ring protection groups can be configured on a tangent or intersectant NE; therefore, an NE can be assigned different NE IDs for different ring protection groups. The solid ring IDs range from 1 to 127 and the virtual intersecting node IDs range from 128 to 255. East Interface/West Interface Each node in a ring uses two interfaces to receive and send data. The two interfaces are considered the east interface and west interface based on the role in the ring topology view. The east interface is used to send packets transmitted in a counter-clockwise direction and receive packets transmitted in a clockwise direction. The west interface is used to receive packets transmitted in a counter-clockwise direction and send packets transmitted in a clockwise direction. Ring Channel A ring protection group consists of four logical rings: working tunnel ring in a clockwise direction, protection tunnel ring in a clockwise direction, working tunnel ring in a counterclockwise direction, and protection tunnel ring in a counter-clockwise direction. Four ring labels are provided to differentiate these tunnel rings. Each ring label has the same value on all NEs in a ring. The eastbound protection channel protects westbound working tunnels and the westbound protection channel protects eastbound working tunnels. Intersecting node Intersecting node: An intersecting node consists of two physical nodes and contains information about the source and destination rings. As shown in the following figure, ring 1 and ring 2 are intersected, the configured intersecting nodes are C and D. The intersecting node C has the information about intersecting node D and the information about the source ring (ring 1) and destination ring (ring 2). The virtual intersecting node D has the information about intersecting node C and the information about the source ring (ring 2) and destination ring (ring 1). Every ring uses the virtual intersecting node as a drop node to create a ring path. When two rings intersect, only two intersecting nodes are allowed. If multiple physical intersecting nodes exist, the two nodes that have the longest distance between each other are used as intersecting nodes. If one ring intersects with multiple rings, multiple intersecting nodes need to be configured. Intersecting node information must be configured for all nodes on a ring to ensure the integrity of the ring topology. Issue 03 (2014-05-15)

4.2.3.2 MPLS Protection Ring and Tunnels An MPLS protection ring is located at the server layer but a tunnel is located at the service layer. After service traffic on a tunnel is switched to an MPLS protection ring, a ring label needs to be added to the packets so that the traffic is forwarded based on the ring label, without the need to exchange the tunnel label. After the traffic leaves the ring, the ring label is removed and the tunnel label needs to be exchanged. As shown in the following figure, the tunnel passes through nodes A, B, C, and D. Tunnel configurations are performed only on nodes A and D instead of B and C.

4.3 PWE3 Overview In a packet switched network (PSN), PWE3 is a Layer 2 service bearing technology that emulates as faithfully as possible the basic behaviors and characteristics of ATM services, Ethernet services, low-rate CES circuit services, and other services. Such a technology can interconnect the traditional network and PSN to share resources and expand the network. The MSTP equipment supports only CES and Ethernet services.

4.3.1 Introduction to the PWE3 PWE3 is a point-to-point Layer 2 VPN (Virtual Private Network) technology. This technology adds new signaling, reduces signaling costs, regulates the auto-negotiation mode of multiple hops, and achieves flexible networking.
Definition PWE3 is a Layer 2 service bearing technology that emulates as faithfully as possible the basic behaviors and characteristics of services such as ATM, frame relay, Ethernet, low-rate CES circuit, and synchronous optical network (SONET)/synchronous digital hierarchy (SDH) on a PSN.
Objectives With development of the IP network, the IP network has great compatibility and capabilities for expansion, upgrade, and interworking. The traditional communication network, which has poor capabilities for expansion, upgrade, and interworking, is restricted by the transmission mode and service type. In addition, newly built networks support a few services and are unsuitable for interworking management. Hence, during the upgrade and expansion of traditional communication networks, you should consider whether to build duplicated networks or use existing or common network resources. PWE3 is a solution that combines traditional communication networks with the existing packet networks. The PWE3 protocol reduces packet exchanges, avoids repeated PW creation and deletion caused by network instabilities. PWE3 has some MPLS L2VPN advantages and can be used to interconnect traditional networks with PSNs to implement resource sharing and network expansion.
4.3.2 Reference Standards and Protocols of the PWE3 This topic describes the standards compliance and protocols for various technologies used in PWE3. The reference documents of this feature are as follows.

4.3.3.1 PWE3 Basic Principle This topic describes the implementation principle for PWE3 to carry various Layer 2 services on the customer edge (CE) side.
Basic Concepts of PWE3 l
UPE: ultimate PE. The UPE functions as an edge device on the backbone network that is connected to the user edge devices on a VPN network. Generally, an AC directly accesses the first or last PW on several PEs.
l
SPE: switching point PE. The SPE functions as a device responsible for PW switching and PW label forwarding inside the backbone network.
l
AS: autonomous system. An AS is a collection of routers that are under the control of one entity and have the same internal routing policy.
Basic Transmission Components of PWE3 As shown in Figure 4-7, the basic transmission components of the PWE3 network are as follows: Issue 03 (2014-05-15)

The VPN1 packet flow from CE1 to CE3 is used as an example. The basic data flow is as follows: l
Layer 2 packets are sent to CE1 first, and the packets gain access to PE1 through the link.
l
After PE1 receives the packets, the forwarder selects the PWs for forwarding packets.
l
PE1 generates two MPLS labels (a private network label and a public network label) according to the PW forwarding entries. The private network label is used to identify the PW, and the public network label is used for a service to traverse over the tunnel to PE2.
l
The Layer 2 packets reach PE2 through the public network. Then the system prompts private network labels (on the P equipment, public network labels are prompted in the last hop but one).
l
The forwarder of PE2 selects the link for forwarding packets and forwards the Layer 2 packets to CE3.
PWE3 Network Mode The PWE3 network can work in single-hop mode or multi-hop mode. l
Single-hop PWE3 network Single-hop PW indicates that only one PW is available between UPEs, and the switching of the internal label is not required. Figure 4-8 shows the typical network topology of the single-hop PW.

Multi-hop PWE3 network in LDP mode In most cases, the single-hop PW can meet requirements. In the following three scenarios, however, the single-hop PW cannot meet requirements and the multi-hop PW needs to be used: – Two PEs are not in the same AS domain. In addition, the signaling connection or tunnel between the two PEs cannot be constructed. – The signaling types on the two PEs are different. For example, one end runs LDP and the other end runs RSVP. – The access equipment can run MPLS, but it cannot construct a large number of LDP sessions. In this case, the user facing provider equipment (UFPE) is used as the UPE and the high-performance SPE is used as the switching node (similar to the signaling reflector) of the LDP sessions. – The multi-hop PW indicates that multiple PWs are available between UPEs. The forwarding mechanisms of the UPE are the same in the case of multi-hop forwarding and single-hop forwarding. In the case of multi-hop forwarding, the switching of the PW label must be performed on the SPE. Figure 4-9 shows the typical network topology of the multi-hop PW using LDP as the signaling protocol.

Static PW The static PW does not use the signaling protocol for parameter negotiation. The information required by the static PW is manually specified through commands, and the data is transmitted between PEs through the tunnel.
Dynamic PW The dynamic PW is a PW constructed through signaling protocol. The UPE switches the PW label through the LDP and bundles the corresponding CE through PW ID. After the tunnel that connects two PEs is successfully constructed and the label switching and bundling are complete, if the link of the two PEs is up, a PW is constructed. The message packets of the dynamic PW consist of: l
Request: Requests for label allocation from the peer end.
l
Mapping: Notifies the peer end of the label at the local end and determines whether to contain the status message according to the default signaling action. (The default Martini mode does not support the status message.)
l
Notification: Notifies status to negotiate the PW status, reducing the number of packets for interaction.
l
Withdraw: Contains the relevant label and status to notify the peer end to cancel the label.
l
Release: As a response to the Withdraw packet, notifies the peer end to send the Withdraw packet to cancel the label.
Extension of the PWE3 Control Plane l
Signaling extension The Notification mode is added to the LDP signaling. In this manner, only status is notified and the signaling is not cleared unless the configuration is deleted or the signaling protocol is interrupted. This mode reduces packet interaction and signaling overheads and is compatible with the original LDP and Martini modes.
l
Multi-hop extension The multi-hop PW function is added, which extends the network mode. – The multi-hop PW lowers the requirement on the count of LDP connections of the access equipment, that is, lowers the overheads of the LDP session of the access nodes. – Multi-hop access nodes meet the PW convergence requirement, which facilitates the network flexibility and is applicable to different levels (access, convergence, and core).
l
CES interface extension More telecommunication low-speed CES interfaces are supported. The functions of CES packet sequencing, and clock extraction and synchronization are added using the control word (CW) and the forwarding plane Real-time Transport Protocol (RTP). The advantages of the low-speed CES interfaces are as follows: – The encapsulation type is added to support the encapsulation of low-speed CESs. – The PSTN, TV, and data networks can be integrated.

– It is a mode used to substitute the traditional DDN service. Currently, the MSTP equipment does not support this interface. l
Other extension Other extension on the control plane is as follows: – The negotiation mechanism of the fragmentation capability is added to the control plane. – The PW continuity check, such as virtual circuit connectivity verification (VCCV) and PW operation administration and maintenance (OAM), is added, improving the convergence capability and reliability of the network.

4.3.3.2 VCCV Virtual circuit connectivity verification (VCCV) is a technology that is used to verify and diagnose the connectivity of a PW forwarding trail. VCCV is an end-to-end PW fault detection and diagnosis mechanism. That is, the VCCV is the control channel in which connectivity verification messages are sent between the PW ingress and egress nodes. The objective of VCCV is to verify and further diagnose the connectivity of the PW forwarding trail. VCCV ping is a tool that helps you to manually check the connectivity of the virtual circuit. VCCV ping is achieved based on extended LSP ping. VCCV defines a series of messages exchanged between PEs to verify the PW connectivity. To ensure that the VCCV packets and data packets in the PW pass through the same trail, the VCCV packets and PW packets must have the same encapsulation mode and pass through the same tunnel. VCCV Traceroute is a tool that helps you to manually check the connectivity of the virtual circuit. VCCV Traceroute supports detection of transit NEs between the source and sink NEs to obtain the packet loss ratio and delay between the source NE and each of the transit NE and determine the fault point.
4.3.3.3 Static and Dynamic Hybrid Multi-Hop PW This topic describes static and dynamic hybrid multi-hop PWs. Hybrid multi-hop PW refers to a PW with one end being a static PW and the other end being a dynamic PW (LDP). Either the static or dynamic PW can have multiple hops. The static and dynamic PWs cannot have multiple hops in interleaved mode. As shown in Figure 4-10, the PW between UPE1 and the SPE is a dynamic PW and that between UPE2 and the SPE is a static PW.

4.3.3.5 ATM Cell Transparent Transmission This topic describes the ATM cell transparent transmission technology.
Definition ATM cell transparent transmission is a technology that is used to bear ATM cells in the PWE3 virtual circuit.
Objective ATM cell transparent transmission uses the PSN to connect traditional ATM network resources and emulates traditional ATM services on the PSN. In this case, traditional ATM network services are emulated to the maximum when traversing the PSN. Therefore, end users cannot detect any difference and the existing investment of customers and operators are fully utilized in network integration and construction.
Implementation of ATM cell transparent transmission By creating P2P tunnels, bearing data packets, cells, and bit streams, the Layer 2 emulation service on the PSN traverses the public or private PSN. The original services are emulated to the maximum between two PEs connected by a PW. l
Port-based ATM cell transparent transmission In this mode, the connection between two remote ATM ports is emulated. The port-based ATM cell transparent transmission can be classified into port-based remote ATM cell transparent transmission and port-based local ATM cell transparent transmission.
l
ATM cell transparent transmission in 1-to-1 virtual circuit connection (VCC) mode In this mode, a PW bears an ATM VCC cell. This mode supports all ATM adaptation layer (AAL) types. Because a PW bears only one ATM VCC cell, the tunnel packet does not contain the virtual path identifier (VPI) or virtual channel identifier (VCI). Permanent virtual circuits (PVCs) for the PEs are mapped through the PW, that is, the MPLS PW functions as the ATM switch to support VPI/VCI switching without the need to configure the switching relationship on the PE. ATM cell transparent transmission in 1to-1 VCC mode can be classified into remote ATM cell transparent transmission in 1-to-1 VCC mode and local ATM cell transparent transmission in 1-to-1 VCC mode.
l
ATM cell transparent transmission in N-to-1 VCC mode In this mode, a PW bears multiple ATM VCC cells. This mode supports all AAL types. Because a PW bears multiple ATM VCC cells, the tunnel packet contains the VPI and VCI. This encapsulation mode supports the function of mapping multiple VCs on the same ATM subinterface to a PW, and does not support the function of mapping multiple VCs on different ATM interfaces to a PW or the function of mapping multiple inter-board VCs to a PW. ATM cell transparent transmission in N-to-1 VCC mode can be classified into remote ATM cell transparent transmission in N-to-1 VCC mode and local ATM cell transparent transmission in N-to-1 VCC mode.
l
ATM cell transparent transmission in 1-to-1 virtual path connection (VPC) mode In this mode, a PW bears an ATM VPC cell. This mode supports all AAL types. Compared with ATM cell transparent transmission in 1-to-1 VCC mode, the tunnel packet of this

mode contains only the VCI. The output equipment then determines the destination CE based on the VCI. Because a PW bears only one ATM VPC cell, the PVCs for the PEs are mapped through the PW, that is, the MPLS PW functions as the ATM switch to support the VPI switching without the need to configure the switching relationship on the PE. ATM cell transparent transmission in 1-to-1 VPC mode can be classified into remote ATM cell transparent transmission in 1-to-1 VPC mode and local ATM cell transparent transmission in 1-to-1 VPC mode. l
ATM cell transparent transmission in N-to-1 VPC mode In this mode, a PW bears multiple ATM VPC cells. This mode supports all AAL types. Because a PW bears multiple ATM VPC cells, the tunnel packet contains the VPI and VCI. The encapsulation modes of ATM cell transparent transmission in N-to-1 VPC and N-to-1 VCC modes are the same. ATM cell transparent transmission in N-to-1 VPC mode can be classified into remote ATM cell transparent transmission in N-to-1 VPC mode and local ATM cell transparent transmission in N-to-1 VPC mode.
Encapsulation Modes of ATM cell transparent transmission ATM cell transparent transmission covers the following transparent transmission services: l

Permanent virtual path (PVP)-based transparent transmission service

4.3.3.6 Service Demarcation Tag This topic describes the basic information about service demarcation tags and implementation principles.
Packet Encapsulation on an AC The packet encapsulation mode on an AC is determined by the user access mode. User access modes can be VLAN access and Ethernet access. Each user access mode is described as follows: l
VLAN access: In VLAN access mode, the header of each Ethernet frame sent between CEs and PEs carries a VLAN tag. This tag is a service delimiter that is used to identify users on an ISP network. It is called provider-tag (P-tag).
l
Ethernet access: In Ethernet access mode, the header of each Ethernet frame sent between CEs and PEs does not carry any P-tag. If the frame header carries a VLAN tag, the VLAN tag is the internal VLAN tag of the user packet, and is called user-tag (U-tag). The U-tag is carried in a packet before the packet is sent to a CE and is therefore not added by the CE. The U-tag is used by the CE to identify which VLAN the packet belongs to and is meaningless to PEs.
Packet Encapsulation on a PW Packet encapsulation modes on a PW can be Raw mode and Tagged modė. l
Raw mode The P-tag is not transmitted on the PW. If a PE receives the packet with a P-tag from a CE, the PE strips the P-tag, adds double MPLS labels (outer label and inner label) to the packet, and forwards the packet. If a PE receives the packet without a P-tag from a CE, the PE directly adds double MPLS labels to the packet and forwards the packet. If a PE sends a packet to a CE, the PE adds or does not add the P-tag to the packet as needed, and forwards the packet to the CE. Note that the PE is not allowed to rewrite or remove any existing tag.
l
Tagged mode The frame sent to a PW must carry the P-tag. If a PE receives the packet with a P-tag from a CE, the PE directly adds double MPLS labels to the packet without stripping the P-tag, and forwards the packet; if a PE receives the packet without a P-tag from a CE, the PE adds a null tag and double MPLS labels to the packet and forwards the packet. If a PE sends a packet to a CE, the PE rewrites, removes, or preserves the service delimiter of the packet as needed, and forwards the packet to the CE.

Service Demarcation Tag If you set the access port of an Ethernet service to the C-aware tag or S-aware tag, at least one C-VLAN tag or S-VLAN tag is added to the user packet that is transmitted through the access port. Then you can set a service demarcation tag to identify the access mode of the user packet and the method of handling the outermost C-VLAN tag or S-VLAN tag of the user packet during packet forwarding. l
User: Services gain access to the AC in Ethernet access mode. The outermost C-VLAN tag or S-VLAN tag of a user packet functions as the user VLAN tag (U-TAG) for the forwarding of the user packet.
l
Service: Services gain access to the AC in VLAN access mode. The outermost C-VLAN tag or S-VLAN tag of a user packet functions as the service VLAN tag (P-TAG) and is not involved in the forwarding of the user packet.

Interaction of packets with U-TAGs in the Ethernet raw mode is described as follows: 1.
CE1 transmits packets with Layer 2 encapsulation to PE1. The packets contain U-TAGs but not P-TAGs.
2.
When PE1 receives the packets that contain U-TAGs but not P-TAGs, PE1 considers the U-TAGs as user data without processing them because the U-TAGs are useless to PE1.
3.
When PE1 receives the packets that contain P-TAGs but not U-TAGs, PE1 deletes the PTAGs from the packets because PWs require raw encapsulation and frames transmitted in the PWs cannot contain P-TAGs.
4.
According to the routing table, PE1 selects tunnels and PWs for the packets.
5.
According to the selected tunnels and PWs, PE1 directly adds two types of MPLS tags (outer tunnel tags and inner VC tags) to the packets, performs Layer 2 encapsulation, and forwards the packets.
6.
PE2 receives the packets from PE1 and decapsulates the packets. Specifically, PE2 strips the Layer 2 encapsulation and the two MPLS tags from the packets.
7.
PE2 transmits the decapsulated Layer 2 packets from CE1 to CE2. The packets contain UTAGs but not P-TAGs.

When PE1 receives the packets that contain U-TAGs but not P-TAGs, PE1 considers the U-TAGs as user data without processing them because the U-TAGs are useless to PE1.
3.
When PE1 receives the packets that contain no P-TAGs, PE1 adds the P-TAGs in the packets because PWs require tagged encapsulation and frames transmitted in the PWs must contain P-TAGs.

According to the routing table, PE1 selects tunnels and PWs for the packets.

According to the selected tunnels and PWs, PE1 directly adds two types of MPLS tags (outer tunnel tags and inner VC tags) to the packets, performs Layer 2 encapsulation, and forwards the packets.

4.3.4 Overview of IP over PW IP over PW services are private line services provided by the PTN equipment. In the case of IP over PW services, IP packets are encapsulated into PWs for transmission.
Feature Overview With the growth of wireless networks, the number of base stations that support IP interfaces is greatly increased, and therefore mobile backhaul networks need to access base station services through IP packets. If services are accessed through a traditional L3VPN solution, the restrictions are as follows: l
The access equipment at the edge of a backhaul network must have strong routing capability. This increases the cost of the access equipment.
l
An L3VPN network relies on dynamic routing protocols, and therefore networking is complex and the protection mechanism cannot satisfy network requirements.
On a mobile backhaul network, the trail between a base station and an RNC is fixed. Therefore, if you create IP over PW services between the base station and RNC, the services can fully satisfy service bearing requirements. In the case of IP over PW services, IP packets are encapsulated into PWs. In this manner, IP services from base station are accessed. In addition, features of private line services such as simple networking, easy management, and complete protection are maintained.
Networking As shown in Figure 4-19, an IP over PW service is created between the OptiX PTN 910/950 and OptiX PTN 1900/3900/3900-8 for each base station. The OptiX PTN 910/950 encapsulates IP packets from base stations into a PW, and sends the PW over an IP over PW to the OptiX PTN 1900/3900/3900-8. The OptiX PTN 1900/3900/3900-8 decapsulates the packets and sends the packets to an RNC. In this manner, UNI-NNI service transmission is implemented.

A complete protection mechanism for IP over PW services on PTN equipment is available. For details, see 4.3.5.2 Protection for IP over PW Services.
4.3.5 Principle of IP over PW The PTN equipment supports UNI-NNI IP over PW services and transports the services in a point-to-point manner. In addition, the PTN equipment supports protection for IP over PW services.
4.3.5.1 Implementation Principle for IP over PW The IP over PW feature is based on the MPLS technology. In the case of IP over PW, the accessed IP packets are encapsulated into PWs, and then the packets are transported in point-to-point manner. The PTN equipment supports UNI-NNI IP over PW services. Figure 4-20 shows the service encapsulation process.

4.3.6 PWE3 Service Application This topic describes a typical application of PWE3 services. As an end-to-end Layer 2 service transmission technology, PWE3 provides end-to-end virtual emulation links on edges of packet switched networks (PSNs) for transmitting various services (ATM, Ethernet, and CES) on PSNs. Such a technology can interconnect the traditional network and PSN to share resources and expand the network.

4.4.1 Introduction to VPLS This topic describes basic concepts of the Virtual Private LAN Service (VPLS).
Definition The VPLS, also called Transparent LAN Service (TLS) or virtual private switched network service, is a Layer 2 VPN (L2VPN) technology that is based on Multi-Protocol Label Switching (MPLS) and Ethernet technologies.
Purpose The primary goal of VPLS is to interconnect multiple Ethernet LANs using the Packet Switched Network (PSN). In this manner, these LANs can function as one LAN. VPLS can implement multipoint-to-multipoint VPN networking; therefore, by using the VPLS technology, service providers (SPs) can provide Ethernet-based multipoint services on MPLS backbone networks. In addition, using the VPLS solution in which MPLS virtual circuits (VCs) function as Ethernet bridge links enables SPs to transparently transmit LAN services on the MPLS network.
4.4.2 Reference Standards and Protocols This topic describes the standards compliance and protocols for various technologies used in VPLS. The following table lists the references of this document. Document No.

4.4.3 VPLS Principle VPLS is an L2VPN technology based on MPLS and Ethernet technologies. VPLS can provide multipoint-to-multipoint VPN services, which is better than the earlier point-to-point L2VPN services, and L3VPN services requiring carriers to manage routing information.
VPLS Forwarding Model Figure 4-25 shows the VPLS forwarding model. In the VPLS forwarding model, PEs use Virtual Switch Instances (VSIs) for VPLS forwarding; PEs forward Ethernet frames using the fullymeshed Ethernet emulation circuits or PWs. PEs on the same VPLS network must be fully meshed. That is, PEs are interconnected to PWs. In this manner, packets can be sent directly from the ingress provider edge (PE) to the egress Issue 03 (2014-05-15)

Basic VPLS Transport Components The VPLS network is similar to a switch. On the VPLS network, PWs are set up between VPN sites of each VPN through MPLS tunnels, and Layer 2 packets are transparently transmitted between sites; PEs learn the source MAC addresses and create MAC forwarding entries when forwarding packets, and then map the MAC addresses to attachment circuits (ACs) and PWs. The basic VPLS transport components include ACs, virtual circuits (VCs), forwarders, tunnels, encapsulation, PW signaling protocol, and Quality of Service (QoS). Figure 4-26 shows the location of each basic VPLS transport component on the VPLS network.

The flow direction of VPN1 packets from CE1 to CE3 is used as an example to show the basic direction of the data flow. CE1 forwards Layer 2 packets to PE1. After PE1 receives these packets, the forwarder selects a PW to forward these packets to PE2. Then the forwarder of PE2 forwards these packets to CE3.
VPLS Loop Avoidance On the Ethernet, STP is often enabled on Layer 2 networks to avoid loops. STP, as a private network protocol, however, can only avoid loops between devices on the private network, but not on the ISP network. Therefore, on a VPLS network, full mesh and split horizon are used to avoid loops. To be specific, in each VPLS forwarding instance, each PE must create a tree to all the other PEs; each PE must support split horizon to avoid loops (that is, PEs cannot forward packets between PWs in the same VSI). Usually, PEs in the same VSI are interconnected through PWs. In this sense, splithorizon forwarding means that packets received from the PW on the public network side are forwarded only to the private network side, but not to other PWs. The full mesh between PEs and split horizon ensure the reachability and loop-free in VPLS forwarding. When a customer edge (CE) is connected to multiple PEs, or CEs that are connected to the same VPLS network are interconnected, VPLS cannot ensure that no loop occurs. In such a situation, other methods such as STP must be used to avoid loops. Note that STP can run in the private network of the L2VPN, and all the BPDUs of STP are transparently transmitted on the ISP network.

4 Basic Concepts
Packet Encapsulation on an AC The packet encapsulation mode on an AC is determined by the user access mode. User access modes can be VLAN access and Ethernet access. Each user access mode is described as follows: l
VLAN access: In VLAN access mode, the header of each Ethernet frame sent between CEs and PEs carries a VLAN tag. This tag is a service delimiter that is used to identify users on an ISP network. It is called provider-tag (P-tag).
l
Ethernet access: In Ethernet access mode, the header of each Ethernet frame sent between CEs and PEs does not carry any P-tag. If the frame header carries a VLAN tag, the VLAN tag is the internal VLAN tag of the user packet, and is called user-tag (U-tag). The U-tag is carried in a packet before the packet is sent to a CE and is therefore not added by the CE. The U-tag is used by the CE to identify which VLAN the packet belongs to and is meaningless to PEs.
Packet Encapsulation on a PW Packet encapsulation modes on a PW can be Raw mode and Tagged modė. l
Raw mode The P-tag is not transmitted on the PW. If a PE receives the packet with a P-tag from a CE, the PE strips the P-tag, adds double MPLS labels (outer label and inner label) to the packet, and forwards the packet. If a PE receives the packet without a P-tag from a CE, the PE directly adds double MPLS labels to the packet and forwards the packet. If a PE sends a packet to a CE, the PE adds or does not add the P-tag to the packet as needed, and forwards the packet to the CE. Note that the PE is not allowed to rewrite or remove any existing tag.
l
Tagged mode The frame sent to a PW must carry the P-tag. If a PE receives the packet with a P-tag from a CE, the PE directly adds double MPLS labels to the packet without stripping the P-tag, and forwards the packet; if a PE receives the packet without a P-tag from a CE, the PE adds a null tag and double MPLS labels to the packet and forwards the packet. If a PE sends a packet to a CE, the PE rewrites, removes, or preserves the service delimiter of the packet as needed, and forwards the packet to the CE.
VPLS Packets and Encapsulation Types According to the preceding packet encapsulation modes on a AC and a PW, the VPLS packets and encapsulations can be classified into eight types, as listed in Table 4-4. Table 4-4 VPLS packets and encapsulation types

Typical VPLS Networking Figure 4-27 shows the typical networking of VPLS. VPLS-A and VPLS-B access different UPEs and communicate with each other through the ISP network. From the following figure, it is similar that the user networks of VPLS are in the same LAN. The interfaces used by VPLS must support the ability to broadcast, forward, and filter Ethernet frames. The UPEs are connected using pseudo wires (PWs) and form an emulation LAN. Each PE learns both the MAC addresses of Ethernet packets from the PWs and those from CEs. A PW can use an MPLS tunnel or other tunnels such as GRE and L2TP. A PE is usually a set of MPLS edge equipment and can set up tunnels with other PEs.

4.5.1 Basic Concepts of L3VPN This topic describes the basic concepts of L3VPN, such as site, VPN instance, address space overlapping, and VPN-IPv4 address.
Site The concept of site is frequently used in the VPN technology. The following describes a site from different aspects: l
A site is a group of IP systems with IP connectivity. IP connectivity can be realized independent of SP networks. As shown in Figure 4-28, on the networks on the left, the headquarters of X company in city A is a site; the branch of X company in city B is another site. IP devices in the two sites can communicate without using any carrier's network.

Sites are classified according to the topology relationship between devices rather than the geographic positions of the devices although the devices in a site are geographically adjacent to each other. If two IP systems are geographically separated and connected using private lines, the two systems compose a site if they can communicate without the help of carrier's networks. As shown in Figure 4-28, on the networks on the right, if the branch network of city B is connected with the headquarters network of city A through private lines instead of carrier's networks, the branch network and the headquarters network compose a site.
l
The devices in a site may belong to multiple VPNs. In other words, a site may belong to multiple VPNs. As shown in Figure 4-29, the decision-making department of X company in city A (Site A) is allowed to communicate with the research and development (R&D) department in city B (Site B) and the financial department in city C (Site C). Site B and Site C are not allowed to communicate. In this case, two VPNs, namely, VPN 1 and VPN 2 can be established. Site A and Site B belong to VPN 1; Site A and Site C belong to VPN 2. Site A, thus, belongs to multiple VPNs.

A site is connected to an SP network through CEs. A site may contain more than one CE, but a CE belongs only to one site. According to different sites, you are recommended to use the following devices as CEs: – If the site is a host, use the host as the CE. – If the site is a subnet, use switches as CEs. – If the site comprises multiple subnets, use routers as CEs.
Sites connected to the same carrier's network can be divided into different sets based on policies. Only sites that belong to the same set can access each other. A set of sites is a VPN. NOTE
l If two PEs establish BGP sessions and exchange VPN routing information, one PE is called the peer PE of the other. l The CE that a PE accesses is called the local CE of the PE. l The CE that the peer PE accesses is called the remote CE. l In this chapter, IP addresses of the sites are IPv4 addresses.
VPN Instances A VPN instance is also called a VPN Routing and Forwarding table (VRF). A PE has multiple forwarding tables, including a public routing and forwarding table and one or more VPN instances. That is, a PE has multiple instances, including a public instance and one or more VPN instances.

The differences between a public routing table and a VRF are as follows: l
A public routing table contains the IPv4 routes of all the Provider Edge (PEs) and Provider (Ps), which are generated by routing protocols or static routes of backbone networks.
l
A VRF contains the routes of all sites that belong to the VPN instance. The VRF is obtained by configuring static routes or exchanging the VPN route information between a CE and a PE, and between two PEs.
l
A public forwarding table contains the minimum forwarding information extracted from the corresponding public routing table; a VPN forwarding table contains the minimum forwarding information extracted from the corresponding VPN routing table according to the route management policies.
VPN instances on a PE are independent of each other. They are also independent of the public routing and forwarding table. Each VPN instance can be perceived as a virtual device, which maintains an independent address space and has one or more interfaces that connect the PE associated with the instance. In RFC 2547 (L3VPNs), a VPN instance is called the per-site forwarding table. To be more specific, every connection between a CE and a PE corresponds to a VPN instance (not a one-toone mapping). The VPN instance is bound to the PE interface that connects the CE through manual configuration. The independent address space of a VPN instance is realized by using router distinguishers (RDs). A VPN instance manages VPN membership and routing principles of the directly connected sites by using the VPN target attributes. The following describes RDs and the VPN target in detail.
Relationship Between VPNs, Sites, and VPN Instances The relationship between VPNs, sites, and VPN instances is as follows: l Issue 03 (2014-05-15)
A VPN consists of multiple sites. A site may belong to multiple VPNs. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.
77
iManager U2000 Unified Network Management System Operation Guide for IP Service Management
4 Basic Concepts
l
A site on each PE is associated with a VPN instance. A VPN instance integrates the VPN member relationship and routing principles of the associated sites. Multiple sites compose a VPN based on the rule of VPN instances.
l
VPN instances and VPNs do not have one-to-one mapping relationship.
Address Space Overlapping After receiving private routes from a CE, a PE advertises them to other PEs. As a private network, a VPN independently manages an address realm, also called address space. Address spaces of different VPNs may overlap. For example, both VPN1 and VPN2 use addresses on the segment 10.110.10.0/24. Address space overlapping arises. VPNs can use overlapped address spaces in the following situations: l
The two VPNs do not have the same site.
l
The two VPNs have the same site; however, the devices in the site and the devices using overlapped address spaces in the VPNs do not access each other.
VPN-IPv4 Addresses Traditional BGP cannot process routes of VPNs with address spaces overlapping. Suppose both VPN1 and VPN2 use addresses on the segment 10.110.10.0/24, each of them advertises a route to this network segment, and no load balancing is performed between routes of different VPNs. BGP selects only one route from the two routes. The other route is thus lost. The cause to the aforementioned problem is that BGP cannot distinguish VPNs with the same IP address prefix. To solve this problem, BGP/MPLS IP VPN uses the VPN-IPv4 address family. A VPN-IPv4 address consists of 12 bytes. The first 8 bytes represent the RD; the last 4 bytes stand for IPv4 address prefix, as shown in Figure 4-31. Figure 4-31 VPN-IPv4 address structure Router distinguisher (8-byte) Type field (2-byte)

The Administrator subfield is a 32-bit IPv4 address; the Assigned Number subfield is a 16bit user-defined number. NOTE
When configuring an RD, you only need to specify the Administrator subfield and the Assigned Number subfield. Two types of the configuration formats of an RD are as follows: l The RD format is "16-bit AS number:32-bit user-defined number". For example, 100:1. l The RD format is "32-bit IPv4 address:16-bit user-defined number". For example, 172.1.1.1:1. In this chapter, an RD value does not contain the Type field.
IPv4 addresses with RDs are called the VPN-IPv4 addresses. After receiving IPv4 routes from a CE, a PE converts the routes into globally unique VPN-IPv4 routes and advertises the routes in the public network.
VPN Target The VPN target, also called route target (RT), is a 32-bit BGP extension community attribute. BGP/MPLS IP VPN uses the VPN target to control the advertisement of VPN routing information. A VPN is associated with one or more VPN target attributes, which have the following types: l
Export target: After learning the IPv4 routes from directly connected sites, a local PE converts the routes to VPN-IPv4 routes and sets the export target attribute for those routes. As the BGP extension community attribute, the export target attribute is advertised along with the routes.
l
Import target: After receiving the VPN-IPv4 routes from other PEs, a PE checks the export target attribute of the routes. If the export target is identical with the import target of a VPN instance on the PE, the PE adds the route to the VPN routing table.
That is, the VPN target attribute defines the sites that can receive a VPN route, and the sites from which the PE can receive routes. After receiving a route from the directly connected CEs, a PE associates the route with one or more export target attributes. The process during which VPNv4 routes match the import targets of local VPN instances is called the private network route cross. For details, see the following sections. BGP advertises the attributes along with the VPN-IPv4 route to related PEs. After receiving the route, the PEs compare the export target attributes with the import target attributes of all the VPN instances on the PEs. If the export and import attributes are matched, the route is installed to the VPN routing tables. Similar to RDs, a VPN target shown in Figure 4-32 has the following formats: l
0 The Administrator subfield occupies 2 bytes and the Assigned Number subfield occupies 4 bytes. The Administrator subfield is a 16-bit AS number; the Assigned Number subfield is a 32bit user-defined number.
l
1 The Administrator subfield occupies 4 bytes and the Assigned Number subfield occupies 2 bytes.

NOTE
When configuring a VPN target, you only need to specify the Administrator subfield and the Assigned Number subfield. Two types of the configuration format of a VPN target are as follows: l The VPN-Target format is "16-bit AS number:32-bit user-defined number". For example, 100:1. l The VPN-Target format is "32-bit IPv4 address:16-bit user-defined number". For example, 172.1.1.1:1. In this chapter, a VPN target value does not contain the Type field.
The reasons that using VPN target instead of RDs as the extension community attributes are as follows: l
A VPN-IPv4 route has only one RD, but can be associated with multiple VPN targets. With multiple extension community attributes, BGP can greatly improve the flexibility and scalability of a network.
l
VPN targets are used in controlling route advertisement between different VPNs on a PE. That is, after being configured with the same VPN target, different VPNs on a PE can import routes between each other.
l
On a PE, different VPNs have different RDs; however, the BGP extension community attributes are limited. Using RDs as the attributes to import routes confines the network scalability.
In a BGP/MPLS IP VPN, VPN targets are used to control the advertisement and receipt of VPN routing information between sites. VPN export targets are independent of import targets. An export target and an import target can be configured with multiple values; thus, flexible VPN access control and diversified VPN networking schemes can be implemented.
Relationship Between RD and RT An L3VPN uses RDs to distinguish the prefixes of IPv4 IP addresses that use the same address space, and uses RTs to control the release of VPN routing information. RDs and RTs are similar in structure, but RDs cannot be replaced with RTs. This is because the RT is an extended group attribute of BGP, the route cancellation packets of BGP do not carry the extended attribute. In this case, the received packets have no RT attribute and you need to define the RD attribute separately.
4.5.2 Basic Concepts of MP-BGP This topic describes the concepts related to MP-BGP. The PTN equipment uses the MP-BGP protocol to implement the L3VPN function. Issue 03 (2014-05-15)

iManager U2000 Unified Network Management System Operation Guide for IP Service Management
4 Basic Concepts
Introduction to MP-BGP As previously mentioned, the traditional BGP-4 described in the RFC 1771 can manage only the IPv4 routing information, but cannot manage the routes of VPNs with overlapped address spaces. To correctly process VPN routes, VPNs use Multiprotocol Extensions for BGP-4 described in RFC 2858. MP-BGP supports multiple network layer protocols. In an MP-BGP Update message, information about the network layer protocol is described in the Network Layer Reachability Information (NLRI) and the Next Hop fields. MP-BGP uses the address family to differentiate network layer protocols. An address family can be a traditional IPv4 address family or other address families such as VPN-IPv4 address family. For the values of address families, refer to RFC 1700 (Assigned Numbers). NOTE
The PTN supports multiple MP-BGP extension applications such as VPN extension, which are configured in the corresponding views of the address families. By default, for an IPv4 address family, after the peer address and the AS to which the peer belongs are specified, the local NE has the capability of setting up sessions with its peer. For other address families, the capability of setting up sessions must be manually enabled on the local NE.
The transmission of VPN member information and VPN-IPv4 routes between PEs is implemented by importing extension community attributes into BGP. The following attributes are introduced in MP-BGP: l
MP_REACH_NLRI
l
MP_UNREACH_NLRI
The two attributes are optional non-transitive. BGP speakers without the multiprotocol capability ignore the two attributes and do not pass them to peers. In a VPN, PEs with the multiprotocol capability advertise the VPN routing information to the peer PEs or ASBR PEs supporting multiprotocol through MP-BGP. BGP peers without the multiprotocol capability ignore the attributes, and do not identify and store the VPN routing information. NOTE
Optional non-transitive is a BGP attribute type. If a BGP NE does not support this attribute type, the Update messages with the attributes of this type are ignored, and the messages are not advertised to other peers.
IBGP and EBGP BGP has two running modes, which are shown in Figure 4-33. l
Internal BGP (IBGP)
l
External BGP (EBGP)
When BGP runs in the interior of the autonomous system, it is referred to as IBGP. When BGP runs between different autonomous systems, it is referred to as EBGP.

MP_REACH_NLRI Multiprotocol Reachable NLRI (MP_REACH_NLRI) is used to advertise reachable routes and information about the next hop. The attribute consists of three parts: Address Family Information, Next Hop Network Address Information, and Network Layer Reachable Information. Figure 4-34 shows the format of the attribute.

An SAFI indicates the type of the NLRI field.

If the AFI is 1 and the SAFI is 128, the address in the NLRI field is an MPLS-labeled VPNIPv4 address.
l
Next Hop Network Address Information: consists of the 1-byte length of the next-hop network address and next-hop network address of variable length. A next-hop network address refers to the network address of the next NE on the path to the destination. In MPBGP, before advertising MP_REACH_NLRI to EBGP peers, BGP speakers set the nexthop network addresses as the addresses of the interface that connects the local NE and the remote NE. The next-hop network address remains unchanged when MP_REACH_NLRI is advertised to IBGP peers.
l
NLRI: consists of three parts: length, label, and prefix. Figure 4-35 shows the format of the NLRI field.

l
Prefix: In a BGP/MPLS IP VPN, the prefix field consists of an RD and IPv4 address prefix.
VPNv4 update messages exchanged between PEs or ASBR PEs carry MP_REACH_NLRI. An Update message can carry multiple reachable routes with the same routing attributes.
MP_UNREACH_NLRI Multiprotocol Unreachable NLRI (MP_UNREACH_NLRI) is used to inform a peer to delete unreachable routes. Figure 4-36 shows the format of the attribute.

Withdrawn Routes: Indicates an unreachable route list, which consists of one or more NLRI fields. In the Withdrawn Routes field, BGP speakers can fill the NLRI field the same as the reachable route advertised before to withdraw the route.
Update messages carrying MP_UNREACH_NLRI are sent to withdraw the VPN-IPv4 routes. An Update message can carry information about multiple unreachable routes. If the labels of routes to be withdrawn are specified in the messages, the routes with specified labels are withdrawn. If the labels are not specified, only the routes without labels are withdrawn. Update messages with MP_UNREACH_NLRI do not carry any path-attributes. A peer can delete routes based on labels because different routes are assigned with different labels.
Negotiation of the MP-BGP Capability A BGP NE gets to know the negotiation capability of its peer by checking the capability parameters in the Open messages. If the BGP NE and its peer support the same function, the BGP NE and its peer communicate through the function. The optional parameters of negotiation capability in an Open message consist of three parts: Capability Code, Capability Length, and Capability Value. Figure 4-37 shows the format of the capability parameters. Figure 4-37 Format of BGP capability parameters Capability Code (1 byte) Capability Length (1 byte) Capability Value (variable length)

Capability Code: uniquely identifies the capability type. The value 1 indicates that the BGP speaker has the MP-BGP capability.

At present, BGP does not support dynamic capability negotiation. After a BGP speaker advertises an Open message with optional capability fields, l
If the speaker receives a Notification message from its peer, it indicates the peer does not support the capability. Then the BGP speaker tears down the session with its peer, and sends an Open message without optional capability field to the peer, attempting a new BGP connection.
l
If the peer supports the capability advertisement; however, the capability fields are unknown or unsupported, negotiation fails. Then the BGP speaker tears down the session with its peer and sends an Open message without the optional capability fields (but may carry other optional capability fields) to the peer, attempting a new BGP connection.
After any change of BGP capability, such as enabling or disabling label-routing capability, enabling or disabling address family capability (IPv4 and VPNv4), and enabling GR capability, the BGP speaker tears down the session with its peer and re-negotiates the capability with its peer.
Conditions of Exchanging BGP Routes MP-BGP peers can exchange routes between each other only if the following conditions are satisfied: l
The MP-BGP peers have routes to each other. The operation of BGP is triggered by messages that are transmitted using TCP with the port number as 179. To set up the TCP connection between the peers, the route between the MP-BGP peers must be reachable. A BGP peer is not necessarily a directly connected NE. After a virtual link is set up between a local NE and a remote NE that run BGP, the remote NE becomes a BGP peer of the local NE. To improve the stability of a BGP connection, 32-bit LSR ID interface addresses are used to set up the connection. Instead of discovering routes within an AS, BGP generally imports IGP routes, static routes, or direct routes into BGP routing tables.
l
MP-BGP peers set up and maintain BGP sessions. After a TCP connection is established, an Open message is sent to the peer to attempt a session. After receiving the Open message, the peer responds with a Keepalive message to keep the connection valid. Then the peers begin to exchange messages of other types. MPBGP peers can exchange routes between each other only if the peers can set up and maintain BGP sessions.
Update of VPN-IPv4 Routes A PE must require its peer to re-send BGP Update messages to refresh routes in the following situations: l
The import policy on the PE changes.
l
VPN instances are added or deleted on the PE.
l
The import VPN targets of the VPN instances are added or deleted on the PE.
In these situations, the PE sends Route Refresh messages carrying AFI and SAFI to the peers, which have successfully negotiated the capability with the PE. If the peers do not support the Issue 03 (2014-05-15)

Route Refresh messages, the PE resets the sessions of the peers. After receiving the messages, the peers retransmit all the routes that satisfy AFI and SAFI.
4.5.3 Label Allocation of MP-BGP This topic describes how an MP-BGP label is distributed. On an L3VPN, before advertising private routes to related PEs in the backbone network through MP-BGP, a PE must associate the private routes with MPLS labels. The packets transmitted over a backbone network carry MPLS labels. Before being allocated labels, a PE advertises a route that identifies itself to other PEs in the backbone network through IGP. To reduce the number of LSPs on a network, it is recommended to allocate labels only to 32-bit mask loopback interface and configure the LSR ID and the BGP session to use the IP address of the same loopback interface. Several methods of allocating labels exist. The PTN supports the following method: l
MPLS label allocation based on VPNs A VPN instance is assigned one label. All the routes of the instance share the same label. This helps to save a large number of labels.
4.5.4 VPN Route Selection on PEs VPN route selection on PEs consists of two parts, which are route crossing of a private network and tunnel iteration. In the first part, routing information between PEs are processed. In the second part, VPN packets are forwarded.
Route Crossing of a Private Network The routes exchanged between two PEs through MP-BGP are VPNv4 routes. After receiving VPNv4 routes, a PE processes the routes as follows: l
The PE checks whether the next hop of a route is reachable. If the next hop is unreachable, the route is discarded.
l
The PE discards the routes that do not pass the filtering of the BGP routing policy.
Then the PE matches the remaining routes with the import targets of VPN instances on the PE. The matching process is called route crossing of private networks. The PE matches the VPNv4 routes with local VPN instances without selecting the optimal routes and checking whether the tunnels exist. For a route from the local CE of different VPNs, if the next hop is reachable or can be iterated, the PE also matches the route with the import targets of local VPN instances. The matching process is called local route crossing. NOTE
To correctly forward a packet, a BGP device must find out a directly reachable address, through which the packet can be forwarded to the next hop in the routing table. The route to the directly reachable address is called the dependent route because BGP guides the packet forwarding based on the route. The searching for a dependent route based on the next-hop address is called route iteration.

4 Basic Concepts
Tunnel Iteration To transmit traffic of private networks across a public network, a tunnel is required to transmit the traffic. After the private cross-routes are generated, route iteration based on destination IPv4 prefixes is performed. The proper tunnels (except for the local crossed routes) are searched out. Then the tunnel iteration is performed. The routes are injected into the VPN routing table only after the tunnel iteration succeeds. The process that the routes are iterated to corresponding tunnels is called tunnel iteration. After the tunnel iteration succeeds, the tunnel IDs are reserved for subsequent packet forwarding. A tunnel ID uniquely identifies a tunnel. In VPN packet forwarding, the transmission tunnel is searched out according to the tunnel ID.
Selection Rules of Private Routes Not all the crossed routes that are processed by tunnel iteration are installed to VPN routing tables. Similarly, not all the routes received from the local CE and the local crossed routes are injected into VPN routing tables. For multiple routes to the same destination, choose one route based on the following rules if load balancing is not carried out: l
If a route from the local CE and a crossed route to the same destination exist at the same time, choose the route received from the local CE.
l
If a local crossed route and a crossed route from other PEs to the same destination exist, choose the local crossed route.
For multiple routes to the same destination, choose one route based on the following rules if load balancing is carried out: l
Preferentially choose the route from the local CE. When one route from the local CE and multiple crossed routes exist, choose the route from the local CE.
l
Load balancing is performed between the routes from the local CE or between the crossed routes instead of between the routes from the local CE and the crossed routes.
4.5.5 Route Advertisement of a Basic L3VPN This topic describes how routes of an L3VPN are advertised by using a basic L3VPN. NOTE
A basic L3VPN refers to a VPN on which only one carrier exists, the MPLS backbone network is located in an AS, LSPs serve as tunnels, and PEs, Ps, and CEs do not assume multi-roles. (No device assumes the role of both a PE and a CE.)
Introduction On a basic BGP/MPLS VPN, advertisement of VPN routing information involves CEs and PEs. Ps need to maintain the routes of only the backbone network, and they do not need to know VPN routing information. Generally, PEs maintain the routing information about the VPNs that the PEs access, and they do not need to maintain all VPN routes. The advertisement of VPN routing information consists of the following parts: l Issue 03 (2014-05-15)

Route advertisement from the egress PE to the remote CE
4 Basic Concepts
After the whole process of route advertisement, the local CE and the remote CE can set up reachable routes, and VPN routing information can be advertised on the backbone network. The following describes the three parts of the route advertisement.
Route Advertisement from the Local CE to the Ingress PE After the neighbor or peer relationship is set up between a CE and the directly connected PE, the CE advertises the local routes to the PE. CEs and PEs can run the Routing Information Protocol (RIP), the open shortest path first (OSPF) protocol, or EBGP, or use static routes. The routes advertised by CEs to PEs are standard IPv4 routes regardless of which routing protocol is run. VPN routing and forwarding tables on a PE are isolated from each other and independent of public routing and forwarding tables. After learning routes from a CE, a PE decides to which table the routes should be installed. Static routes and routing protocols cannot enable the PE to make the decision. The decision capability can be realized only through the configuration described as follows. l
If static routes are used between CEs and PEs, you need to specify VPN instances when you configure the static routes.
l
Generally, static routes are used when CEs are located on a stub VPN, or when CEs are hosts or switches. If CEs are hosts or switches, generally, static routes to the sites to which the CEs belong are configured on the connected PEs, and routing protocols are not required. NOTE
l If a VPN receives the routes outside the VPN or the routes advertised by non-PEs, and advertises the routes to a PE, the VPN is called a transit VPN. l A VPN that receives only the routes within the VPN and the routes advertised by PEs is called a stub VPN.
Using static routes between PEs and CEs features simple configurations and can prevent route flapping of CEs from affecting the stability of BGP VPNv4 routes of PEs on the backbone network. l
If IGP is used between CEs and PEs, each VPN uses a process. Different VPNs use different processes. Hence, you need specify VPN instances when you configure the IGP processes.
l
If a site contains backdoor links, the configuration is complicated. For the detailed configuration, see Extension. In addition, there are some restrictions on the usage of IGP between CEs and PEs.
l
If EBGP is run between CEs and PEs, MP-EBGP peers must be configured in the corresponding BGP VPN instance views. When EBGP is run between PEs and CEs, to ensure that routing information is correctly transmitted, nodes located in different places must be assigned with different AS numbers because BGP detects route loops based on AS numbers. However, different VPN sites may use the same AS number because VPN sites use private AS numbers. The AS number of a transit VPN is globally unique.
Route Advertisement from the Ingress PE to the Egress PE Route advertisement from the ingress PE to the egress PE consists of the following parts: Issue 03 (2014-05-15)

l
After learning VPN routes from a CE, a PE adds RDs and VPN targets to these standard IPv4 routes. The VPN-IPv4 routes are then generated.
l
The ingress PE advertises the MP-BGP Update messages containing VPN-IPv4 routes to the egress PE. The Update messages also contain RDs, VPN targets, and MPLS labels. Before the next-hop PE receives the VPN-IPv4 routes, the routes are first filtered by policybased routing (PBR) and then by BGP routing policies.
l
After receiving the routes, the egress PE performs route cross, tunnel iteration, and route filtering; then decides whether to inject the routes into the VRF or not. For the routes that are received from other PEs and are added to the VPN routing table, the local PE stores the following information, which is used in subsequent packet forwarding: – Values of MPLS labels contained in MP-BGP Update messages – Tunnel IDs generated after tunnel iteration succeeds
Route Advertisement from the Egress PE to the Remote CE A remote CE can learn routes from an egress PE through static routes, RIP, OSPF, and EBGP. The route advertisement from the egress PE to the remote CE is the same as that from the local CE to the ingress PE. Note that the routes advertised by the egress PE to the remote CE is common IPv4 routes.
Example for VPN Route Advertisement The following uses Figure 4-39 (BGP runs between CEs and PEs, and the tunnels are LSPs) as an example to describe the advertisement of a route from CE2 to CE1. Figure 4-39 Advertisement of a route from CE2 to CE1 CE1

the route to the VPN routing table. If the egress PE has a VPN routing table of another VPN instance and the import RT of the instance and the export RT of the route are the same, the route is added to the VPN routing table of the instance. 3.
At the same time, the egress PE allocates an MPLS label to the route. Then the egress PE adds the label and VPN-IPv4 routing information to the NLRI field and the export target to the extension community attribute field of the MP-IBGP Update message. After that, the egress PE sends the Update message to the ingress PE.
4.
After receiving the message, the ingress PE filters the route based on BGP routing policies. If the route fails to pass the filtering, the ingress PE discards the route. If the route passes the filtering, the ingress PE performs the route cross. After the route crossing succeeds, the ingress PE performs tunnel iteration based on the destination IPv4 address to find the proper tunnel. If the iteration succeeds, the ingress PE stores the tunnel ID and label and adds the route to the VPN routing table of the VPN instance.
5.
The ingress PE advertises a BGP Update message containing the route to CE2. The advertised route is a common IPv4 route.
6.
After receiving the route, CE2 installs the route to the BGP routing table. CE2 can import the route to the IGP routing table by importing BGP routes to IGP. The preceding process describes the advertisement of a route from CE2 to CE1. To ensure that CE1 and CE2 can communicate, routes need also be advertised from CE1 to CE2 in the same manner.
4.5.6 Packet Forwarding on a Basic L3VPN This topic describes how L3VPN packets are forwarded on a basic L3VPN. NOTE
A basic L3VPN refers to a VPN on which only one carrier exists, the MPLS backbone network is located in an AS, LSPs serve as tunnels, and PEs, Ps, and CEs do not assume multi-roles (No device is a PE and a CE at the same time.)
On an L3VPN backbone network, a P does not know VPN routing information because VPN packets are transmitted between PEs through tunnels. The following uses Figure 4-40 as an example to describe the forwarding of a packet from CE1 to CE2 on the L3VPN. As shown in Figure 4-40, I-L indicates an inner label; O-L indicates an outer label.

After receiving the packet on the interface bound with a VPN instance, the ingress PE processes the packet as follows: l Searching for the corresponding VPN forwarding table based on the RD of the VPN instance l Matching the destination IPv4 prefix and searching for the corresponding tunnel ID l Searching out the tunnel based on the tunnel ID and labeling the packet with I-L l Sending the packet through the tunnel and labeling the packet with O-L1 Then the packet traverses the backbone network by carrying two MPLS labels.
3.
Every P on the backbone network switches the outer label of the packet.
4.
After receiving the packet with two labels, the egress PE processes the packet as follows: l Processing the packet using MPLS l Removing the outer label, O-L2 in this example, using MPLS l Removing the inner label that resides at the bottom of the label stack l Sending the packet, a pure IP packet now, to CE2 through the associated outbound interface The packet is successfully transmitted from CE1 to CE2.

4.5.7 IP DSCP Overview On a DiffServ network, the differentiated services code point (DSCP) is used to identify QoS priority. To perform simple flow classification on IP packets on an IP network, you can use the DSCP labels in the ToS fields of IP packet heads, as shown in Figure 4-41.

If you use the first six bits, that is, IP precedence, in the type of service (ToS) byte in an IP packet head to identify the packet, you can classify all packets into 64 types. After packets are classified, other QoS features can be used for different classes. In this way, the class-based congestion management and flow shaping are implemented. When packets are classified at the edge of a network, DSCP labels are properly added to the packets. Then the packets can be classified inside the network according to the DSCP labels. On the basis of the priority, queuing technologies, such as WFQ and CBWFQ, process the packets in different ways. A downstream network can either use the classification of an upstream network or re-classify data packets according to its own standards. Issue 03 (2014-05-15)

4.5.8 Advertisement of VPNv4 Routes This topic describes the concepts related to advertisement of VPNv4 routes. The PE uses MP-BGP to advertise the IPv4 routes received from the local CE to VPNv4 routes of the peer PE. The rules of advertising VPN-IPv4 routes of MP-BGP are the same as that of BGP. l
When multiple valid routes exist, a BGP speaker advertises only the best route to its peer.
l
A BGP speaker advertises only the routes used by itself to its peer.
l
A BGP speaker advertises the routes obtained using EBGP to all the BGP peers, both EBGP peers and IBGP peers.
l
A BGP speaker does not advertise the IBGP routes to its IBGP peers.
l
A BGP speaker advertises the IBGP routes to its EBGP peers when the synchronization between BGP and IGP is not enabled.
l
After a connection is set up, a BGP speaker advertises all the BGP routes to its new peer.
4.5.9 Introduction to DHCP Relay On an IP-oriented 3G network, after a base station (running the DHCP client) is powered on, the IP address can be automatically obtained from the DHCP server (usually a component of the base station controller) through the DHCP protocol. The PTN equipment on a mobile carrier network can transmit DHCP packets between a base station and a base station controller.
Application of DHCP Relay At the early stage, the DHCP protocol is applicable to only the situation where the DHCP client and server are at the same network section. Hence, to perform dynamic host configuration, a DHCP server must be configured at each network section. This costs a lot. Through DHCP relay, DHCP client packets can be sent to DHCP servers at other network sections, or DHCP server packets can be transparently transmitted to DHCP clients at other network sections. Finally, DHCP clients obtain legal IP addresses. This reduces costs and is easy for centralized management. As shown in Figure 4-42, after being powered on, the base station must automatically obtain the IP address through DHCP. The PTN equipment on the transmission line between the base station and the base station controller transmits DHCP packets between the base station and the base station controller to complete DHCP packet exchange.

In this scenario, the following DHCP relay modes are available: – DHCP relay based on VRFs: The equipment is configured and then enabled with the DHCP relay function. In this case, the equipment identifies and processes the DHCP request packets from all NodeBs. – DHCP relay based on interfaces: The interfaces on the equipment where NodeB services are accessed are configured and then enabled with the DHCP relay function. In this case, communication between each NodeB connected to the equipment through each interface and the DHCP server can be controlled in an accurate manner. NOTE
If a NodeB must communicate with a specific DHCP server, you can adopt the latter mode, DHCP relay based on interfaces.

4.5.10 Principle of DHCP Relay This section describes how the PTN equipment implements relay of DHCP packets between a mobile network base station (running the DHCP client) and a DHCP server (usually a component of a base station controller) in two DHCP relay modes. DHCP relay can implement relay of DHCP packets through an L2VPN or L3VPN network. Before learning the two modes of DHCP relay, you must understand the DHCP packet format, which helps you understand the DHCP relay principle.
DHCP Packet Format DHCP is a protocol based on IP/UDP. Figure 4-46 shows the DHCP packet structure. NOTE

The first port (generally the first UNI port connected to the DHCP client) that processes the DHCP request packets is considered as the DHCP gateway port. Only the gateway port needs to identify and process the DHCP request packets and reply packets. L3VPN DHCP relay has two service transmission scenarios. Figure 4-48 IPoE service scenario FE/GE

The transmission scenarios shown in Figure 4-48 and Figure 4-49 are considered as examples. The processing flows for L3VPN DHCP relay of the equipment as follows: l
The processing procedure of DHCP relay based on VPN routing and forwarding tables (VRFs) is as follows: 1.
When PTN A, which is enabled with DHCP relay, receives DHCP request packets from a certain logical port of NodeB.
2.
PTN A determines whether the number of relays that the current DHCP packets traverse exceeds the limit. If yes, the packets are discarded. Otherwise, the number of relays is added with 1.
3.
PTN A selects the IP address of the server as the destination IP address, and sets the IP address of the packet egress port as the source IP address. NOTE
When the IP address of the server is selected as the destination IP address, the following modes are available: l Sharing mode: The server is selected according to the sharing algorithm. l Broadcast mode: The packets are sent to each server in the VRF.
l
4.
PTN A performs link-layer encapsulation on the packets, performs routing based on the destination IP address, and sends the packets.
5.
After receiving the request packets, the DHCP server sends response packets to the client. These response packets carry the information about the IP address distributed to the client.
6.
PTN A receives the response packets and sends the packets to NodeB after performing IP encapsulation on them.
The processing procedure of DHCP relay based on interfaces is as follows: 1.
On PTN A, the UNI interface through which PTN A is connected to a NodeB is enabled with DHCP relay, and the IP address of the corresponding server is set at the interface.
2.
After the DHCP request packets reach PTN A, the IP address of the server set at the interface is considered as the destination IP address.
3.
PTN A performs link-layer encapsulation (such as ETH encapsulation) and routing based on the destination IP address. Then, PTN A sends the packets to the server. NOTE
After the DHCP server receives the request packets, the remaining processing procedure is the same as that in the case of DHCP relay based on VRFs.
4.5.11 Static L3VPN Compared with dynamic BGP and MPLS L3VPN, static L3VPN does not use dynamic protocols such as BGP, RSVP, and IS-IS. Instead, a static tunnel is deployed between two NEs to establish service connection and services are forwarded between the two NEs based on static routes.
Purpose and Benefit In an LTE mobile backhaul solution, it is recommended that static L3VPN be deployed at the core layer. If dynamic protocols are deployed at the core layer, the network will become unstable. Issue 03 (2014-05-15)

Purpose Integrated service management is necessary for a network on which services accessed in different modes in various scenarios are running. The U2000 supports composite service management. This function is applicable to a scenario where a single service does not meet requirements. With this function, users can flexibly combine PWE3, VPLS, L3VPN, EPL, E-Line, E-AGGR, SDH services into composite services in order to meet the requirements of various solutions such as IP RAN and IP Core.

The U2000 provides a service provisioning window for composite service management, and supports visual and end-to-end service management. These features greatly reduce the requirements on O&M engineers' skills, decrease operation difficulties, simplify network O&M operations, and improve the core competence of carriers.
Definition A composite service is a combination of multiple services, such as PWE3+L3VPN. A composite service consists of service components and connection points. Figure 4-51 shows the model of a composite service. Figure 4-51 Topology of a composite service
l
Service component: A service component is a service that needs to be added to a composite service. For example, the service components of a PWE3+L3VPN composite service include PWE3 and L3VPN services.
l
Connection point: A connection point connects two service components in order to form a composite service. A connection point represents the connection mode for two service components. Connection points are classified into the following types: – PW connection point: Service components are connected by PWs to form a composite service. – Interface connection point: Service components are connected by service access interfaces (interfaces connected to the user side) to form a composite service.
Composite Service Types Composite services are classified based on the service types of the service components that form these services. Different composite services are applicable to different NEs and impose different requirements on service components and connection points, as shown in Table 4-6.

l
Automatic service discovery Qualified services on the U2000 are identified in batches, automatically combined into a composite service, and added to the composite service management window.
l
Convenient service provisioning The U2000 supports manual creation of composite services with little user intervention. – Automatically creates an H-VPLS service with the source being a VPLS or PWE3 service, depending on the specific network requirements. – Adds services that act as service components to composite services on the U2000 and creates connection points between the service components. – Allows users to create or modify services during service component configuration, preventing the interruption of service provisioning because of inappropriate planning. – Automatically calculates connection points to simplify configuration.
l
End-to-end service monitoring This function allows users to view the topology, deployment status, and alarm status of a service, as well as implementing performance monitoring and fault diagnosis.
4.6.3 Composite Service Applications This topic describes typical scenarios where composite services are used. The common application scenarios of composite services are as follows.
H-VPLS Application l
Static PWE3+VPLS composite service On a network such as a MAN access network, if a UPE does not support dynamic PWE3 services, the UPE needs to access NPEs using static PWE3 services. As shown in Figure 4-52, the PWE3 services on the UPEs use static virtual circuits (SVCs) to create PWs with the sink being the NPE; the VSI on the NPE uses LDP as the signaling protocol for the VPLS service.

In VPLS, the bidirectional transmission paths are consistent because the routing information about Layer 2 forwarding is automatically learned through the MAC addresses of the data traffic. If a fault occurs, the VPLS traffic of a UPE is switched to another LSP. The NPE equipment belonging to the VSI deletes the MAC entries of this VSI. After the switchover or the deletion, the MAC entries need to be learned afresh. As shown in Figure 4-53, if a fault occurs on the LSP between UPE 1 and NPE 1, NPE 1 detects the fault and asks the other NPEs to delete the related MAC addresses by sending LDP messages. The UPEs detect the LSP status through MPLS OAM. If a fault is detected, the traffic switchover is performed. After the switchover, the related VSIs on the NPEs learn the MAC addresses afresh. Therefore, the traffic can return through the new NPEs. Before other NPEs learn the MAC addresses, traffic must be broadcast. Issue 03 (2014-05-15)

After the fault is removed, the UPE receives double PWE3 broadcast traffic: one from the NPEs before the switchover, the other from the NPEs after the switchover. The UPE decides which broadcast traffic to be thrown away. After the fault is rectified, the traffic of the UPE is not switched back to the original LSP. This is because the NPE is not triggered to send LDP packets to other NPEs to delete MAC addresses before detecting LSP failures.
PWE3+PWE3 Application As shown in Figure 4-54, the PWE3 service from PE1 to PE4 can be divided into three sections. PW APS protection is configured for the sections from PE1 to PE2 and from PE3 to PE4 and LAG protection is configured for the section from PE2 to PE3. In this way, each fiber has its protection link in each section of the service and therefore the protection capability of the PWE3 service is enhanced.

L2VPN+L3VPN Application In a traditional network environment, a PE-AGG and an NPE are generally deployed at the crossconnection point between the access network and the bearer network so that the L2VPN can access the public network or the L3VPN. The PE-AGG implements the termination and access of the L2VPN; the NPE implements the termination and access of the Layer 3 service. They act as CEs to each other. If an NPE can implement the functions of a PE-AGG and an NPE at the same time, the networking cost is saved and the network complexity is simplified. NPE 1 implements the L2VPN termination and L3VPN access functions by using the VE interface. Therefore, NPE 1 can implement the functions of both the NPE and the PE-AGG in the traditional networking. The access of the L2VPN to the L3VPN is implemented through the loopback between the L2VE and L3VE of the same VE group. Logically, the principle of the loopback between the L2VE and L3VE is similar to that of connecting two physical interfaces through fibers. One of the interfaces is bound to an L2VPN, and the other one is bound to an L3VPN. A VE group is associated with a tag. Different VE groups are set up and bound to different L2VPNs and L3VPNs reNPEctively. This implements multiple pairs of accesses of L2VPNs to L3VPNs. The common scenarios of L2VPN+L3VPN include the PWE3+L3VPN composite service and the VPLS+L3VPN composite service. l Issue 03 (2014-05-15)

4 Basic Concepts
In the scenario shown in Figure 4-56, the NPE functions as the PEs of both the access network and the bearer network. In addition to VPLS, the NPE needs to support the gateway function, including the configuration of IP addresses, access to L3VPNs, ARP, and packet forwarding. When a CE needs to access the L3VPN, the CE sends an ARP request to the gateway interface. The NPE forwards the ARP request and response between the L2VPN and the L3VPN. The access between original L2VPNs, however, is not affected. The NPE needs to broadcast ARP packets locally and in the VSI.
PWE3 in Static L3VPN Application PWE3 in static L3VPN is an LTE-oriented service deployment solution developed for PTN series NEs. On the mobile bearer network, PWE3 services are deployed at the access/aggregation layer, and static L3VPN services are deployed at the core layer, as shown in the following figure. NOTE
Compared with dynamic BGP/MPLS L3VPN services, static L3VPN services do not use dynamic protocols, such as BGP, RSVP, and IS-IS. Static tunnels are established between NEs to carry static L3VPN services, and traffic is forwarded between NEs using static routes. Deploying static L3VPN at the core layer is recommended because the deployment of dynamic protocols at the core layer causes the network unstable.

Inter-AS VPN Application With the wide application of MPLS VPN solutions, different MANs of a carrier or backbone networks of cooperating carriers frequently span multiple ASs. Generally, an MPLS VPN architecture runs within an AS. The routing information of the VPN is transmitted within the AS instead of outside the AS. To realize the exchange of VPN information between different ASs, the inter-AS MPLS VPN model is introduced. The inter-AS Issue 03 (2014-05-15)

iManager U2000 Unified Network Management System Operation Guide for IP Service Management
4 Basic Concepts
MPLS VPN model is an extension of the existing protocol and MPLS VPN framework. Through this model, the route prefix and label information can be advertised over the links between different carriers. The RFC 2547bis presents three inter-AS VPN solutions as follows: l
Inter-AS Option A ASBRs manage VPN routes, through NPEcial interfaces for the VPNs that traverse different ASs. This solution is also called VRF-to-VRF.
l
Inter-AS Option B ASBRs advertise labeled VPN-IPv4 routes to each other through MP-EBGP. This solution is also called EBGP redistribution of labeled VPN-IPv4 routes.
l
Inter-AS Option C PEs advertise labeled VPN-IPv4 routes to each other through multi-hop MP-EBGP. This solution is also called multi-hop EBGP redistribution of labeled VPN-IPv4 routes. NOTE
Currently, the U2000 supports the inter-AS Option A solution.
The networking diagram of the L3VPN Option A solution is used as an example. Figure 4-58 Networking diagram of the inter-AS Option A solution MP-IBGP

As a basic L3VPN application in the inter-AS scenario, Option A does not need NPEcial configurations. In this solution, the ASBRs of the two ASs are directly connected, and they act as the PEs in the ASs, called ASBR PEs. Either of the ASBR PEs takes the peer ASBR as its CE and advertises IPv4 routes to the peer ASBR through EBGP. The ASBRs at the two ends do not need to run MPLS. This solution is easy to implement because MPLS is not required between ASBR PEs and no NPEcial configuration is required. However, Option A has a low scalability because the ASBR PEs manage all the VPN routes and create VPN instances for each VPN. This leads to excessive VPN-IPv4 routes on the PEs. In addition, since common IP forwarding is performed between the ASBR PEs, each inter-AS VPN requires different interfaces, which can be subinterfaces, physical ports, and bound logical interfaces. Therefore, this option poses high requirements for PEs. If a VPN spans multiple ASs, Issue 03 (2014-05-15)

the intermediate ASs must support the VPN services. This requires complex configurations and greatly affects the operation of the intermediate ASs. If the number of the VPNs that cross ASs is small, Option A can be considered.

Automatically Discovering IP Services
About This Chapter The function of automatically discovering IP services can be used to discover a single service or composite services. 6.1 Automatically Discovering Single IP Services A single IP service that has been deployed on the network can be restored to the U2000 for E2E management with the assistance of the network administrator. This mechanism meets the requirements for the scenario where IP services are provisioned before the U2000 is constructed. This mechanism saves time for the administrator and avoids the impact of misoperation on original services. 6.2 Automatically Discovering Composite Services The U2000 can automatically discover services that meet specific requirements, combine these services into composite services, and display the composite services on the Composite Service Management tab. You can perform this operation when a network is being built or after IP services have been configured.

6.1 Automatically Discovering Single IP Services A single IP service that has been deployed on the network can be restored to the U2000 for E2E management with the assistance of the network administrator. This mechanism meets the requirements for the scenario where IP services are provisioned before the U2000 is constructed. This mechanism saves time for the administrator and avoids the impact of misoperation on original services.
Prerequisites Service information does not exist on the U2000 service management module but exists on NEs. The desired NE has been added and the relevant NE configurations have been synchronized to the U2000.
Context NOTE
l Automatically searching for IP services updates IP service data on the U2000. This operation does not affect NE configurations or services running on NEs. l After tunnel, PWE3, or VPLS services are automatically discovered, BFD configurations associated with the services are also discovered and synchronized to the U2000. The supported BFD types include BFD for LSP, BFD for TE, and BFD for PW.
NOTICE After services are deployed on NEs using commands, only NE synchronization is performed on the U2000, and associated services cannot be synchronized to the U2000 service management module. You must manually perform automatic service discovery. Scheduled tasks can be created for automatic service discovery. The U2000 automatically runs a scheduled task to discover services. Scheduled tasks are divided into one-time tasks and periodic tasks. The navigation path to scheduled tasks is shown in Choose Administration > Task Schedule > Task Management (traditional style) from the main menu or select System Management in Application Center and choose Task Schedule > Task Management (application style) from the main menu.. NOTE
Scheduled service discovery results in a high memory usage on the U2000 server and slow U2000 response. Therefore, do not use the U2000 to perform scheduled service discovery at peak hours. Performing this operation at night is recommended.

Description
Add Service
A service that is added to the U2000 using automatic discovery.
Modify Service
A service that is discovered and synchronized to the U2000 because configurations for this service on the U2000 are different from those on the NE. For such a service, more service nodes are configured on the NE than the U2000. This operation helps add service nodes for the service. For other services, you can use the synchronization function provided by the service management module to synchronize data on the NE to the U2000.
Discrete Service
A service that can only exist on an NE because its configurations are incomplete and it cannot be combined into a complete service with other NEs. The service configuration success rate may become lower if many discrete services exist. You are advised to analyze and process discrete services based on the reason displayed on the U2000. For example, delete the discrete service, or use the NE Explorer to complete the service configuration and discover the service again.

Deploying Tunnels and MPLS Protection Rings
About This Chapter Tunnels are used to transmit service traffic between PEs on the packet switching network. In a VPN, a tunnel is an information transmission channel between two entities. The tunnel ensures secure and transparent transmission of VPN information. An MPLS protection ring is located at the server layer but a tunnel is located at the service layer. After service traffic on a tunnel is switched to an MPLS protection ring, a ring label needs to be added to the packets so that the traffic is forwarded based on the ring label, without the need to exchange the tunnel label. After the traffic leaves the ring, the ring label is removed and the tunnel label needs to be exchanged. Table 7-1 Tunnels that can be created for different NEs NE Type

7.2 Creating Tunnels This topic describes how to create tunnels. Tunnels, which ensure the security of information transmission, can bear multiple types of VPN services, such as VPLS, PWE3, and L3VPN services.
Quick Navigation The following table lists three tunnel creation methods. The following table lists two tunnel creation methods. Method
Usage Scenario
Creating a single tunnel
This method is recommended if you want to create a single tunnel.
Creating tunnels in batches
This method is recommended if you want to create dynamic tunnels for multiple NEs and the network type for the new tunnels is Hub-Spoke, Full-Mesh, or Ring. l Full-mesh: All NEs are fully meshed. l Hub-spoke: Spoke sites are fully meshed to hub sites. l Ring: NEs are bidirectionally connected in a ring. NOTE Only routers and PTN NEs support this function.

7 Deploying Tunnels and MPLS Protection Rings
Method
Usage Scenario
Creating tunnels by duplicating existing tunnels
Tunnel duplication applies to typical IP RAN scenarios, such as the multipoint-to-point network, tangent ring, and intersecting ring. Using this function, you can quickly create and deploy tunnels whose paths are similar. Techniques, such as tunnel attribute duplication, automatic route calculation, and label assignment, improve tunnel deployment efficiency. Only static and static CR tunnels can be duplicated. You can duplicate a tunnel as follows: l Duplicate only a tunnel: The original tunnel does not belong to any tunnel protection group. In this case, you can duplicate only the tunnel. l Duplicate a tunnel by protection group: The original tunnel belongs to a tunnel protection group. In this case, the U2000 automatically duplicates a tunnel protection group that is similar to the original tunnel protection group when you duplicate such a tunnel. Only static CR tunnels can be duplicated in this mode.
7.2.1 Creating a Single Tunnel This topic describes how to create a single tunnel and its reverse tunnel.
Prerequisites l
Data synchronization must be performed for the related NE.
l
Layer 2 links or IP links must be configured between routers. For details, see the topology management section.
l
Layer 2 links must be configured between PTN, RTN, and Hybrid MSTP NEs. For details, see the topology management section.
l
ODUk paths have been discovered and Layer 2 links have been generated for OTN NEs.
Configuration Principle The operation information in the figure summarizes the task roadmap. The following operations comply with the roadmap. The following figure takes the router GUI as an example. See the specific GUI according to the device type.

7 Deploying Tunnels and MPLS Protection Rings
Procedure Step 1 Choose Service > Tunnel > Create Tunnel (traditional style) from the main menu or select Bearer Network Service Configuration in Application Center and choose Service > Tunnel > Create Tunnel (application style) from the main menu. Step 2 Configure basic tunnel information, such as the protocol type, signaling type, and protection type. Major Parameter
Settings
Protocol Type
Signaling Type is available only when Protocol Type is set to MPLS. l MPLS: If all NEs that a tunnel passes through support MPLS, set Protocol Type to MPLS. l IP: To implement a cross-IP ATM or CES service, set Protocol Type to IP. NOTE Only PTN NEs support IP tunnels.
Signaling Type
l RSVP TE: You need to specify only the source and sink nodes for an RSVP TE tunnel. The MPLS protocol automatically calculates a route for the tunnel. In addition, you can specify constraint nodes to plan a specific route for the tunnel. You can configure QoS and FRR protection for an RSVP TE tunnel. An RSVP tunnel is more flexible and safer than an LDP tunnel. l LDP: You need to specify only the source and sink nodes for an LDP tunnel. The LDP protocol automatically calculates a route for the tunnel. LDP tunnels can run on any network that supports MPLS. l Static CR: A static Constraint-based Routing (CR) tunnel is created with certain constraints. The mechanism for creating and managing those constraints is called CR. Unlike a static tunnel that requires only routing information, creating a static CR tunnel also requires other configurations, such as the bandwidth, route, and QoS parameters. l Static: Every NE that a static tunnel passes through must be manually specified. NOTE l Routers do not support LDP tunnels. l PTN NEs do not support static tunnels. l Hybrid MSTP, and OTN NEs support static CR tunnels only.
Service Direction
A bidirectional tunnel has paths in both directions, and the paths use the same port and route. A unidirectional tunnel has one path in only one of the directions. NOTE l To create bidirectional tunnels, you need to create a single tunnel and select Create Reverse Tunnel. In this way, two tunnels in opposite directions are created. l This parameter is available only when Signaling Type is set to Static CR.

7 Deploying Tunnels and MPLS Protection Rings
Major Parameter
Settings
Protection Type
When Signaling Type is set to Static CR and Protection Type is set to 1+1 or 1:1, tunnel protection groups are created along with tunnels. NOTE l For protection groups of the 1+1 protection type, services are dually fed from the source end and selectively received by the sink end. If the working tunnel fails, the protection tunnel is used to receive services to implement service switchover. A protection group of the 1+1 protection type occupies more bandwidth but takes shorter switching time. l For protection groups of the 1:1 protection type, services are transmitted over the working tunnel. If the working tunnel fails, the protection tunnel is used to transmit services. The source end sends services and the sink end receives services. A protection group of the 1:1 protection type occupies less bandwidth but takes longer switching time. l During creation of a tunnel enabled with APS, ensure that the values of Outbound Interface/Ring and Inbound Interface/Ring for the protection tunnel are different from those for the working tunnel. If they are the same, APS does not take effect.
Backup Type
Key tunnels on the network require that backup CR-LSPs be configured for primary CR-LSPs. l Hot standby: A backup CR-LSP is created immediately after a primary CR-LSP is set up. If the primary CR-LSP fails, services are switched to the backup CR-LSP. If the primary CR-LSP recovers, services are switched back to the primary CR-LSP. l Cold standby: A backup CR-LSP is created after a primary CR-LSP fails. If the primary CR-LSP fails, services are switched to the backup CR-LSP. If the primary CR-LSP recovers, services are switched back to the primary CR-LSP. l Disabled: A backup CR-LSP is not configured. NOTE The U2000 performs route pre-calculation on RSVP TE tunnels only when Backup Type is set to Hot standby or Cold standby.

Major Parameter
Settings
Configure BFD
Configure BFD when creating a tunnel. Static BFD can be configured only when Create Reverse Tunnel is selected. When configuring static BFD, you can also configure BFD for TE, BFD for Working LSP, and BFD for Protect LSP. When configuring dynamic BFD, you can configure only BFD for Working LSP. l BFD for TE: Millisecond-level fault detection and service protection are achieved when the primary tunnel does not function properly. l BFD for Working LSP: Millisecond-level fault detection and service protection are achieved when the primary working CR-LSP does not function properly. l BFD for Protect LSP: Millisecond-level fault detection and service protection are achieved when the primary protection CR-LSP does not function properly. NOTE l The BFD for TE detection period must be three times longer than the BFD for LSP detection period. Therefore, the value of MinRescSendInt for BFD for LSP must be less than that for BFD for TE. l This parameter is available only when Signaling Type is set to RSVP TE.
Template
Using Template to configure tunnel details is recommended.
Configure As Bypass Tunnel
When Signaling Type is set to RSVP TE and FRR protection needs to be configured to set up a protection tunnel, Configure As Bypass Tunnel must be set. NOTE The RTN equipment does not support this parameter.
Step 3 Select the source and sink NEs of the tunnel by double-clicking them in the Service Topology. Then set the roles of the NEs in the NE Role column. You can also use the following methods to select source and sink NEs: l Method 1: Select the desired NE in the physical topology, right-click, and choose Add from the shortcut menu. l Method 2: 1.
Click Add and choose NE. In the Select NE dialog box, select the desired NEs.
2.
Click OK.
NOTE
When adding optical NEs, select desired OTN NEs in the displayed window.
Step 4 Optional: Configure route constraints for the tunnel. NOTE
If explicit or excluded NEs or interfaces for the tunnel to be created are required, configure route constraints. Otherwise. select only the source and sink NEs for the tunnel.
The methods of configuring route constraints are as follows: Issue 03 (2014-05-15)

l For static CR or static tunnels, right-click the desired NE in the Main Topology and choose Set Working Explicit Route > NE/Interface from the shortcut menu. This method is recommended because route constraints can be configured for both forward and reverse tunnels. Configured route constraints are displayed on the Route Constraint tab. NOTE
Route constraints for static CR or static tunnels are used for route calculation.
l For static/static CR tunnels, click Route Constraint. Then choose Add > NE/Interface in the Set Route Constraint dialog box and configure explicit or excluded nodes. l For RSVP TE tunnels, select the Synchronize Reverse route constraints check box in Route Constraint. Then right-click the desired NE in the Main Topology and choose Set Forward Primary Path Explicit Route > NE/Interface from the shortcut menu. Configured route constraints are displayed on the Route Constraint tab. l For RSVP TE tunnels, click Add on the right of Route Constraint. Then set Interface IP Address and Restriction Type. NOTE
l In consideration of tunnel scalability (adding nodes to tunnels), setting Restriction Type to Loosely include is recommended. l If creating an explicit path fails, modify the path information as prompted and create the path again. l After source, sink, and route constraint NEs are configured for an RSVP TE tunnel, click Review Route. NEs that the tunnel may pass through are highlighted in the physical topology.
Parameter
Description
Loosely include
A tunnel must pass through the interfaces of route restriction objects. In addition, the actual route of the tunnel must pass through the objects in the same sequence as the objects are listed in the explicit path table. For this restriction type, the interface of a route restriction object can be reached through multiple hops.
Strictly include
A tunnel must pass through the interfaces of route restriction objects. In addition, the actual route of the tunnel must pass through the objects in the same sequence as the objects are listed in the route restriction table. For this restriction type, the interface of a route restriction object must be reached through one hop.
Step 5 Optional: Click Details to configure tunnel detail. For details about the parameters, see the GUI reference. Step 6 You are advised to configure MPLS OAM during tunnel creation. If MPLS OAM is not configured during tunnel creation, MPLS protection ring faults may fail to be detected after the tunnel is bound to an MPLS protection ring, which leads to the alarm generation failure. For details about how to configure MPLS OAM, see MPLS OAM Detection. Step 7 Optional: Click Resource Check. Before applying tunnel configurations, verify whether the names, IDs, and labels of the tunnels to be created are valid. Step 8 Click OK. ----End Issue 03 (2014-05-15)

Follow-up Procedure
NOTICE Pay attention to the following items after the tunnel is configured on the port: l
Modifying the port IP address is prohibited. The modification of the port IP address leads to an interruption of the tunnels carried over the port. if PW APS or tunnel APS protection is not configured, base station services will be interrupted. If PW APS or tunnel APS is configured, service switching is triggered upon a fault and the base station services are interrupted intermittently.
l
If the port IP address needs to be modified, the next hop or reverse next hop which is used to carry all tunnels on the peer port must be set to the modified IP address in order to ensure normal service operation. This modification will lead to a short period of service interruption.
In the dialog box displayed after the tunnel is successfully created, click Browse Trail. In the Manage Tunnel window, view the created tunnel. You can perform the following operations: NOTE
The following operations apply only to the tunnels for which Protocol Type is set to MPLS.

Major Parameter
Settings
Network Type
l Full-mesh: All NEs are fully meshed. l Hub-spoke: Spoke sites are fully meshed to hub sites. NOTE When you set Network Type to Hub-Spoke for a tunnel, NE Role must be set to Hub for at least one NE on the tunnel.
l Ring: NEs are bidirectionally connected in a ring. Protocol Type
MPLS: If all NEs that a tunnel passes through support MPLS, set Protocol Type to MPLS. NOTE Protocol Type can be set to MPLS only.
Signaling Type
l RSVP TE: You need to specify only the source and sink nodes for an RSVP TE tunnel. The MPLS protocol automatically calculates a route for the tunnel. In addition, you can specify constraint nodes to plan a specific route for the tunnel. You can configure QoS and FRR protection for an RSVP TE tunnel. An RSVP tunnel is more flexible and safer than an LDP tunnel. l LDP: You need to specify only the source and sink nodes for an LDP tunnel. The LDP protocol automatically calculates a route for the tunnel. LDP tunnels can run on any network that supports MPLS. l Static CR: A static Constraint-based Routing (CR) tunnel is created with certain constraints. The mechanism for creating and managing those constraints is called CR. l Static: Every NE that a static tunnel passes through must be manually specified. NOTE Routers do not support LDP tunnels.
Backup Type
Key tunnels on the network require that backup CR-LSPs be configured for primary CR-LSPs. l Hot standby: A backup CR-LSP is created immediately after a primary CR-LSP is set up. If the primary CR-LSP fails, services are switched to the backup CR-LSP. If the primary CR-LSP recovers, services are switched back to the primary CR-LSP. l Cold standby: A backup CR-LSP is created after a primary CR-LSP fails. If the primary CR-LSP fails, services are switched to the backup CR-LSP. If the primary CR-LSP recovers, services are switched back to the primary CR-LSP. l Disabled: A backup CR-LSP is not configured.

Item
Creating an APS-Based Tunnel Protection Group
Creating an MPLS Protection Ring
Basic principle
A tunnel protection group consists of two tunnels that have the same source and sink but travel along different paths to protect each other. The protection types of the two tunnels are 1+1 and 1:1. Tunnels configured with 1:1 protection support additional services.
An MPLS protection ring is located at the server layer but a tunnel is located at the service layer. After service traffic on a tunnel enters an MPLS protection ring, a ring label is added to the packets so that the traffic is forwarded based on the ring label, without the need to exchange the tunnel label. After the traffic leaves the ring, the ring label is removed and the tunnel label needs to be exchanged.

Item
Creating an APS-Based Tunnel Protection Group
Creating an MPLS Protection Ring
Protection capability
Only the single point of failure scenario is supported. If both the working and protection paths do not function properly, services are interrupted.
Intersecting protection groups need to be configured to provide protection for some multi-point of failure scenarios or some scenarios where LSP linear protection fails. Such a ring helps to isolate faults. If a node fails, a switching is performed within the ring, which does not affect other rings. NOTE An MPLS protection ring does not support any tunnel configured with 1:1 protection.
Resource usage
A lot of resources, even reserved resources for the backup tunnel, are required. OAM needs to be enabled for all tunnels and multiple APS state machines need to run.
An NE on an MPLS protection ring is required to use only two OAM instances and one automatic protection switching (APS) instance. The quantities of OAM instances and APS instances are irrelevant to the number of services.
Configuration efficiency
The configuration is complex because a protection tunnel and a protection tunnel need to be configured for every tunnel.
Configuring a protection tunnel for a new tunnel is not required, which simplifies configuration. The configuration is simple and protection switching can be quickly performed because all services are protected using a ring.
Supported tunnels
Signaling type: static, static CR, RSVP TE, and LDP
Signaling type: static CR Deployment status: deployed
Deployment status: deployed and undeployed
7.3.1 Creating an APS-Based Tunnel Protection Group This topic describes how to create a tunnel protection group. When the working tunnel in a tunnel protection group fails, the services carried over the working tunnel are switched to the protection tunnel to ensure service reliability.

The operation of automatically discovering protection groups can be performed only on one client at the same time.
l
Before creating a protection group, ensure that a working tunnel and a protection tunnel have been created.
l
Before creating a protection group, check whether the working and protection tunnels for the protection group pass through the same nodes or links. Select the working and protection tunnels in the Manage Tunnel window, right-click, and choose View LSP Topology from the shortcut menu. In the Main Topology, select the working and protection tunnels on the Share Link Analyze tab and check whether they pass through the same nodes or links. If they pass through the same nodes or links, the nodes or links blink in the topology. In this case, modifying the working or protection tunnel is recommended to ensure that the working and protection tunnels do not pass through the same nodes or links and improve service reliability. If the working and protection tunnels do not pass through the same nodes or links, use the tunnels to create a protection group.

2.
Configure basic information, such as Protection Type and Switching Mode, about the tunnel protection group. NOTE
l For protection groups of the 1+1 protection type, services are dually fed from the source end and selectively received by the sink end. If the working tunnel fails, the protection tunnel is used to receive services to implement service switchover. l For protection groups of the 1:1 protection type, services are transmitted over the working tunnel. If the working tunnel fails, the protection tunnel is used to transmit services. The source end sends services and the sink end receives services. The PTN chassis-shaped products only support dual-end switchover. The PTN case-shaped products support single-end and dual-end switchover. l For protection groups of the 1:1 protection type, services are transmitted over the working tunnel. If the working tunnel fails, the protection tunnel is used to transmit services. The source end sends services and the sink end receives services. l Single-ended switching refers to a scenario in which when a fault occurs at one end, protection switching occurs only at this end, and does not occur at the remote end. Single-ended switching is not negotiated using negotiation packets. Therefore, it is fast and reliable. l Dual-ended switching refers to a scenario in which when a fault occurs at one end, protection switching occurs at both this end and the remote end. In the case of dual-ended switching, the incoming and outgoing paths of a service are the same. This facilitates service management.

NOTICE During tunnel APS creation, WTR Time must be set to 60s. If the value of WTR Time is less than 60s, tunnel APS switching occurs frequently and services are intermittently alternates between the Up and Down states. In this situation, you need to change the value of WTR Time to 60s. The modification does not affect deployed services.

7.3.2 Creating an MPLS Protection Ring The MPLS-TP shared protection ring technology is developed for PTN NEs based on the characteristics of ring packet networks. Compared with traditional linear protection solutions, this technology can prevent multi-link failures. If an intersecting node is configured, this technology can also prevent node failures. In addition, this technology can be used together with linear protection solutions to improve protection reliability.
Prerequisites l
Only PTN and Hybrid MSTP NEs support this function.
l
The configurations of the relevant NEs have been synchronized to the U2000.
l
The values of OAM Mode for all NEs must be the same.
l
Layer 2 links have been configured before you create an MPLS protection ring. For details about how to configure a Layer 2 link, see Topology Management. NOTE
In the physical topology, check whether Layer 2 links exist between NEs. Alternatively, choose Inventory > Link Management from the main menu and check whether Layer 2 links exist between NEs.
Context l
Information about MPLS protection ring labels is not displayed in U2000 GUIs. The configuration and deployment of all labels are implemented using the U2000. As a great number of ring labels need to be configured, this feature facilitates MPLS protection ring configuration.
l
Intersecting node: An intersecting node consists of two physical nodes and contains information about the source and destination rings. As shown in the following figure, ring 1 and ring 2 are intersected, and the configured intersecting nodes are C and D. Intersecting node C has information about intersecting node D, source ring (ring 1), and destination ring (ring 2). Intersecting node D has information about intersecting node C, source ring (ring 2), and destination ring (ring 1). Every ring uses an intersecting node as a drop node to create a ring path. When two rings intersect, only two intersecting nodes are allowed. If

Center and choose Protection Subnet > IP Protection Subnet > Create MPLS Protection Ring (application style) from the main menu. Step 2 Optional: Determine whether to modify Ring Name or set Remark for an MPLS protection ring as needed. You can also use the default settings displayed on the U2000. NOTE
At present, the U2000 only supports MPLS protection rings for which the ring type is wrapping. Therefore, Ring Type is dimmed and cannot be set. In wrapping mode, an NE that detects a failure initiates a switching, and services are switched to the reverse protection path. On another NE, services are switched back to the original working path and transmitted to the destination NE.
Step 3 Add NEs to the MPLS protection ring. Adding NEs clockwise or anti-clockwise is recommended. The U2000 creates the MPLS protection ring based on the NE adding sequence. Double-clicking NEs in the physical topology to select the NEs is recommended. You can also use the following methods to select NEs: l Method 1: Select the desired NE in the physical topology, right-click, and choose Add from the shortcut menu. l Method 2: Click Add. In the Select NE dialog box, select NEs. NOTE
l The NE that is added later is the west NE of the previously added NE on the MPLS protection ring. l After adding NEs, select an NE record in the NE list and click Up or Down. The sequence of NEs on the MPLS protection ring changes accordingly. l A maximum of 4 MPLS protection rings can be created for a case-shaped PTN NE and these MPLS protection rings all pass through the case-shaped PTN NE. A maximum of 16 MPLS protection rings can be created for a frame-shaped PTN NE and these MPLS protection rings all pass through the frameshaped PTN NE.
Step 4 Optional: Click Detail to configure MPLS protection ring details, such as bandwidth, OAM, and APS information. For details about the relevant parameters, see the GUI reference. Step 5 Click OK to complete the creation of a single MPLS protection ring. NOTE
If creating an MPLS protection ring fails, the U2000 automatically rolls back NE configurations.
Step 6 Optional: Check the connectivity of the new MPLS protection ring. 1.

The two nodes where two rings intersect are considered as a virtual intersecting node. If one intersecting node fails, services can be transmitted to the destination NE using the other intersecting node.
Step 9 Bind a deployed static CR tunnel to an MPLS protection ring. A tunnel can be protected only when it is bound to an MPLS protection ring. Perform steps 1 through 8 to create a single ring or intersecting rings and create a tunnel. Then perform the following operations: NOTE
l A tunnel can be bound to an MPLS protection ring only when at least two intersecting nodes are available for the ring and tunnel. l You can select one or more tunnels and bind the tunnels to rings in batches.
1.
Choose Service > IP Protection Subnet > Search for Ring-bindable Tunnel (traditional style) from the main menu or select Bearer Network Service Configuration in Application Center and choose Protection Subnet > IP Protection Subnet > Search for Ring-bindable Tunnel (application style) from the main menu.
2.
Filter out the required tunnels, right-click, and choose Binding MPLS Protection Ring from the shortcut menu.
3.
Use the optimal MPLS protection ring that is selected by default or click Manually Select to specify an MPLS protection ring.
4.
Click OK. NOTE
l The default optimal ring is determined based on the following rule: Service traffic must enter the ring from the first possible node and leaves the ring at the farthest node after traveling along an as-long-aspossible path. l Principles for selecting the direction in which a tunnel is bound to a ring: The direction of the intersecting node adjacent to the upper ring node is selected. If no adjacent intersecting node exists, either direction may be selected. l The U2000 allows you to specify a protection ring based on the following rule: A newly bound ring cannot overwrite or be overwritten by the ring to which the specified tunnel has been bound. l If binding fails, the tunnel automatically rolls back to the status before the binding. l To unbind a tunnel from an MPLS protection ring, click Unbind MPLS Protection Ring on the MPLS Protection Ring tab. Alternatively, select a tunnel on the Binded Tunnel tab in the Manage MPLS Protection Ring window and click Unbind MPLS Protection Ring.

FAQ 1.
Q: Why is no available NE displayed after I click Add for creating an MPLS protection ring? A: MPLS protection rings can be created only for PTN NEs running V100R003C02 or later. If these NEs do not exist on the U2000, no NE is available for you to create an MPLS protection ring.
2.
Q: After NEs are added one by one to create an MPLS protection ring, only some of the eastbound and westbound interfaces between NEs are automatically displayed. What is the reason for the problem? How do I deal with the problem? A: The U2000 automatically calculates the eastbound and westbound interfaces between NEs only when Layer 2 links exist between the NEs. If some interfaces are not automatically displayed, configure Layer 2 links between the NEs and select eastbound and westbound interfaces.
3.
Q: Are OAM and APS enabled by default for an MPLS protection ring? Are there any constraints for the OAM EXP and ring EXP values? A: OAM and APS are enabled by default when you create an MPLS protection ring. There are not any constraints for the OAM EXP and ring EXP values because the OAM EXP and ring EXP are independent of each other.
4.
Q: If an APS protection group has been configured for a tunnel before the tunnel is bound to an MPLS protection ring, how do I disable APS and enable the tunnel to use protection provided by the MPLS protection ring? A: In the dialog box that is displayed after a tunnel is bound to an MPLS protection ring, click Modify Protection Group. The Manage Protection Group window is displayed and APS protection groups relevant to the tunnel are filtered out. In addition, the Modify Protection Group dialog box is displayed. In this dialog box, set Hold-off Time to a value greater than the value of Hold-off Time for the MPLS protection ring to which the tunnel is bound.
5.
Q: Why does alarm generation fail for some tunnels after the tunnels are bound to an MPLS protection ring and the ingress and egress nodes on the ring are isolated nodes? A: As OAM is not enabled during tunnel configuration, MPLS protection ring faults cannot be detected, which leads to the alarm generation failure. You are advised to enable OAM after tunnel creation.
7.4 Adjusting an MPLS Protection Ring This topic describes how to adjust an MPLS protection ring.
7.4.1 Adding NEs to an MPLS Protection Ring for Capacity Expansion This topic describes how to add NEs to an MPLS protection ring for capacity expansion. With the increase and development of network services, original NEs on the network may fail to meet service requirements. In this case, you need to add NEs and switch some existing services to these NEs to improve overall service processing capabilities.

8.2 Creating an L3VPN Service This topic describes how to create an L3VPN service. The U2000 allows you to create both dynamic and static L3VPN services as well as quickly create static L3VPN services. The differences between dynamic and static L3VPN services are as follows: l
Dynamic L3VPN services use BGP to establish peer relationships between NEs and advertise VPN routes on the backbone networks of service providers, and use MPLS to forward VPN packets on the backbone networks of service providers.
l
Static L3VPN services establish VPN peer relationships between NEs, advertise static routes on the backbone networks of service providers, and use static tunnels to forward VPN packets.
Table 8-2 and Table 8-3 list the differences between static and dynamic L3VPN services. The U2000 supports rapid creation for static L3VPN services for which the value of Network Type is Customized. Compared with common creation, quick creation better meets requirements in usage scenarios, and supports in-pair configuration of NPEs and UPEs. You can click Auto Calculate to generate VPN peer, network-side static route, VPN FRR, and mixed FRR configurations. Protection detection, such as BFD and VRRP, can be configured when a static L3VPN is being created, and the relationship between the protection detection and L3VPN service can also be configured. Table 8-2 Comparison between static and dynamic L3VPN services Static L3VPN Service
Dynamic L3VPN Service
Routing protocol
Static routing protocols are used, and fault locating is simple.
Multiple routing protocols are used, and fault locating is complicated.
Forwarding control
VPN services are carried over static tunnels, and traffic or routes can be easily restricted.
Various routing policies are used to control routes so as to restrict data forwarding paths.
NE adding for expansion
NE adding for expansion of largescale networks is complicated.
NE adding for expansion is flexible.

General
Among the general attributes, the values of RD and RT are automatically displayed as the values configured in the Service Information area. You can change these values as needed. The IP DSCP, VRF Description, Routing Policy, Label Distribution Policy, Tunnel Binding, and Max. Route Count parameters can be set.
DHCP Relay
If you configure and enable DHCP relay based on VRFs, the DHCP request packets that are transmitted from client-side interfaces can be identified and processed.
VRF QoS
Set CIR and PIR as needed. Deploy QoS configurations by using a QoS profile. NOTE During service deployment, the selected Profile Name is delivered to NEs to generate Local Profile Name. You can perform the following operations to create a QoS profile: l In the Select VPN QoS Profile dialog box, right-click and choose Add Global Profile from the shortcut menu. l Choose Configuration > IP QoS Profile > HQoS Profile (traditional style) from the main menu or select Fix-Network NE Configuration in Application Center and choose QoS Profile > IP QoS Profile > HQoS Profile (application style) from the main menu.

Settings
SAI
You can bind multiple interfaces and set the relevant parameters. The CE Information and QoS parameters are optional. You can also click the SAI Configuration tab to add, modify, or delete an SAI or configure SAI QoS. If you configure and enable DHCP relay based on ports, you can accurately control the interaction between the NE connected to each port and the DHCP server. NOTICE Do not modify specified interface IP addressee. If an interface IP address is modified, the static route associated with the interface becomes unavailable and a route loop may occur. NOTE In the IPRAN solution, if the same IP address has been configured for interfaces on the master and slave ASGs (CX series NEs), the MAC addresses of the associated VE interfaces must also be the same, and synchronization must be performed in the interface management window of the NE Explorer.
Route Configuration
Set basic information, such as the BGP peer. The Route Aggregation and Route Import parameters are optional. Select a routing protocol and set the relevant parameters as needed. Click on the right of a static route to copy and import static routes in batches. NOTE l The private BGP protocol is configured in this step. l The ID of the BGP instance must be different from the ID of the MP BGP instance. l You must set Instance ID during IS-IS and RIP configuration. l You must set Instance ID and Area No during OSPF configuration. l On the Static Route tab, you can set Metric Priority and Import Metric Priority To BGP. On multiple PTN NEs that are connected to the same RNC, you can configure private static routes that have different metric priorities and are destined for the same destination IP address and add the metric priorities to BGP. By comparing metric priorities, the remote PTN NEs (not directly connected to the RNC) can determine the preferred route out of the routes. This approach can resolve the issue of uncertain paths to the RNC in a scenario where PTN NEs are dual-homed to an RNC. NOTICE Changing the routing policy or IP address prefix may interrupt services. Exercise caution when you perform this operation.
Step 5 Optional: After the preceding operations are complete, perform the following operations to check the integrity and correctness of service configuration: On the Service Topology tab, select a service link between NEs, right-click, and choose Check Configuration from the shortcut menu to check the service link configurations. If incorrect configurations exist, view the details. If all configurations are correct, proceed with the following step. Issue 03 (2014-05-15)

NOTICE During L3VPN creation, you must set Policy Type to IP FRRand Maximum Length Matchingto Yes and select a correct routing policy with Object Behavior set to Trigger Action, Configuration Type set to Backup Next Hop, and Object Value set to Automatic. Otherwise, the hybrid FRR of L3VPN fails to take effect. Do not modify these parameters after the L3VPN service is deployed. If these parameters need to be modified after the L3VPN service is deployed, strictly comply with the modification requirements. The modification does not affect deployed services. Step 5 Configure a service access interface (SAI). 1.
Click the SAI List tab under SAI Configuration.
2.
Click Create.
3.
Set SAI parameters. For details about the parameters, see the GUI reference. NOTE
l In the LTE solution, if the same IP address has been configured for interfaces on the master and slave L2/L3 nodes (PTN6900 series NEs), the MAC addresses of the associated VE interfaces must also be the same, and synchronization must be performed in the interface management window of the NE Explorer. l In the line-free static L3VPN service interworking scenario, the UNI for the L3VPN must be a VLAN aggregation sub-interface. The UNI for the L2VPN must be an L2VE interface. The L2VE interface and the L3VE interface to which the VLAN aggregation sub-interface belongs are bound in a bridge group for direct service interconnection.
Step 6 Configure a VPN peer relationship. 1.
Click the VPN Peer Configuration tab.
2.
Click Auto-Create. A full-mesh VPN peer relationship is established.
3.
Optional: If a full-mesh VPN peer relationship does not need to be established for all nodes or automatic label allocation by the U2000 is not required, you can manually adjust the automatically calculated VPN peers. For example, right-click a VPN peer and choose the deletion option from the shortcut menu to delete the VPN peer, or change a label to the planned value. For details, see the GUI reference.
Step 7 Optional: Bind the static L3VPN services to a tunnel. The usage scenarios are as follows: When Forward/Reverse Tunnel Binding Type is set to Static Binding or Auto Policy by TE, a forward or reverse tunnel is created along with a static L3VPN service based on the VPN Peer. l Fully Fill: Bulk create the tunnels for which Forward Tunnel Binding Type or Reverse Tunnel Binding Type is set to Static Binding or Auto Policy by TE. l Incrementally Fill: Bulk create the tunnels for which Forward Tunnel Binding Type or Reverse Tunnel Binding Type is set to Static Binding or Auto Policy by TE and that are not manually specified.

NOTICE l For the PTN69 series NEs, you must set Forward Tunnel Binding Type/Reverse Tunnel Binding Type to Auto policy by NE during creation of the L3VPN peer. The tunnel selected for Forward Tunnel Policy/Reverse Tunnel Policy must be correct and work properly. l As the tunnel policy used for different binding types varies, if Forward Tunnel Binding Type/Reverse Tunnel Binding Type is modified for the L3VPN peer, the value of Forward Tunnel Policy/Reverse Tunnel Policy will be cleaned on the U2000 GUI. Operators need to configure a new policy. If the new policy is directly deployed before it is configured, the static routes carried over the L3VPN peer fails to be iterated to the tunnel; as a result, the base station service carried on the L3VPN peer is interrupted. Major Parameter
Settings
Forward Tunnel Binding Type/Reverse Tunnel Binding Type
The available options are as follows: l Static Binding: Only PTN NEs and transport NEs support this option. l Select policy: Only routers support this option. l Auto policy by sequence: Only routers support this option. l Auto policy by NE: Only routers support this option.
Forward Tunnel/ Reverse Tunnel
This parameter is available only when the binding type is set to Static Binding or Auto policy by NE. Configure the forward and reverse tunnels in the Select Tunnel window. If a bidirectional tunnel is selected as the forward tunnel, the bidirectional tunnel is selected as the reverse tunnel by default. NOTE A static L3VPN service can be carried only on a static tunnel. Therefore, only tunnels for which Signaling Type is set to Static CR or Static can be selected.
Forward Tunnel Policy/Reverse Tunnel Policy
A tunnel policy is used to select tunnels for VPN services. Two modes of tunnel policies are available: Bind Application to Tunnel and Tunnel Selection Sequence. The two modes are mutually exclusive. l Bind Application to Tunnel: indicates that the bound tunnel can carry only the specified L3VPN service; therefore, the QoS for the L3VPN service can be guaranteed. l Tunnel Selection Sequence: indicates that tunnels to the same destination are selected by sequence.
1.
Choose Create and Fill Tunnel > Fully Fill or Create and Fill Tunnel > Incrementally Fill.
2.
In the Create Tunnels in Batch dialog box, check the source and sink NEs of the tunnel and set other parameters.

For details about how to create tunnels in batches, see 7.2.2 Creating Tunnels in Batches. The created tunnel is added to In Tunnel or Out Tunnel. Step 8 Configure static routes.
NOTICE You need to configure VPN peer relationships and user-side routes before the calculation of network-side static routes. 1.
Click the Static Route Configuration tab.
2.
Configure both user-side and network-side static routes. l User-side configuration: Static or direct routes are usually used for the user side. If direct routes are used, no parameter needs to be set on this tab. If static routes are used, you need to set parameters such as the destination address and next-hop IP address. Userside static or direct routes are flooded to the peer node based on the VPN peer relationship. l Network-side configuration: Configure static routes used for the network side. After you click Auto-Create, the U2000 automatically generates the network-side routes based on the VPN peer relationship and user-side routes (direct and static routes). You can manually add or modify the static routes.
3.
Optional: Adjust static routes by modifying parameters or deleting some static routes using the shortcut menu option. To display only newly added or modified static routes, select the Display Changed check box. To display all static routes, clear the Display Changed check box. This check box is mainly used to query the changed static routes after a static L3VPN service is modified.
NOTICE To prevent mis-modification, you must lock every newly added static route. NOTE
The U2000 calculates network-side static routes based on the bidirectional VPN peer relationship and the configurations of user-side static and direct routes. For example: l If a user-side static or direct route is configured for node A and a bidirectional VPN peer relationship is established between node A and node B, the U2000 calculates a network-side static route from node B to node A. l If user-side static and direct routes are configured for node A and a bidirectional VPN peer relationship is established between node A and node B, the U2000 calculates two network-side static routes from node B to node A. l If user-side static and direct routes are configured for node A and bidirectional VPN peer relationships are established between node A and node B and between node A and node C, the U2000 calculates two network-side static routes from node B to node A and two network-side static routes from node C to node A.

Step 9 Configure VPN FRR. Major Parameter
Usage Scenario
Settings
VPN FRR
FRR, short for fast reroute, ensures service reliability between PEs.
Manual configuration and automatic calculation are available for VPN FRR and Mixed FRR.
VPN FRR uses protection tunnels as the backup of working tunnels and works with fast detection technologies, such as BFD, to detect the connectivity of the working tunnels. When a working tunnel is faulty, the VPN FRR-enabled PE can switch VPN traffic to the protection tunnel before the VPN routes are converged. This mechanism improves the data forwarding reliability on the public network. IP FRR
IP FRR can specify a sink protection next hop and a sink protection DAI and set backup forwarding information for IPv4 routes. When the active link becomes faulty, the system can switch the traffic immediately to the backup link. This process is irrelevant to route convergence.
Mixed FRR
Mixed FRR is the combination of IP FRR and VPN FRR.
Compared with automatic calculation, manual configuration can specify the backup next hop more accurately. NOTE The source and sink NEs for which VPN FRR/Mixed FRR needs to be configured must be VPN peers for each other, and a network-side route to the peer node must be available. Therefore, you need to configure VPN peer relationships and network-side static routes before VPN FRR/Mixed FRR configuration.
Mixed FRR ensures high reliability of traffic transmission between the CE and PEs. If a link between the CE and a PE fails, the PE can use Mixed FRR to switch traffic bound for the CE to the other PE for transmission.
Step 10 Optional: After the preceding operations are complete, perform the following operations to check the integrity and correctness of service configuration: l On the Service Topology tab, select an NE, right-click, and choose Check VRF from the shortcut menu to check the VRF configurations of the NE. l On the Service Topology tab, select a service link between NEs, right-click, and choose Check Configuration from the shortcut menu to check the service link configurations.

NOTICE l A tunnel policy can be shared by multiple L3VPN services. Deleting the tunnel binding relationship in a tunnel policy may affect multiple services. Therefore, before deleting the tunnel binding relationship in a tunnel policy, ensure that the tunnel to be unbound is not referenced by other services. l Pay attention to the following items during L3VPN service modification: l In the L3VPN service modification window, if you select one or more nodes and click Delete, the VRFs on the nodes corresponding to the L3VPN service are deleted from NEs, which causes the interruption of the L3VPN service. l During L3VPN service modification, if over 12 L3VPN nodes are available, you need to click Add to add the VRFs to be modified to the node list. If you click Delete to delete an unwanted VRF from the list, the VRF is also deleted from the associated NE, which causes service interruption. Therefore, do not click Delete to delete any unwanted node. Instead, you must directly cancel the modification, re-access the modification window, and manually select the node to be modified. l Do not click Delete in the L3VPN service modification window any time. To delete a VRF in the specified L3VPN service, access the Manage L3VPN Service window and click Delete on the VRF tab. After deleting the VRF, you also need to delete relevant peer, static route, and VPN FRR configurations. To add an NE or SAI, click Create or Fast Add on the VRF or SAI tab to modify service settings as needed. Verify the configuration. 1.

requirements in usage scenarios, and supports in-pair configuration of NPEs and UPEs. You can click Auto Calculate to generate VPN peer, network-side static route, VPN FRR, and mixed FRR configurations. Protection detection, such as BFD and VRRP, can be configured when a static L3VPN is being created, and the relationship between the protection detection and L3VPN service can also be configured.
Prerequisites l
The DCN must be disabled on the L3VPN service port.
l
The configurations of the relevant NEs have been synchronized to the U2000.
l
Only PTN NEs support this function.
l
The U2000 supports the quick creation of an L3VPN service only when the networking type is set to Customized.
Context This function applies to two networking scenarios: two pairs of NPEs, and one pair of NEPs +multiple pairs of UPEs.
Configuration Principle The operation information in the figure summarizes the task roadmap. The following operations comply with the roadmap.

Step 2 In the Service Information area, set basic information about the L3VPN service. Major Parameter
Settings
Service name
Specifies the name of a service. The service name uniquely identifies a service on the network.
Signal Type
Specifies the type of signaling. Set this parameter to Static. When static signaling is used, you need to specify VPN peers to flood static routes.
Service Template
A static L3VPN service template contains all attributes required for a static L3VPN service. You can use a default template or create a template that meets a specified policy. Using a service template during L3VPN service creation simplifies parameter settings and service creation operations.
Network Type
A static L3VPN service can be quickly created only when the networking type is set to Customized.
VRF ID
Use the default value Auto-Assign.
Step 3 Add an NE for the L3VPN service. Select the desired NE in either of the following methods: l Method 1: In the physical topology, select a desired NE, right-click, and choose Add NPE Node to Service, Add Slave NPE Node to Service, Add UPE Node to Service, or Add Slave UPE Node to Service from the shortcut menu. This method is recommended. NOTE
l When adding an NE to a service, you need to choose an option from the shortcut menu based on the networking situation and the NE role. l The quick creation function supports two networking scenarios. You can add two pairs of NPEs or add one pair of NPEs and then multiple pairs of UPEs. If you attempt to create other networking scenarios or the NEs are not added in the specified sequence, the shortcut menu options displayed after you right-click a UPE are grayed out. l If the NEs to be operated do not exist in the topology view, you can press Ctrl+F and enter NE names to search for desired NEs.
l Method 2: 1.
On the Quick Create tab, click Add.
2.
Click the Master Node text box for the NPE and click the ... button. In the dialog box that is displayed, select the NE to be added, set Slave Node, and click ... to add a slave node.
3.
Click Add to add the master and slave nodes for the UPE. The method of adding nodes for the UPE is similar to that for the NPE.
4.
Repeat the preceding operations to add multiple NPEs and UPEs.
Step 4 Configure a service access interface (SAI).

1.
Click the Service Topology tab. Select the NE to be operated, right-click, and choose Add SAI from the shortcut menu.
2.
In Physical Topology, double-click an NE and select the VRF to be operated. In the right pane, select desired interfaces.
3.
Click the SAI Configuration tab in the lower-right corner. Then set the subinterface ID and the VLAN ID for the SAI. Generally, subinterfaces are used as SAIs. NOTE
The VLAN ID is automatically configured for the virtual interface, VLAN interface, and VLAN aggregation subinterface on PTN NEs (with PTN6900 excluded).
NOTICE Do not modify specified interface IP addressee. If an interface IP address is modified, the static route associated with the interface becomes unavailable and a route loop may occur. 4.
Click the IP Address tab and configure the IP addresses and subnet masks of SAIs.
5.
Optional: Click the QoS tab and configure the QoS attributes. NOTE
l If a PWE3 service which supports the primary and secondary PWs accesses an L3VPN, the IP addresses and MAC addresses of L3VE interfaces (for PTN 6900s) or VLAN aggregation subinterfaces (for other PTN NEs) on the primary and secondary PWs must be the same. In other situations, the IP addresses of SAIs on all PE nodes on the L3VPN must be different. l In the line-free static L3VPN service interworking scenario, the UNI for the L3VPN must be a VLAN aggregation subinterface. The UNI for the L2VPN must be an L2VE interface. The L2VE interface and the L3VE interface to which the VLAN aggregation subinterface belongs are bound in a bridge group for direct service interconnection.
Step 5 Configure a user-side static route. Static or direct routes are usually used for the user side. If direct routes are used, no parameter needs to be set on this tab. If static routes are used, you need to set parameters such as the destination address and next-hop IP address. User-side static or direct routes are flooded to the peer node based on the VPN peer relationship. Step 6 Click ... next to Auto Calculate to configure auto-calculation rules. Then click Auto Calculate. The VPN peer, network-side static route, VPN FRR, and miex FRR can be automatically generated on the U2000. You can also set the relevant parameters as needed. NOTE
l The prerequisite for auto-calculation on the VPN peer is that Layer 2 links exist between NEs and the links interwork properly. l The BFD indexes traced by the network-side static route must be multi-hop BFD indexes. l PTN 6900 series NEs support only VPN FRR, not IP FRR or hybrid FRR.
Step 7 Optional: After the preceding operations are complete, perform the following operations to check the integrity and correctness of service configuration: l On the Service Topology tab, select an NE, right-click, and choose Check VRF from the shortcut menu to check the VRF configurations of the NE.

Procedure Step 1 Choose Service > VPLS Service > Create VPLS Service (traditional style) from the main menu or select Bearer Network Service Configuration in Application Center and choose Service > VPLS Service > Create VPLS Service (application style) from the main menu. Step 2 Configure service attributes. VPLS allows you to use BGP or LDP to implement control plane functions. l
Create a VPLS service of which Signaling Type is set to LDP/Static. When the signaling type is LDP, PE peers must be manually specified. As the PEs are fully meshed in a VPLS, you must modify the configurations on all the related PEs when adding a new PE. PWs are point-to-point links; therefore, using LDP to establish, maintain, or remove PWs is more efficient. 1.
Enter a service name in the Service Name field.
2.
Set Signaling Type to LDP/Static.
3.
Select a service template.
4.
Set Networking Mode. – Full-Mesh VPLS: All NEs are fully meshed. The U2000 automatically creates PWs between NEs and selects an existing tunnel. – H-VPLS: All the spoke sites are fully meshed to hub sites and the hub sites are fully meshed to each other. The U2000 does not automatically create any PW between NEs. You must manually create PWs between NEs. – Daisy Chain: NEs are bidirectionally connected in a chain. The U2000 automatically creates PWs between the NEs. – Hub-Spoke: The UPE and NPE are connected using a multi-hop PW. – Ring: Bidirectional connections are created between PWs based on the ring. – Customized: The U2000 does not automatically create PWs between NEs. You must manually create PWs between NEs.

Settings
VSI Type
After the mVSI receives a gratuitous ARP packet, MAC addresses of the related service VSIs must be cleared. The mVSI clears the MAC addresses based on the following conditions: l If the number of the related service VSIs reaches the threshold, all the MAC addresses of the service VSIs are cleared and this event is logged. l If the number of the related service VSIs does not reach the threshold, the MAC address of a single service VSI is cleared and this event is logged. l If Service Type is set to Service VPLS, VSI Type can be set only to Service VSI. l If Service Type is set to Management VPLS, VSI Type can be set to Management VSI or Service VSI. l If Service Type is set to E-Tree, VSI Type can be set only to Service VSI. On the metro Ethernet, VRRP instances are used to perform detection and switchover control between the primary and secondary NPEs. The mVSI created on the UPE is dedicated to transmitting detection packets between the NPEs.
Encapsulation Type
l Ethernet: indicates that the encapsulation type is Ethernet. In Ethernet access, the Ethernet frame headers between CEs and PEs do not carry VLAN tags. l VLAN: indicates that the encapsulation type is VLAN that meets the 802.1Q standard. In VLAN access, the Ethernet frame headers between CEs and PEs carry one VLAN tag.

Settings
Tunnel Policy
Specifies a tunnel policy for the tunnel that carries a VPLS service. The tunnel policy determines the tunnel preferred for forwarding traffic between PEs and whether to perform load balancing. You can create a tunnel policy when selecting the VPLS service or use the NE Explorer to create one. Before the tunnel policy is created, the tunnel selection sequence must be specified. If no tunnel policy is created, the LSP tunnel is used by default and load balancing is not performed.
Bound to mVSI
2.
Specifies whether to bind a service VSI to an mVSI. By default, a service VSI is not bound to any mVSI. This parameter is available only to service VSIs. One service VSI can be bound to only one mVSI.
Select an NE in the NE list and click the PW Configuration tab to set relevant PW parameters. NOTE
Skip this step if Signal Type is set to BGP.
Major Parameter
Settings
PW Type
Specifies the encapsulation type of PW data frames. l Ethernet: indicates that data frames do not carry VLAN tags. l Ethernet Tagged Mode: indicates that data frames carry VLAN tags. l Ethernet Dummy: In some Ethernet multicast service scenarios, you need to configure asymmetric PW APS to protect services against link or multiple-node faults. Ethernet Dummy PWs cooperate with the protection PWs in asymmetric PW APS to protect services and prevent loops and broadcast storms that possibly occur during multicast. Ethernet Dummy PWs carry only OAM packets, not service data. NOTE Routers do not support this parameter.
PW ID
Specifies the ID of a PW. The PW ID is automatically allocated by the U2000. You can also enter a PW ID as planned. It must be unique on an NE.
Signaling Type
l Dynamic: indicates that the forward and reverse labels of a PW are automatically allocated by the protocol. l Static: indicates that the forward and reverse labels of a PW are manually configured.

Forward Split Horizon
l Mesh: indicates that the source NE on a PW does not forward the packet that is sent from the sink NE.
Reverse Split Horizon Incoming Label Outgoing Label Forward Tunnel Binding Type
l Spoke: indicates that the source NE on a PW forwards the packet that is sent from the sink NE. Specifies the labels carried by the packet that is sent from the sink NE to the source NE on a PW. This parameter is available only when Signaling Type of the PW is set to Static. Only Select policy is available to routers and switches.
Reverse Tunnel Binding Type Forward tunnel Reverse Tunnel
You can specify a tunnel interface for carrying services, the priority of the tunnel carrying services, and the number of tunnels that participate in load balancing. NOTE Routers do not support this parameter.
Forward PW Control Word
A control word is a four-byte packet header that can identify the packet sequence or serve as a filling bit. l Use preferred: indicates that both ends of a PW use control words. l Not in use: indicates that neither end of a PW uses control words. l Must use: indicates that both ends of a PW must use control words. l Inconsistent: indicates that only one end of a PW uses control words. The control word function is enabled in the following scenarios: l Carrying the sequence number of the forwarded packet is required. If the control word function is supported at the forwarding layer, a 32-bit control word is prefixed to the data packet, indicating the packet sequence. If load balancing is supported, packets may be out of sequence. The control word can be used to number the packets so that the peer can reassemble the packets. l Packets need to be filled to prevent short packets. For example, when an Ethernet exists between PEs or PPP connections are established between PEs and CEs, PPP negotiation may fail because the size of the PPP control packet does not reach the minimum MTU supported by the Ethernet. In this case, adding the control word to the packet can tackle this problem.

Reverse PW Control Word
l Carrying control information about the Layer 2 frame header is required. In some cases, the entire Layer 2 frame does not need to be transmitted when L2VPN packets are transmitted on the network. Instead, the Layer 2 frame header can be removed on the ingress node and then added on the egress node. However, this method is not applicable if some information carried in the Layer 2 frame header is required. Using the control word can tackle this problem because the control word can carry the information that has been negotiated between the ingress and egress nodes.

5
Set BPDU attributes of the SAI. Specify whether the SAI transparently transmits BPDU packets. NOTE In an L2VPN scenario, if the user networks on the two sides both need to run MSTP, the SAIs on PEs must be capable of transparently transmitting BPDU packets from the user side. In this way, BPDU packets from the user side can be used as service packets and transmitted to the user network across the L2VPN. If transparent transmission of BPDU packets is disabled, the SAIs discard BPDU packets from the user side. As a result, MSTP between users is unavailable and the spanning tree cannot be calculated.

You can create multiple PW protection groups for a VSI. After you add two PWs to a PW protection group, the two PWs will work in backup mode. After creating a PW protection group, specify the PW redundancy mode of the group.
Re rou te Pol icy
Specifies the policy used to switch services back to the primary PW after the fault in the primary PW is rectified.
Master/Slave mode: PE1 determines whether a local PW is in the primary or secondary state based on preset forwarding priorities.
l Delayed switchback: Services are switched back to the primary PW after the specified Delay Time. After the switchback, the PE immediately notifies the peer PE on the secondary PW of the fault. In addition, after the specified Delay Time, the PE notifies the peer PE on the secondary PW of fault recovery. l Immediate switchback: Traffic is immediately switched back to the primary PW. This revertive switching policy applies to scenarios in which users hope traffic to be restored as soon as possible. l Non-revertive: Traffic will not be switched back to the primary PW even after the primary PW recovers. Traffic will be switched back to the primary PW only when the secondary PW fails. If you do not want traffic to be frequently switched between the primary and secondary PWs, you can use the Non-revertive.

10.2 Creating PWE3 Services The Pseudo-Wire Emulation Edge to Edge (PWE3) technology is used to carry Layer 2 services. PWE3 simulates the basic behaviors and characteristics of services, such as Asynchronous Transfer Mode (ATM), Frame Relay (FR), Ethernet, low-speed Time Division Multiplex (TDM) circuit, and Synchronous Optical Network (SONET) or Synchronous Digital Hierarchy (SDH), in a Packet Switched Network (PSN).

10.2.1 Creating CES Services One by One or in Batches This topic describes how to create CES services one by one or in batches to transmit TDM signals. The trail configuration method allows you to configure the source and sink nodes of CES services and the PW attributes in the GUI of the U2000, achieving fast service creation.
Prerequisites l
DCN is disabled on the port that carries CES services. For details, see the relevant descriptions of the NE Explorer.
l
CES service (E1/T1 level): A CES service interface is configured, the interface mode is set to Layer 1, and the frame format and frame mode of the interface are configured.
l
CES service (VC4/VC4(3*VC3) level): A CES service interface is configured. The SDH/ SONET mode and VC3/VC4 channel level of the STM-1(VC3/VC4) boards (TND1CQ1) are configured.
l
A tunnel for carrying the services is created.
l
For PTN series NEs, when creating a dynamic PW to carry the services, you must set IGPISIS and MPLS-LDP protocol parameters.
CES Service (E1/T1 Level) A frame format must be set for the interface that is used to carry a CES service, and the frame format must be the same as the service encapsulation format. If the emulation mode of the CES service is CESoPSN, you can set the frame format of an E1 interface to CRC-4 multiframe (recommended value) or Double frame. The frame format of a T1 interface can be SF, ESFNOCRC, ESF, or ESF-JAPAN. If the emulation mode of a CES service is SATop, the frame format of the interface must be non-framing. A frame format must be set for the interface that is used to carry a CES service. A PDH interface on the OptiX PTN 3900, OptiX PTN 1900, OptiX PTN 3900-8, OptiX PTN 950, or OptiX PTN 910 OptiX PTN 960 supports the 30-timeslot or 31-timeslot frame format. The PTN 905 supports only the 24-timeslot frame format. The OptiX PTN 912 supports only the 30-timeslot frame format. In hybrid networking, the frame formats of the local and peer ports must be the same. l
30: In the E1 frame format, timeslots 1 to 15 and 17 to 31 are used to transmit service data.
l
31: In the E1 frame format, timeslots 1 to 31 are used to transmit service data.
CES Service (VC4/VC4(3*VC3) Level) STM-1(VC3/VC4) boards (TND1CQ1) are used to receive CES services, in compliance with SDH and SONET. STM-1(VC3/VC4) boards support VC4/VC4(3*VC3)-level CES services.
Context If multiple CES services need to be created on the same source and sink NEs, create these services in the same GUI. The usage scenarios and restrictions are as follows: l
If the SAIs of the source and sink NEs for a PW are E1 interfaces, multiple SAIs can be selected. PWs are generated based on the sequence of selecting E1 interfaces. You must ensure the mappings when selecting E1 interfaces.

10 Deploying PWE3 Services
If the SAI at one end of the PW between the source and sink NEs is an E1 interface and the SAI at the other end is a CPOS interface, select multiple E1 interfaces at one end and configure multiple lower-order timeslots at the other end. PWs are generated based on the sequence of selecting E1 interfaces and configuring CPOS lower-order timeslots. You must ensure the mappings when selecting E1 interfaces and configuring CPOS lower-order timeslots. For example, if Low TimeSlot for the selected CPOS interfaces is set to 13,25 (values separated by a comma), and the sink interfaces are E1 7/1/10 and E1 7/1/13, PWs are generated in the sequence shown in the following figure.
l
If the SAIs of the PW source and sink NEs are both CPOS interfaces, multiple lower-order timeslots can be configured at both ends. The lower-order timeslot settings at both ends must be consistent.
NOTE
When CES services are created in batches, the protection type can be only Protection-Free or PW Redundancy. Only the ATN 910, ATN 950, and CX600 series NEs support PW Redundancy.

NOTICE l Ensure that MPLS OAM/MPLS-TP OAM parameters are set correctly. l If you need to modify MPLS OAM/MPLS-TP OAM parameter settings after deploying a PWE3 service, ensure that the values of CC Packet Sending Interval and CC Packet Sending Priority set on the source node of the PW are the same as those set on the sink node of the PW. Click Configure MPLS-TP OAM(Y.1731). In the dialog box, set MPLS-TP OAM parameters. Step 10 Optional: If the service protection type is PW Redundancy, PW Backup Protection, or PW APS protection, click Protection Parameter to set protection parameters. l If the service protection type is PW Redundancy or PW Backup Protection, set Protection Mode to 1:1 or 1+1. l If the service protection type is PW APS protection, set parameters as follows. NOTE
Currently, PTN NEs support only 1:1 protection for dual-end protection switching, and the revertive and non-revertive modes. Protection Type can be set to Slave protection pair. If the working PWs, protection PWs, and DNIPWs of multiple MC-PW APS protection groups to be created share the same source and sink with the working PW, protection PW, and DNI-PW of an existing MC-PW APS protection group, you can bind these MC-PW APS protection groups to the existing MC-PW APS protection group (master MC-PW APS protection group). Then these PWs are considered as being in one MC-PW APS protection group to implement synchronous detection and switching. This mechanism reduces the switching time and saves OAM and APS resources. The entire MC-PW APS protection group determines whether to perform protection switching based on the status of the PWs in the master MC-PW APS protection group. Protection Group ID of the slave protection pair must be set to the ID of the protection group that serves as the master PW APS protection group.
Step 11 Optional: Configure the Connection Admission Control (CAC) function. NOTE
Only PTN NEs support this function.
When CAC is selected, the system checks whether the available bandwidth of a tunnel is sufficient for a PWE3 service if the tunnel bound to the PWE3 service is a static CR tunnel and the CIR and PIR are set for the tunnel when the PWE3 service is created. If the available bandwidth is sufficient, the CIR and PIR of the tunnel remain unchanged. If the available bandwidth is insufficient, the CIR of the tunnel increases. After the increase, if the PIR of the tunnel is greater than the CIR, the PIR remains unchanged; if the PIR is smaller than the CIR, the PIR increases until it equals the CIR. Step 12 Select the Deploy check box and click OK. NOTE
l If the Deploy check box is not selected, the configuration data is stored only on the U2000. If the Deploy check box is selected, the configuration data is stored on the U2000 and applied to NEs. By default, the Deploy check box is selected. l If the Deploy and Enable check boxes are selected, services on NEs are available only when the services are enabled.

NOTICE l Ensure that MPLS OAM/MPLS-TP OAM parameters are set correctly. l If you need to modify MPLS OAM/MPLS-TP OAM parameter settings after deploying a PWE3 service, ensure that the values of CC Packet Sending Interval and CC Packet Sending Priority set on the source node of the PW are the same as those set on the sink node of the PW. Step 13 Optional: If the service protection type is PW Redundancy, PW Backup Protection, or PW APS protection or PW FPS protection, click Protection Parameter to set protection parameters. l If the service protection type is PW Redundancy or PW Backup Protection, set Protection Mode to 1:1 or 1+1. l If the service protection type is PW APS protection, set parameters as follows. NOTE
Currently, PTN NEs support only 1:1 protection for dual-end protection switching, and the revertive and non-revertive modes. Protection Type can be set to Slave protection pair. If the working PWs, protection PWs, and DNIPWs of multiple MC-PW APS protection groups to be created share the same source and sink with the working PW, protection PW, and DNI-PW of an existing MC-PW APS protection group, you can bind these MC-PW APS protection groups to the existing MC-PW APS protection group (master MC-PW APS protection group). Then these PWs are considered as being in one MC-PW APS protection group to implement synchronous detection and switching. This mechanism reduces the switching time and saves OAM and APS resources. The entire MC-PW APS protection group determines whether to perform protection switching based on the status of the PWs in the master MC-PW APS protection group. Protection Group ID of the slave protection pair must be set to the ID of the protection group that serves as the master PW APS protection group.
Step 14 Optional: Configure the Connection Admission Control (CAC) function. NOTE
Only PTN NEs support this function.
When CAC is selected, the system checks whether the available bandwidth of a tunnel is sufficient for a PWE3 service if the tunnel bound to the PWE3 service is a static CR tunnel and the CIR and PIR are set for the tunnel when the PWE3 service is created. If the available bandwidth is sufficient, the CIR and PIR of the tunnel remain unchanged. If the available bandwidth is insufficient, the CIR of the tunnel increases. After the increase, if the PIR of the tunnel is greater than the CIR, the PIR remains unchanged; if the PIR is smaller than the CIR, the PIR increases until it equals the CIR. Step 15 Select the Deploy check box and click OK. NOTE
l If the Deploy check box is not selected, the configuration data is stored only on the U2000. If the Deploy check box is selected, the configuration data is stored on the U2000 and applied to NEs. By default, the Deploy check box is selected. l If the Deploy and Enable check boxes are selected, services on NEs are available only when the services are enabled.

Deploying Composite Services
About This Chapter A composite service is a combination of multiple services (for example, PWE3+PWE3) or multiple types of services (for example, PWE3+L3VPN) on the U2000. You can configure composite services in order to create and monitor services that constitute the composite services in a unified manner and to manage a network in E2E mode. 12.1 Composite Service Function Panorama This topic describes composite service functions and associated NEs that the U2000 supports, as well as the navigation paths to these functions. 12.2 Creating a Composite Service You can create a composite service if IP services on the U2000 cannot be automatically discovered as composite services or no qualified composite service exists on the U2000. 12.3 Modifying a Composite Service A base station may be added to or deleted from the live network for network adjustment. In this case, such a base station can be regarded as a service node for composite services, and the network can be quickly adjusted by adding or deleting the service node.

12.2 Creating a Composite Service You can create a composite service if IP services on the U2000 cannot be automatically discovered as composite services or no qualified composite service exists on the U2000. Composite services can be created in user-defined, H-VPLS, PWE3 services in static L3VPN N:1, and PWE3 services in dynamic L3VPN modes. H-VPLS and PWE3 services in static L3VPN 1:1 are provided to quickly create composite services in specific networking scenarios. When using the quick creation function, you need to enter only basic attributes and implement simple configuration to efficiently complete the creation of composite services.

Configuration Principle The operation information in the figure summarizes the task roadmap. The following operations comply with the roadmap.
NOTE
The figure takes the router GUI as an example. See the specific GUI according to the device type.
Procedure Step 1 Choose Service > Composite Service > Create Composite Service (traditional style) from the main menu or select Bearer Network Service Configuration in Application Center and choose Service > Composite Service > Create Composite Service (application style) from the main menu. Step 2 In the General area, set basic attributes for the composite service. 1.
Creation Type must be set to H-VPLS.
2.
Configure BFD. BFD for PW rapidly checks PW connectivity to detect PW faults in real time. Real-time PW fault detection helps trigger PW switching in a timely manner to achieve carrier-class network reliability. The procedure for enabling BFD for PW is as follows: l Select a value from the drop-down list to enable BFD for PW. l Click ... to the right of Configure BFD to set BFD parameters. By default, only the working PW is selected on the U2000. BFD attributes are not associated with PWE3 service protection types. NOTE
This function applies only to routers. Generally, BFD is configured only for the working PW to ensure network reliability under most conditions and save bandwidth and device resources.

Add VPLS Node
Click Add VPLS Node. In the dialog box that is displayed, select VPLS service nodes. The selection methods are as follows: l Selecting existing service nodes: Use existing NEs as service nodes to form an H-VPLS composite service. Existing services can be managed by the composite service in a unified manner. To adjust or expand existing services, use this method. On the Add Service tab, click Filter Criteria and set filter criteria. Then select one or more VPLS services. l Adding new service nodes: If existing services do not meet requirements, use this method to configure new services and add them to an H-VPLS composite service. Click the Add Device tab. Select one or more NEs from the physical topology tree and click
Add VPLS NodeSAI
. Click OK.
Unlike Add VPLS Node, Add VPLS Node-SAI allows you to configure VPLS SAIs on the Add Service tab. Perform the following operations to configure an SAI: 1. Select an NE from the physical topology tree. 2. Select an interface from the interface list. You can click Configure to modify attributes of the selected interface, or click Create to create an interface. 3. On the SAI Configuration tab, set attributes of the interface. See Figure 12-1. NOTE The figure takes the router GUI as an example. See the specific GUI according to the device type. The SAI is usually a subinterface. Perform the following operations to configure a subinterface: select an subinterface from the Subinterface drop-down list, or enter the subinterface ID in ID to create a subinterface. Then set a VLAN ID for the subinterface. This VLAN ID is usually the same as the subinterface ID. You can set other attributes as needed.

Add PWE3 Node
Click Add PWE3 Node. In the dialog box that is displayed, select a PWE3 service node. The selection methods are the same for Add VPLS Node-SAI. Repeat this operation to add more PWE3 service nodes. After you add one PWE3 service node and multiple VPLS service nodes, the U2000 determines the VPLS service node with which the PWE3 service node is associated based on the Layer 2 links between NEs. The U2000 always associates NEs between which the path is the shortest. If multiple shortest paths exist, the U2000 randomly associates two VPLS service nodes with the PWE3 service node. A PWE3 service node can be associated with a maximum of two VPLS service nodes.
Add Switching Node
Click Add Switching Node. In the dialog box, select the required NE and click to configure this NE as a PW switching point. A PW switching point is one hop on a multi-hop PW.
NOTE
The same NE can be added repeatedly in either of the following scenarios: l The NE is added as a PWE3 service node. A PWE3 service is created every time the NE is added. In this way, multiple PWE3 services are created to access multiple user-side service data. l The NE is added as both a PW switching node and PWE3 service node. This enables the NE acting as a PW switching node supports PWE3 creation at the same time. Since the user side has numerous access nodes, adding the same NE repeatedly can reduce the number of NEs on an access ring and NE costs.

In the service topology or service node list, select the VPLS service node. On the VSI Configuration tab, modify VSI attributes as needed. NOTE Generally, the default value provided by the U2000 is used. If the default value is different from the value planned for the live network, change the value as needed.
PW
The U2000 automatically creates PWs between VPLS and PWE3 service nodes based on the following rules: l A VPLS service node can be associated with multiple PWE3 service nodes, but a PWE3 service node can be associated with at most two VPLS service nodes. l If more than two VPLS service nodes are added at the same time, the U2000 selects two VPLS service nodes with the shortest path to the PWE3 service node. l If the PWE3 service node has been associated with two VPLS service nodes, the U2000 no longer calculates the shortest path when more VPLS service nodes are added later. l If the automatically created PW does not meet service planning requirements, perform the following operations to manually change the PW: – On the PW Configuration tab, delete, add, or modify a PW. – If a composite service consists of one PWE3 service node and two VPLS service nodes, change the PW role using one of the following methods: – On the PW Configuration tab, click the General tab and select a value from the Role drop-down list. – In the service topology, select a VPLS service node, rightclick, and choose Set to Working PW or Set to Protection PW from the shortcut menu. – In the service node list area, right-click the desired VPLS service node to change the PW role. NOTE If the PW switching node is a router, set Control Word to -- in the dialog box that is displayed after you select a PW from the PW list and click Detail.

On the PWE3 Service Parameter tab, you can set BPDU, MTU, Service Tag, Redundancy Mode, Receive the traffic through both primary and secondary PWs, and Reversion Delay Time.
PWE3 Protection Parameter
On the PWE3 Protection Parameter tab, you can set Protection Type for a PWE3 service. NOTE If an H-VPLS service consists of two VPLS service nodes and one PWE3 service node, Protection Type can be set to PW APS Protection or PW FPS Protection. After the protection type is set, the U2000 enables MPLSTP OAM and PW OAM at the same time to ensure timely service switching
E-Trunk
In the service topology, select two service nodes of the same type (such as two VPLS nodes), right-click, and choose E-Trunk from the shortcut menu. In the dialog box, set E-Trunk parameters and click OK. E-Trunk is an extension to the Link Aggregation Control Protocol (LACP). It controls and implements inter-device link aggregation. E-Trunk protects PEs and links between a CE and the PEs when the CE is dual-homed to a VPLS or PWE3 network. NOTE The local IP address of one node must be the peer IP address of the other node, and Layer 3 routes must be reachable. Loopback interface addresses are recommended.
Network Protocol
In the service topology, select a service node, right-click, and choose Network Protocol Configuration from the shortcut menu to set network protocol parameters for the service node. The parameters include BGP VPN4 Peer, Dynamic Route, Static Route, Equipment MPLS/MPLS TE, and Interface MPLS/MPLS TE. In general, network protocol parameters are set at the network deployment stage. This configuration method is usually used to view or adjust some parameter settings.
LDP Peer
In the service topology, right-click in the blank area and choose Configure LDP Peer from the shortcut menu. Remote LDP peers need to be configured only for the source and sink NEs of a PW. If a remote LDP peer has been configured for an NE, you can only view the LDP peer configurations.
Step 5 Select the Deploy and Enable check boxes. l Deploy: specifies whether to deploy service component attributes to the specified NE during composite service creation. l Enable: specifies whether to enable service components after their attributes have been deployed to the related NE. A composite service can work properly only after its service components are enabled. After you select the Deploy check box, the Enable check box is selected by default.

12.2.3 Creating a PWE3 in Static L3VPN Service (N:1) This topic describes how to quickly create a PWE3 in static L3VPN service.
Prerequisites This function applies only to PTN NEs. Tunnels carrying services have been deployed. Static L3VPN services meeting specified requirements have been deployed.
Context The PWE3 in static L3VPN composite service must meet the following conditions: l
PWE3: The service type is ETH. The protection type is PW APS. The service has one source and two sinks. The sink SAIs are L2VE interfaces.
l
L3VPN: The signaling type is static. The networking type is Customized. UPE SAIs are L3VE interfaces (for PTN 6900s) or VLAN aggregation subinterfaces (for other PTN NEs).
l
VLAN aggregation subinterfaces are the subinterfaces of L3VE interfaces.
l
The L3VE and L2VE interfaces on the same UPE belong to the same VE bridge group. NOTE
l For a PWE3 in static L3VPN service that is created in N:1 mode, multiple PWE3 services access an L3VPN service. These PWE3 services are configured using the same method. The configuration of one PWE3 service is used as an example. l It is recommended that PWE3 services accessing base stations on the same network segment be planned in the same composite service.
Use the networking diagram in the following figure as an example. The roadmap of configuring a PWE3 in L3VPN service is as follows: 1.
PWE3 services are configured on NE1, NE2, and NE5. MC-PW APS is configured on NE1 for protection. NE1 is dual-homed to NE2 and NE5. DNI-PW is configured between NE2 and NE5 for PW traffic bypass.
2.
A VE bridge group is configured on NE2 and NE5. The L2VE interface is specified as the UNI of the PWE3 service.
3.
An L3VPN service is created on NE2, NE3, NE5, and NE6. The VRFs on NE2 and NE5 are bound to L3VE interfaces (for PTN 6900s) or VLAN aggregation subinterfaces (for other PTN NEs). The VRFs on NE3 and NE6 are bound to the UNIs connected to the MME/ SGW.

Deploying Network Reliability
About This Chapter This topic describes how to deploy IP network reliability using the U2000. As the network and the relevant applications develop, various value-added services are widely deployed on the network and the network bandwidth dramatically increases. If the network is interrupted for a short period, a lot of services running on the network are affected, resulting in serious service loss. Demands for network infrastructure reliability are increasing. 13.1 Configuring BFD Bidirectional Forwarding Detection (BFD) is a universal mechanism used to detect communication faults between forwarding engines. To be specific, BFD detects the connectivity of a data protocol on the same path between two systems. The path can be a physical or logical link, such as a tunnel. BFD can be regarded as a service provided by the system. The upper-layer application provides BFD parameters, such as the detection address and detection time. BFD creates, deletes, or modifies BFD sessions based on these information and informs the upperlayer application of the session status. The upper-layer application then determines whether to take measures accordingly. 13.2 Configuring VRRP Virtual Router Redundancy Protocol (VRRP) is a fault-tolerant protocol. In VRRP, multiple routers are regarded as a virtual router. If the next-hop NE of a host fails, VRRP rapidly switches services to another NE to ensure communication continuity and reliability. The advantage of VRRP is that a default route with higher reliability can be obtained without changing the networking. In addition, no dynamic routing protocols or routing discovery protocols need to be configured on the host.

Usage Scenario
Description
Tunnel
BFD for LSP
BFD detects data plane faults that occur in MPLS LSPs.
BFD for TE
BFD for TE is an end-to-end rapid detection mechanism supported by MPLS TE. BFD for TE rapidly detects faults in links on an MPLS TE tunnel. NOTE In BFD for TE, BFD notifies applications (such as VPN) of faults and triggers traffic switchover between different tunnel interfaces. In BFD for LSP, BFD notifies TE tunnels of faults and triggers traffic switchover between different CR-LSPs in the same TE tunnel. If a service fault occurs, generally, the active/ standby LSP switchover is performed before the tunnel switchover to ensure service stability. Therefore, configuring both MPLS TE detection and TE LSP detection is recommended and the TE LSP detection period must be shorter than the MPLS TE detection period.
L3VPN
BFD for VRF
BFD sessions are bound to VRFs so as to transmit BFD control packets between specified VRFs and to detect the link faults between VRFs. This mechanism reduces the impact of link faults on services. NOTE VRFs do not provide the switchover function. After BFD detection is configured for a VRF, BFD must be bound to a VRRP to implement a VRF switchover through VRRP.

PWE3, HVPLS
BFD for PW
BFD rapidly detects faults on the PW links between local and remote PEs to support VLL FRR and reduce the impact of link faults on services. The U2000 supports the creation of BFD for PW sessions in static mode, that is, by manually configuring identifiers. BFD and VCCV Ping can also be used together to dynamically detect PW connectivity and achieve rapid switchover of upper-layer services.
VPLS, HVPLS
BFD for VSI PW
A BFD session can be bound to a management VSI PW to monitor the status of the management VSI PW so as to monitor service VSIs.
NOTE
BFD detection is usually used in the following scenarios: l
BFD for VRRP: In VRRP-based reliability networking, BFD provides rapid detection for links between the primary and secondary routers. If a link fault occurs, BFD notifies the VRRP module of the fault to achieve rapid switchover between the primary and secondary routers.
l
BFD for FRR: l BFD for LDP FRR: BFD detects protected interfaces and triggers an LDP FRR switchover for MPLS-based products. l BFD for IP FRR and BFD for VPN FRR: BFD detects NE faults and triggers IP FRR and VPN FRR. BFD provides reliability for MPLS-based applications, such as VPN FRR, TE FRR, and VLL FRR, to achieve service protection.

Setting Requirements Bind LSP Type: In general, BFD is configured to detect the primary LSP. If a fault occurs, traffic is switched to the backup LSP. If services have high requirements for fault detection, BFD can be configured for both the primary and backup LSPs to speed up fault detection and switchover.
IP link
IP link
IP Bind Type: l Specified IP Address: To check the connectivity of a single-hop or multi-hop link, select this value. l Default Multicast Address: To check the connectivity of a link between Layer 2 or 3 interfaces without IP addresses, select this value. BFD control packets are then sent to the multicast address to check the physical status of the link. Remote IP Address: IP address of the sink NE to be detected Out Interface: If this parameter is not set, a multihop route can be detected. If this parameter is set, a single-hop route, that is, a route that uses this interface as the outbound interface and the peer IP address as the next hop is detected. Local IP Address: l If this parameter is not set, the U2000 searches the local routing table for an outbound interface matching the peer IP address and uses the IP address of this interface as the source IP address from which BFD packets are sent. l When both BFD and URPF are enabled, you need to set the source IP address of BFD packets because URPF checks the source IP address of every received packet. The system only checks whether the source IP address is valid (for example, the source IP address cannot be a multicast or broadcast address), without carrying out any correctness check. Therefore, you must ensure the correctness of the source IP address.

Click OK to deploy the configurations to NEs. The newly configured BFD session is displayed in the list of the BFD Session Configuration Management window. ----End
Follow-up Procedure l
After the preceding operations are complete, you can learn about BFD running conditions by checking the BFD session status. Before checking the BFD session status, perform synchronization in the NE Explorer. Double-click an NE in the Main Topology to access the NE Explorer. In the NE Explorer, choose BFD Management > Service Detection Configuration > VRF Detection Configuration from the navigation tree. In the VRF Detection Configuration window, right-click in the blank area and choose Synchronize from the shortcut menu.
l
As previously described, the upper-layer application determines whether to take measures against the change of BFD session status. The upper-layer application is usually VRRP. For details about VRRP, see 13.2 Configuring VRRP.
13.2 Configuring VRRP Virtual Router Redundancy Protocol (VRRP) is a fault-tolerant protocol. In VRRP, multiple routers are regarded as a virtual router. If the next-hop NE of a host fails, VRRP rapidly switches services to another NE to ensure communication continuity and reliability. The advantage of VRRP is that a default route with higher reliability can be obtained without changing the networking. In addition, no dynamic routing protocols or routing discovery protocols need to be configured on the host.
Prerequisites Deployment Status of the service for which VRRP needs to be configured is Deployed. NOTE
"√" indicates that the device supports this service on the U2000. "-" indicates that the device does not support this service on the U2000.

Type of Bound Service
Setting Requirements
VR IP
Specifies the virtual IP address of a VR. The virtual IP address of the VR must be on the same network segment as the IP address of the specified interface. Otherwise, the configuration fails. For users who have the same VRRP reliability requirements, a backup group can be configured with multiple virtual IP addresses to provide services for different user groups. This facilitates management and prevents the default gateway address on the user side from being changed with VRRP configurations. When both VRRP and static ARP are configured on an NE and VRRP is configured on a Dot1q/QinQ termination subinterface or a VLAN interface, do not use the mapping IP address corresponding to the static ARP table entries related to these interfaces as the VRRP virtual address. Otherwise, the related NEs fail to forward packets between each other.

Flowdown
If the flowdown function is configured and the mVRRP backup group is in the non-Master state, the interface where the service VRRP backup group bound to the mVRRP backup group is configured goes Down, and the status of the service VRRP backup group changes to Initialize. l flowdown: This mode is used on a network where the upstream and downstream traffic forwarding paths must be the same. On a network configured with a firewall and a VRRP backup group, upstream traffic flows through the master device and the downstream traffic flows through either the master or backup device. If downstream traffic flows through the backup device and the firewall detects the inconsistency between the upstream and downstream traffic forwarding paths, the backup device has to discard downstream traffic. The flowdown mode allows the downstream traffic to be forwarded through the master device so that all traffic is properly forwarded. l unflowdown: This mode is used on a network where the upstream and downstream traffic forwarding paths do not need to be the same. In this mode, the status of the mVRRP backup group is the same as the status of the bound VRRP backup group. Upstream traffic flows through the master device and reaches the upper-layer network, and downstream traffic flows through either the master or backup device and reaches the user side. NOTE This parameter is valid only in the following conditions: l A service VRRP backup group is bound to an mVRRP group, and this parameter is set for the service VRRP backup group. l This parameter applies only to L3VPN services and routers.

l BFD sessions or interfaces Select the Tracked more BFD sessions or interface check box, click Create Row, and add the monitoring objects for the working and protection VRs. NOTE
On the Metro Ethernet, VRRP runs between NPEs. BFD between NPEs is called peer BFD, and BFD between the NPE and UPE is called link BFD. Peer BFD and link BFD are used to detect the link and NE faults between NPEs and between the NPE and UPE respectively. Peer BFD and link BFD directly affect the status of a backup group without changing the priority of the backup group. As a result, in non-preemption mode, the priority of a backup router may be higher than that of a master router after peer BFD and link BFD are configured.
Step 5 Deploy the configurations to NEs. Click Finish to deploy the configurations to NEs. The newly configured VRRP is displayed in the list of the VRRP-Based Detection Configuration Management window. ----End
Result After the preceding operations are complete, view the following information in the VRRPBased Detection Configuration Management window: l
Working NE, Working State, Protection NE, and Protection State: All VRRP backup groups configured for the PWE3 service and the master and backup states of NEs in a VRRP backup group are displayed.
l
Service Component Associated with VR tab: Service components for tracking VRs are displayed. These service components determine their own active/standby states by tracking the VR status.
l
VR Tracking Object tab: All objects (usually interfaces, BFD sessions, and OAM) monitored by the VRRP backup group and priority adjustment values (for example, 10) are displayed. The VRRP backup group adjusts priorities based on the status of monitored objects and determines whether to perform a master/backup switchover based on the adjusted priorities.
ARP dual-NE hot backup can be configured for L3VPN services to back up ARP information between two NEs running VRRP and maintain ARP information synchronization between the master and backup NEs. After a VRRP active/standby switchover is performed, downstream traffic is properly transmitted without MAC address learning in ARP entries. This mechanism effectively resolves the packet loss problem that occurs because ARP information is not obtained in time after a switchover is complete. 1.

15.4 Intelligent Service Fault Diagnosis Packet services and native Ethernet services are widely applied on live networks. If a service fails, it is hard and time-consuming to diagnose and troubleshoot the fault due to network complexity. To address this issue, the U2000 provides an intelligent service fault diagnosis function that can quickly locate and diagnose faults on various types of services.
15.4.1 Service Fault Diagnosis The U2000 provides intelligent service fault diagnosis and troubleshooting suggestions for various types of services to diagnose service faults more quickly and accurately.
Context A large variety of services are applied on live networks. If a service fails, it is time-consuming to diagnose and troubleshoot the fault due to network complexity. With the development of packet switching technologies, more and more transport devices support the packet feature. Compared with a traditional connection-based SDH network, a packet-based network is more flexible and has more complex service configurations. In addition, the packet-based network does not have overhead fields to indicate its physical status. This makes fault troubleshooting difficult. The networking diversity and technology complexity impose higher requirements on O&M capabilities. The intelligent service fault diagnosis function of the U2000 can automatically diagnose faults on various types of services in a layered manner. It provides abundant alarms and can locate fault points accurately and provide accurate suggestions to guide users through troubleshooting. It simplifies network O&M and improves the O&M efficiency. Table 15-1 shows that the intelligent U2000 analysis method replaces the traditional service fault diagnosis method which heavily relies on O&M engineers and improves the fault locating efficiency.

Currently, the PWE3 services that support the fault diagnosis include E-Line services and CES services. Only the PTN supports the fault diagnosis of CES services.
Diagnosis Procedure PWE3 services contain four layers, including the service layer, PW layer, tunnel layer, and link layer. The fault of service-layer diagnosis automatically triggers PW-layer fault diagnosis while the fault of tunnel-layer diagnosis automatically triggers link-layer fault diagnosis. Figure 15-3 shows the fault diagnosis procedure for PWE3 services. The process are automatically performed on the U2000.

15.4.1.2 VPLS Service Fault Diagnosis This topic describes how to diagnose faults for VPLS services in typical scenarios.
VPLS Scenario As shown in Figure 15-4, tunnels are established between any two NEs on the VPLS network, where PWs are used to forward Ethernet frames. User networks where CEs 1, 5, and 6 reside are interconnected through the VPLS network, forming a larger Ethernet (VPN 1). The three user networks are assigned the same VLAN ID and communicate with each other through VPN 1. Similarly, VPN 2 is established by interconnecting user networks where CEs 2, 3, and 4 reside. Data streams from CE 1 to CE 5 and from CE 1 to CE 6 traverse VPN 1. When Layer 2 packets from CE 1 reach NE 1, NE 1 selects a PW and transparently forwards these packets to NEs 2 and 4. Then, NEs 2 and 4 forward them to destination CEs. When you start fault diagnosis for VPLS services on VPN 1, VPLS services from nodes to nodes are split into multiple node-to-node E-Line services. In this case, the services are diagnosed possibly from the following paths: NE 1->NE 2 and NE 1->NE 4. Issue 03 (2014-05-15)

15.4.1.3 Composite Service Fault Diagnosis This topic describes how to diagnose faults for composite services in typical scenarios.
VPLS+PWE3 Scenario As shown in Figure 15-6, PWE3s access VPLS services in a dual-homed manner. In this scenario, NE 1 originates primary and backup PWs to transmit PWE3 services to NEs 2 and 3. When the PW between NEs 1 and 2 malfunctions, traffic is immediately switched to that between NEs 1 and 3. This ensures the stability of PWE3 services transmitted from NE 1. On the VPLS network, NEs establish tunnel-based PWs destined to VPNs 1 and 2, and transmit and receive Layer 2 packets transparently over the PWs. When forwarding packets, NEs learn source MAC addresses and establish MAC forwarding entries. This maps MAC addresses to ACs and PWs. When you start fault diagnosis in the VPLS+PWE3 scenario, VPLS services from nodes to nodes are split into multiple node-to-node E-Line services. In this case, the services are diagnosed from the following paths: NE 1->NE 2->NE 4 and NE 1->NE 2->NE 5.

Test Type
Function
Remarks
LB
Checks whether the local NE is properly connected to the peer NE by sending test packets and receiving response packets. The LB test is similar to the Ping test. In an LB test, LB packets are unicasted from an MEP to another MEP in the same MA. The receiving node checks the destination MAC address of the LB packets. If the destination MAC address is the MAC address of the receiving node, the receiving node sends a loopback reply (LBR) message to the source node. The transit nodes only implement Layer 2 forwarding.
The services and NEs that support the LM and DM tests are as follows:
LT
Checks the path from the local NE to the peer NE or locates faults by sending test packets and receiving response packets. The LT test is similar to the traceroute test.
LM
Measures the number of packets lost between a pair of MEPs.
DM
Measures the delay and jitter between a pair of MEPs.
Test
Implements on-demand diagnostic testing. When the test packet function is configured, the MEP inserts the TEST frame with the specified flux, frame length, and transmission code type. The common and loopback test modes are supported.

Tab Name
Description
MD Configuration
An MD is a network or a part of a network for which Ethernet CFM is implemented. An MD is managed by a unified Internet service provider (ISP). An important attribute of the MD is level, which restricts the range of OAM operations. The MD can be embedded but not overlapped. Maintenance points process OAM packets according to the following rule: blocking OAM packets of lower levels, transparently transmitting OAM packets of higher levels, and processing OAM packets of the same level.
MA Configuration
An MA is a part of an MD. An MD can be divided into one or more MAs. The MA can be considered as a service-related domain, which consists of many MEPs.
MEP Configuration
An MEP is an edge node of an MA. The MEP, which is relevant to services, is the transmission and termination points of all OAM packets. The MEP has a unique MEP ID in the MA. On a network, the MA and MEP ID can uniquely identify an MEP.
RMEP Configuration
On a network where Ethernet CFM is running, the MEP on an NE is regarded as the local MEP, and the MEPs on the rest NEs in the same MA are regarded as RMEPs.
MIP Configuration
An MIP is an internal node of an MA. An MIP is created automatically and resides on an NE interface. MIPs are relevant to an MD, not an MA. MIPs cannot initiate OAM packets. Instead, they can respond to and forward LB/LT packets. They can forward CC packets only.

Ethernet OAM periodically sends CC packets to detect the service connectivity in real time. The source MEP constructs and sends CC frames periodically. After receiving the CC frames, the destination MEP enables the CC function. If the destination MEP does not receive the CC frames from the source MEP in a certain period of time (for example, 3.5 times the period for sending CC frames), a CCLOS alarm is generated. Step 8 Start the Ethernet OAM test. An Ethernet OAM test can be an LB, LT, LM, or DM test. These tests apply to links between CEs and PEs or between PEs. 1.

l The U2000 automatically enables the CC function during the running of LB, LT, LM, DM, and Test, and disables the CC function after the test is complete. l The U2000 allows you to select both the source and sink interfaces, right-click, and choose LB Test, LT Test, LM Test, or DM Test in ETH OAM Configuration View. l After you set filter criteria by specifying the source and sink interfaces, the U2000 determines whether an existing test path is available. If yes, you can start the LB/LT/LM/DM test directly. If no existing test path is available and the source and sink interfaces have been specified as filter criteria, a message is displayed asking you whether to allow the U2000 to automatically generate a test path. In addition to a test path, the U2000 also generates OAM configurations for the source and sink interfaces and starts the LB test. l You can select a PE or an LTE device as the sink NE. That is, the PE-CE LB/LT/LM/DM test is supported. An LTE device can act as a sink NE only. To carry out an LB test, you need to enter the OAM configurations of the LTE device, such as the sink NE, sink interface MAC address, and sink MEP ID. ----End
15.6 MPLS OAM Detection This topic describes how to configure MPLS OAM. OAM provides a sound fault detection and location mechanism and a powerful network performance monitoring function for tunnels on the MPLS network. The fault detection and location mechanism provides unidirectional and bidirectional tunnel continuity check and fault location. If a fault occurs in a tunnel, this mechanism rapidly triggers protection switching. The network performance monitoring function is used to detect and report performance events, such as packet loss, jitter, and delay for MPLS tunnels, thereby ensuring carrier-class service quality on the packet switched network.
Prerequisites IP tunnels and LDP tunnels do not support OAM configuration.
Context The process of MPLS OAM detection is as follows: Issue 03 (2014-05-15)

1.
The ingress node sends CV or FFD packets. The packets reach the egress node along the LSP that is to be detected.
2.
The egress node compares the type, frequency, TTSI, and other information in the received packets with the expected values locally recorded to determine whether the packets are correct. In addition, the egress node counts the number of correct and incorrect packets received in the specified measurement period to check the LSP connectivity.
3.
When detecting a defect in the LSP, the egress node analyzes the defect type and sends a BDI packet that carries the defect information to the ingress node using the reverse tunnel. The ingress node then learns the defect status in time. In this case, protection switching is triggered if a protection group has been properly configured.

Table 15-4 Parameters for configuring OAM Major Parameter
Settings
Detection Mode
Detection Packet Type and Detection Packet Period are available only when Detection Mode is set to Manual for the sink NE. l Auto-Sensing: The tunnel connectivity is tested using a userdefined frequency. l Manual: The tunnel connectivity is tested using the frequency of receiving packets.
Over Time
Indicates the OAM timeout period, namely, the period of waiting for the first detection packet after OAM configurations take effect. If the egress node does not receive any detection packet before the period expires, a defect is detected and BDI packets are triggered to alarm the ingress node.
Detection Packet Type
Indicates the type of OAM detection packets. MPLS OAM is implemented by periodically sending CV or FFD packets over the detected LSP. l FFD: short for fast failure detection. The detection frequency can be set. l CV: short for connectivity verification. The detection frequency is fixed and cannot be set. Example: Setting Detection Packet Type to FFD is recommended to ensure that the protection switching time is less than 50 ms.
SF Threshold
The SF threshold must be equal to or greater than the SD threshold.
BDI Frequency
BDI: short for backward defect indication. The frequency of sending BDI packets is the same as the frequency of sending OAM detection packets. The sink LSR of the downstream LSP uses a BDI packet to inform the source LSR of the upstream LSP of a defect along the reverse tunnel. This parameter indicates the frequency of sending BDI packets. Example: Setting this parameter to 10 is recommended.
Step 3 Click OK. Step 4 Optional: Select one or more tunnels, right-click, and choose OAM > Enable OAM from the shortcut menu to enable MPLS OAM. NOTE
Manually enabling OAM is not required because the U2000 enables OAM by default when you configure a tunnel protection group.
Step 5 Optional: Select one or more tunnels, right-click, and choose OAM > Clear OAM from the shortcut menu to clear MPLS OAM configurations. Issue 03 (2014-05-15)

NOTE
l Clearing OAM configurations is potentially service-affecting. Exercise caution when you perform this operation. l After OAM configurations are cleared, the switching function for static and static CR tunnel protection groups is unavailable. Because no OAM mechanism is available, the switching cannot be triggered even if the working tunnel is Down. l After OAM configurations are cleared, the protection switching speed of RSVP TE tunnels is slowed down. As a dynamic protocol-based detection mechanism is available for RSVP TE tunnels, the switching can still be performed in a speed lower than that in OAM detection.

15.7 Detecting MPLS-TP OAM The TP OAM function supports continuity check for IP services, achieving rapid service fault location and isolation.
Prerequisites l
You are an NMS user with "Maintenance Group" rights or higher.
l
Data synchronization must be performed for the related NE.
Background The U2000 automatically configures the PW switching point as an MIP for a multi-hop PWE3 service. You can view related configurations in the NE Explorer. TP OAM supports the following test methods: l
Loopback (LB): This method is used to test the connectivity between the local maintenance association end point (MEP) and the peer maintenance association intermediate point (MIP) or MEP.
l
Linktrace (LT): This method is used to test the connectivity between the local MEP and the peer MIP or MEP.
l
Loss measurement (LM): This method falls into near-end packet loss measurement that counts the packet loss ratio of the source node in the receiving direction and far-end packet loss measurement that counts the packet loss ratio of the source node in the sending direction.
l
Delay measurement (DM): This method is used to measure the delay of packets. Two types of DM methods are available: – One-way: The source node periodically sends OAM packets that carry timestamps. The sink node receives the packets, compares the receiving time with the timestamps, and works out the packet delay. – Two-way: The source node periodically sends DM request packets that carry timestamps. The sink node receives the packets and sends response packets that carry timestamps. The source node calculates the packet delay based on the timestamps.
l
Issue 03 (2014-05-15)
Test: This method is used for one-way on-demand diagnostic testing. When the test packet function is configured for testing, the MEP inserts the TEST frame with specified flux, frame length, and transmission code type. The following test types are available based on whether services are interrupted: Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

– Offline test (services interrupted): In this test, data service traffic is interrupted by the diagnosis entity. Generally, data services are moved to the backup path and an offline test is performed on the path. – Online test (services not interrupted): In this test, data service traffic is not interrupted by the diagnosis entity and frames with the TEST information are sent by using limited bandwidth. To perform an online test, ensure that data service traffic is not affected and the maximum transmission rate for frames with TEST information is restricted. Feature

NOTE
l When services are created for PTN NEs, the U2000 already configures related parameters for nodes. You need only to enable TP OAM. l For PWE3 services running on PTN, hybrid MSTP, or RTN series NEs, you can enable MPLS-TP OAM only after generic associated channel header label (GAL) is enabled or PW control words are configured. When a user attempts to enable MPLS-TP OAM, the U2000 automatically checks whether PW control words are configured for the PWE3 services. If control words are not configured, the U2000 automatically enables GAL.
l Alternatively, select a PWE3 service, right-click, and then choose PW OAM > Configure MPLS-TP OAM from the shortcut menu. In the dialog box that is displayed, set TP OAM check paths and parameters. NOTE

15.8 Configuration Example--Fault Diagnosis (RTN+CX) When a fault occurs on the network or network quality deteriorates, O&M engineers can use the U2000 fault diagnosis (RTN+CX) function to quickly locate the fault point. Then they can forward the fault information to the related O&M engineers to rectify the fault.
RTN+CX Scenario Description International carriers deploy CX NEs only at the core layer to achieve Layer 3 forwarding during the evolution to LTE. By doing this, they can use the existing RTN NEs instead of replacing them, reducing network construction costs. The RTN+CX solution has either of the following networking scenarios: l
Back-to-back networking
In a back-to-back networking scenario, native Ethernet services are created between RTN NEs and L3VPN services are created between CX NEs. l
Integrated networking
In an integrated networking scenario, PWE3 services are created between RTN and CX NEs.
Benefits The preceding networking scenarios cover the wireless, transport, and IP domains. O&M engineers are hard-pressed to understand all the related technologies. When a fault occurs on a cross-domain network, quickly locating the fault to determine the domain of the associated NE is the most important step in fault diagnosis.

16.1.2 Example for Configuring the RSVP TE Tunnel This topic provides an example for configuring the RSVP TE tunnel. Feature Summary l
During creation of an RSVP TE tunnel on the U2000, only the source and sink NEs must be selected. The U2000 obtains the working and protection paths from NEs and displays the paths on the topology view. After services are deployed, the working and protection paths are consistent with the previewed constraint paths.
l
If paths must be specifically planned, specify one or more NEs or ports to configure route constraint after the source and sink NEs are selected. The U2000 automatically recalculates available paths according to route constraint conditions and displays the available paths on the topology view. After services are deployed, the available paths are consistent with the previewed constraint paths.
l
The U2000 obtains path information from available NE paths. If the operations are correct, RSVP TE tunnels can be successfully deployed.

16.2.1 Examples for Configuring the ATM Service This topic provides an example for configuring the ATM emulation service. ATM transparent cell transport connects the traditional ATM network resources through a PSN, emulates the original service to the maximum on the PSN so that the end user does not realize the difference. In this way, it protects the settled investment of users and operators in the network consolidation and establishment.
16.2.1.1 Networking Configuration Diagram This topic describes the operation and maintenance scenario and provides the related networking diagram. On the existing access networks of carriers, the upstream equipment and downstream equipment of some earlier-deployed access equipment such as DSLAMs run ATM services. With the development of IP networks, the expandability, upgradeability, and compatibility of IP networks are greatly enhanced. Nevertheless, the flexibility of the upgrade, expansion, and interworking of traditional ATM networks is relatively poor. In addition, confined by transmission modes and service types, the sharing between traditional ATM networks and newly established networks is poor, leading to the difficulty in interworking management. Therefore, the traditional ATM networks need to be upgraded and expanded by fully utilizing the existing resources so that the traditional ATM networks can be combined with the current PSNs. ATM transparent cell transport can transmit services of an earlier ATM network over a PSN without adding new ATM equipment or changing the configuration of CEs on the ATM network. ATM transparent cell transport emulates ATM services on the PSN, which keeps end users from feeling the difference. In this manner, the investment of users and carriers can be protected in network consolidation and construction.

The implementation on the NMS is as follow: l
A PWE3 service with Service Type being ATM is configured on PE1 and PE2 to emulate the ATM service between CE1 and CE2.
l
The ATM interfaces of the two CEs are connected through a PW to implement ATM transparent cell transport. Thus, all ATM cells of one interface are transparently transmitted to the other interface through the ISP network without being processed or switched at the VPC or VCC layer.

On the backbone network, enable MPLS and LDP on PE1, P, PE2 and the related interfaces.
2.
Configure ATM interfaces and IPoA mappings on CEs.

16.2.2 Example for Configuring the CES Emulation Service This topic provides an example for configuring the CES emulation service.
16.2.2.1 Networking Configuration Diagram This topic describes the operation and maintenance scenario and provides the related networking diagram. The CES technology is used to transmit data in E1/T1 timeslots on an ATM network. The data is packed into ATM cells on the transmitting end, and then transmitted to the receiving end through the ATM network. On the receiving end, the data in the ATM cells are redistributed to E1/T1 timeslots. The CES technology guarantees that the data in E1/T1 timeslots can be restored to the original sequence on the receiving end. Multiple CESs such as PSTN services are run on the existing access networks of carriers. Those CESs need to be transmitted over ATM networks. With the development of IP networks, the expandability, upgradeability, and compatibility of IP networks are greatly enhanced. Nevertheless, the flexibility of the upgrade, expansion, and interworking of traditional ATM networks is relatively poor. In addition, confined by transmission modes and service types, the sharing between traditional ATM networks and newly established networks is poor, leading to the difficulty in interworking management. Therefore, the following solution is adopted to run the CES over PSNs. PWE3 is adopted to emulate the CES by carrying the frame format, alarm, signaling, and synchronous timing of TDM service data in the PWE3 packet header. After being encapsulated, the PWE3 packet is transmitted over the PSN. On the egress of the PW, the PWE3 packet is decapsulated, and the TDM circuit switching service flows are formed again.

16.2.4 Example for Configuring the ATM IWF Service This topic provides an example for configuring the ATM IWF emulation service.
16.2.4.1 Networking Configuration Diagram This topic describes the operation and maintenance scenario and provides the related networking diagram. On the existing access networks of carriers, the upstream equipment and downstream equipment of some earlier-deployed access equipment such as DSLAMs run ATM interfaces. With the development of IP networks, Ethernet is widely used and more and more Ethernet links are used at the core layer and the aggregation layer of the WAN. Therefore, the services of the ATM network need to be smoothly transferred to the Ethernet at the aggregation layer. The equipment on the ATM network needs to be interconnected with the BRAS on the Ethernet. In addition, the investment in the original ATM access equipment needs to be protected during the transfer. In the case that the original ATM access equipment is reserved, the ATM IWF technology is used to transparently transmit ATM cells to Ethernet links by adding certain intermediate equipment such as the NE40E. ATM IWF translates the VPIs and VCIs used to identify users on ATM links into VLAN IDs in the double VLAN tags of packets used on the Ethernet. That is, the VPI of the ATM traffic is mapped to the outer VLAN ID and the VCI is mapped to the inner VLAN ID. The BRAS identifies users according to VLAN IDs in the double tags of packets.

16.2.5 Example for Configuring the Heterogeneous Service This topic provides an example for configuring the heterogeneous emulation service.
16.2.5.1 Networking Configuration Diagram This topic describes the operation and maintenance scenario and provides the related networking diagram. A large number of Layer 2 services such as Ethernet, ATM, and CES services exist on the existing access networks of carriers. With the development of IP networks, the expandability, upgradeability, and compatibility of IP networks are greatly enhanced. Nevertheless, the flexibility of the upgrade, expansion, and interworking of traditional Layer 2 networks is relatively poor. In addition, confined by transmission modes and service types, the sharing between traditional Layer 2 networks and newly established networks is poor, leading to the difficulty in interworking management. In this case, you can configure PWE3 of heterogeneous media internetworking to implement interworking between Ethernet equipment and ATM equipment. NOTE
Currently, the U2000 supports the interworking only between Ethernet equipment and ATM equipment.

As shown in Figure 16-7, CE1 is connected to PE1 on the backbone network through ATM interfaces, and CE2 is connected to PE2 on the backbone network through GE interfaces. It is required that heterogeneous media internetworking should be configured to transparently transmit service data between CE1 and CE2. The implementation on the NMS is as follow: l
A PWE3 service with Service Type being Interworking is configured on PE1 and PE2 to implement interworking between Ethernet equipment and ATM equipment.
l
PVCs need to be created on the AC interfaces of the ATM type, and the IPoA mappings need to be configured on the PVCs.

16.3.3 Example for Configuring Daisy Chain Networking This topic describes how to configure a VPLS service in daisy chain networking mode.
16.3.3.1 Configuration Networking This topic describes the operation and maintenance scenario and provides the related networking diagram. The daisy chain networking is a type of networking used for BTV multicast services in the Huawei solution. In daisy chain networking, a dynamic spoke PW is established between UPEs, a dynamic mesh PW is established between a PE-AGG or PE on the upper-layer network and the UPE that is connected to the PE-AGG or PE, but no PW is established between PE-AGGs or PEs. In this manner, the equipment on the border between the Metro Ethernet and the upperlayer network is linked by PWs like a chain. Thus, this networking is called the daisy chain. The common deployment mode is to deploy the VPLS of the daisy chain type to the position shown in the following figure. Note that the access network can consist different types of equipment. The PE-AGGs or PEs on the upper-layer network connect to UPEs. Generally, the interface that connects a PE-AGG to the Metro Ethernet runs IGMP and PIM. Two PE-AAGs or PEs exchange PIM Hello packets over the daisy chain on the Metro Ethernet.

16.5 Example for Configuring Composite Services This topic describes the networking modes and configuration methods for composite services with examples.
16.5.1 Example for Configuring the PWE3+VPLS Composite Service This topic describes the networking application and configuration method of the PWE3+VPLS composite service with an example.
16.5.1.1 Configuration Networking Diagram This topic describes the networking diagram of the PWE3+VPLS composite service. Figure 16-15 shows the typical network diagram of configuring the PWE3+VPLS composite service on the Metro Ethernet. The PWE3 service is configured on the UPEs and the SPEs, and the VPLS service is configured on SPEs. The UPEs add double MPLS labels to the packets sent by the CEs. The outer layer is the LSP label and is switched when a packet passes through the devices on the access network. The inner label is the VC label that identifies the VC. The inner label remains unchanged when a packet is transmitted along the LSP. The packets received by the SPEs contain double labels. The outer label, which is a public network label, is popped up. The inner label decides which VSI the PWE3 accesses.

16.5.2 Example for Configuring the PWE3+L3VPN Composite Service This topic describes the networking application and configuration method of the PWE3+L3VPN composite service with an example.
16.5.2.1 Configuration Networking Diagram This topic describes the networking diagram for configuring the PWE3+L3VPN composite service. Using an L2VPN, users can access L3VPN services running on an access network or bearer network. This reduces the user information that is maintained by access devices. Therefore, the low-end devices can be deployed in the access network, reducing the networking cost. For users, the access network is transparent, and users seem to connect to the public network or L3VPN directly. This makes the networking more flexible. As shown in Figure 16-16, the NPE and PE2 function as PEs of the IP/MPLS backbone network. The UPE functions as the PE of the PWE3 access network. CE1 accesses the MPLS L3VPN of the IP/MPLS backbone network through the PWE3 network, and communicates with CE2. VE 2/0/0 and VE 2/0/1 are created on the NPE. VE 2/0/0 is an L2VE interface used to terminate PWE3 services, and VE 2/0/1 is an L3VE interface used to access the L3VPN.

16.5.3.1 Configuration Networking Diagram This topic describes the networking diagram for configuring the VPLS+L3VPN composite service. Using an L2VPN, users can access L3VPN services running on an access network or bearer network. This reduces the user information that is maintained by access devices. Therefore, the low-end devices can be deployed in the access network, reducing the networking cost. For users, the access network is transparent, and users seem to connect to the public network or L3VPN directly. This makes the networking more flexible. A user has many scattered sites on the same access network of a carrier, and the scattered sites are connected through Ethernet. These sites need to be interconnected to form an integrated network. In this case, the VPLS can be deployed on the access network to connect those sites of the user and access the MPLS L3VPN service running on the bearer network. If there are many scattered sites on the access network, deploy HVPLS on the access network. Configure the NPEs as upper-layer PEs and UPEs as lower-layer PEs. Therefore, the logical connections between PEs are reduced. As shown in Figure 16-17, the NPE and PE3 serve as the PE of the IP/MPLS backbone network; UPE 1 and UPE 2 serve as the UPE of the VPLS access network. LDP is used as the signaling protocol between UPE 1, UPE 2, and the NPE to set up HVPLS. CE1 and CE2 access the MPLS L3VPN on the IP/MPLS backbone network through the VPLS network, and communicate with CE3. Create VE 2/0/0 and VE 2/0/1 on the NPE. The VE 2/0/0 is the L2VE interface to terminate the VPLS, and the VE 2/0/1 is the L3VE interface to access the L3VPN.

16.5.4 Example for Configuring the Inter-AS PWE3-OptionA Composite Service This topic describes the networking application and configuration method of the inter-AS PWE3OptionA composite service.
16.5.4.1 Configuration Networking Diagram This topic describes the networking diagram for configuring the inter-AS PWE3-OptionA composite service. As a basic VPN application in the inter-AS scenario, inter-AS VPN-OptionA does not need to be configured specially. In inter-AS VPN-OptionA mode, the ASBRs of two ASs are directly connected and function as PEs in the ASs. Thus, the ASBRs are called ASBR PEs. Either of the ASBR PEs takes the peer ASBR as its CE and advertises IPv4 routes to the peer ASBR PE through EBGP. If the number of VPNs that access PEs and the number of VPN routes are both small, inter-AS PWE3-OptionA can be adopted. In inter-AS PWE3-OptionA, ASBRs in the AS must support VPN instances and must be capable of managing VPN routes. In addition, ASBRs must reserve dedicated interfaces including subinterfaces, physical interfaces, and bound logical interfaces for each inter-AS VPN. That is, inter-AS PWE3-OptionA poses high requirements of ASBRs; however, for inter-AS networking, ASBRs do not need any special configurations.

As shown in Figure 16-18, the ASBRs of the two ASs are directly connected. The ASBRs are the PEs of their respective ASs. The two ASBRs regard the peer ASBRs as their CEs. PWE3 services are deployed in two ASs. The VPN user is connected to AS100 and AS200. User data is transmitted through special interfaces between ASBRs. The user exclusively occupies the link between the ASBRs.
16.5.4.2 Service Planning This topic describes the data planning of the inter-AS PWE3-OptionA networking. The configuration roadmap is as follows: l
Configure related routing protocols on the backbone network to implement interworking. That is, configure an IGP in an AS and BGP on ASBRs.
l
Configure basic MPLS functions on the backbone network, and establish dynamic LSPs between PEs and the ASBR in the same AS. If the PEs and ASBR are not directly connected, set up remote LDP sessions.
l
Set up PWE3 connections between PEs and the ASBR in the same AS.
l
Configure connection points to combine the PWE3 services of the two ASs into a composite service.

Either of the ASBR PEs takes the peer ASBR as its CE and advertises IPv4 routes to the peer ASBR PE through EBGP. As shown in Figure 16-19, VPLS services are deployed in two ASs. The VPN user is connected to AS100 and AS200. The packets are transmitted through special interfaces between ASBRs. The user exclusively occupies the link between the ASBRs.

As a basic L3VPN application in the inter-AS scenario, inter-AS VPN-OptionA does not need to be configured specially. In inter-AS VPN-OptionA mode, the ASBRs of two ASs are directly connected and function as PEs in the ASs. Thus, the ASBRs are called ASBR PEs. Either of the ASBR PEs takes the peer ASBR as its CE and advertises IPv4 routes to the peer ASBR PE through EBGP. An ASBR PE needs to manage all VPN routes in an AS and create a VPN instance for each VPN. Therefore, inter-AS L3VPN-OptionA is applicable in the scenario where the number of inter-AS VPNs is small.

17.1.1.1 Networking Diagram This topic describes the O&M scenario and networking diagram of a static CR tunnel. As shown in Figure 17-1, the service between NodeB and RNC is to be carried by a static CR tunnel. NE1 accesses the service from NodeB. The service is then transmitted to the 10GE ring at the convergence layer through the GE ring at the access layer. Finally, the service is converged at NE3 and transmitted to the RNC. If the service requires high network security, configure MPLS APS protection to ensure service transmission. l
Working tunnel: NE1-NE2-NE3. NE2 is a transit node.
l
Protection tunnel: NE1-NE6-NE5-NE4-NE3. NE6, NE5, and NE4 are transit nodes. If the working tunnel becomes faulty, the service in this tunnel is switched to the protection tunnel.

17.1.2 Example for Configuring an RSVP TE Tunnel This topic provides an example for configuring a static RSVP TE tunnel.
17.1.2.1 Networking Diagram This topic describes the O&M scenario and networking diagram of a static RSVP TE tunnel. As shown in Figure 17-3, company A has branches in City 1 and City 2. Services between the branches must be transmitted in real time, which requires creation of a tunnel for carrying the services. Real-time services impose a high requirement on network security. Hence, FRR protection needs to be configured for the MPLS tunnel between NE1 and NE3. l
The working tunnel from NE1 to NE3 is along the NE1-NE2-NE3 trail. NE2 is a transit node on the trail.
l
Bypass tunnel 1 from NE1 to NE3 is along the NE1-NE4-NE3 trail. If NE2 or the link between NE1 and NE2 is not functioning properly, bypass tunnel 1 protects the working tunnel.
l
Bypass tunnel 2 from NE2 to NE3 is along the NE2-NE4-NE3 trail. If the link between NE2 and NE3 is not functioning properly, bypass tunnel 2 protects the working tunnel.

Bypass tunnel 1 and bypass tunnel 2 provide FRR protection for the working tunnel. On the NNI side of the NEs, GE boards are used for service transmission and a GE ring is formed on the boards. Assume that the port IP addresses of NEs are automatically assigned. The IP addresses are listed as follows. Issue 03 (2014-05-15)

Since the service bandwidth is 10 Mbit/s, the bypass tunnel must have bandwidth higher than 10 Mbit/s. The service passes through multiple NEs; therefore, multiple bypass tunnels must exist to protect the working tunnel. Based on the actual situation, two bypass tunnels are planned for FRR. Table 17-5 lists the parameters planned for one working tunnel and two bypass tunnels. Table 17-5 Planning of tunnel parameters

17.2 Examples for Configuring a PWE3 Service This topic provides several examples for configuring a PWE3 service in typical networking modes.
17.2.1 Example for Configuring an End-to-End IP over PW Service This topic provides an example for configuring an end-to-end IP over PW service and provides a flowchart to illustrate the service configuration process.
17.2.1.1 Example Description This topic describes the function requirement, networking diagram, and service planning of an example.
Requirement and Networking Diagram The IP over PW solution needs to be used to achieve IP access based on the capabilities of the access equipment at the edge of a PTN network. Figure 17-6 shows the deployment of an IP over PW service. NE1 is an OptiX PTN 1900 NE and NE2 is an OptiX PTN 3900 NE. A Layer 3 virtual port needs to be created on NE2, and this port serves as the sink port for the IP over PW service. A VRF needs to be configured on NE2. The IP over PW service corresponds to a VRF UNI on NE2. This UNI serves as one VRF UNI on NE2. Port 1-EG16-2 on NE2, which is directly connected to the RNC, needs to be configured as another VRF UNI.

NOTE
A VRF instance synchronizes route information. NE2 does not store the IP address of NodeB (the IP over PW service is static and no protocol synchronizes routes), and therefore the DIP with the packets sent to the RNC is the IP address of NodeB. To ensure that the packets are sent from the RNC to NodeB, the IP address of the UNI on NE2 and the port IP address of the NodeB must be in the same network segment. Note that a NodeB may have two IP addresses, that is, service IP address and port IP address. The IP address of the Layer 3 virtual port and the IP address of NodeB must be in the same network segment. NOTE
Service configuration on the OptiX PTN 3900-8 is the same as that on the OptiX PTN 3900, except for the slots for service boards. For details about service configuration on the OptiX PTN 3900-8, see this example about service configuration on the OptiX PTN 3900.

NOTE
A static CR tunnel is based on certain constraints, which are established and managed using the CR mechanism. Unlike a static tunnel, a static CR tunnel can be created when the routing information is available and certain constraints, such as specified bandwidth, selected path, and QoS parameters, are met. If you set Signaling Type to Static CR, you can select Create Reverse Tunnel. If you set Signaling Type to RSVP TE, you can set Template to copy tunnel details from a template.
l In this example, select only Create Reverse Tunnel. If you select Create Reverse Tunnel, a forward tunnel and a reverse tunnel are created. Otherwise, only a forward tunnel is created. If you select Create Bidirectional Tunnel, a bidirectional tunnel is created. If you select Create Protection, a protection tunnel is also created.

17.2.3 Example for Configuring an ATM Service This topic provides an example for configuring an ATM service.
17.2.3.1 Example Description This topic describes O&M scenarios and networking diagrams. Figure 17-9 shows the networking diagram of ATM services. The 3G R99, signaling, and HSDPA services are required between the two base stations and RNC. NE1 accesses the MPLS network that consists of PTN equipment. NodeB1 is connected to NE1 through IMA1, and NodeB2 is connected to NE1 through IMA2. VPI/VCI switching is performed on NE1, and VPI/ VCI transparent transmission is performed on NE2 and NE3. Between NE1 and NE3, three PWs are used to carry the R99, signaling, and HSDPA services respectively. At the remote end, NE2 is connected to RNC through STM-1 to transparently transmit the ATM services on the MPLS network.NE1 is an OptiX PTN 1900 NE; NE2, NE3, NE4, and NE5 are OptiX PTN 3900 NEs; NE6 is an OptiX PTN 950 NE. ATM services are carried in the active tunnel. You can create a bypass tunnel to protect real-time services. The active tunnel is NE1-NE2-NE3. The bypass tunnel is NE1-NE6-NE5-NE4-NE3.

Between NE1 and NE3, PW1 transmits R99 services, PW2 transmits HSDPA services, and PW3 transmits signaling services. Therefore, you need to create three ATM services. The two base stations converge R99 services and access signaling and HSDPA services. Therefore, you need to create two ATM services connected to the N:1 VCC. Assume that the IP addresses of the ports on NEs are the same as those listed in Table 17-39 after the U2000 automatically allocates port IP addresses. Table 17-37 NE parameters NE

17.2.4 Example for Configuring an ETH Service This topic provides an example for configuring an ETH service.
17.2.4.1 Example Description This topic describes O&M scenarios and networking diagrams. As shown in Figure 17-11, company A and company B have branches in city 1 and city 2. Branches of each company need to communicate with each other. Services from the two companies must be isolated. NE1 is connected to company A and company B in city 1 and NE3 is connected to company A and company B in city 2. NE1 accesses services from city 1, NE2 transparently transmits the services, and NE3 transmits the services to city 2. Similarly, NE3 accesses services from city 2, NE2 transparently transmits the services, and NE1 transmits the services to city 1. You can configure Ethernet private line services to meet the requirements of communication between the branches of company A and between the branches of company B. Two PWs carry the services of company A and company B respectively and share bandwidth of a same tunnel. In the case of company A, the branches require the common Internet access service, CIR = 10 Mbit/s, PIR = 30 Mbit/s, VLAN ID = 100. In the case of company B, the branches require the data service, CIR = 30 Mbit/s, PIR = 50 Mbit/ s, VLAN ID = 200. NE1 is an OptiX PTN 1900 NE; NE2 and NE3 are OptiX PTN 3900 NEs.

17.3 Example for Configuring a VPLS Service This topic provides an example for configuring a VPLS service.
17.3.1 Example for Configuring the Full-Mesh Networking 17.3.1.1 Networking Diagram This topic describes the O&M scenario and networking diagram of a VPLS service. As shown in Figure 17-12, the three CE networks need communicate with each other. Each CE network VPLS service has the same VLAN value, that is, 100. MPLS tunnel 1, MPLS tunnel 2, and MPLS tunnel 3 exist among the three PEs. Among the CE networks, three types of services, including the voice service, data service, and common Internet access service, are available. Complex traffic classification can be performed on the access side, and different QoS policies for assured bandwidth can be configured. The network can prevent multicast storms.

17.3.2 Example for Configuring the Hub-Spoke Networking This topic uses an example to describe how to configure hub-spoke VPLS services. Feature Summary If multiple devices are located on the ring networks on a site and multicast and unicast services have been deployed for the devices, a tunnel exists between any two adjacent devices on a ring. The tunnel can be used to support multicast and unicast services on Hub-Spoke networks. If multi-hop PWs are not supported during creation of a unicast service between nodes on two rings, you must create a multi-hop tunnel to bear PWs between the nodes. This leads to a waste of tunnel resources. During creation of a Hub-Spoke VPLS service, you can create multi-hop PWs between NEs to reuse the tunnels that have been created on adjacent NEs on a created ring for multicast services to complete unicast services. NOTE
PTN6900s currently do not support this function.
17.3.2.1 Networking Diagram This topic describes the O&M scenario and provides the related networking diagram. The following figure shows an access ring formed by five PTN NEs. NE (57-29) is the intersecting node of the aggregation and access rings. VPLS service data passing through NE (57-29) are sent to four other nodes using unicast paths. The following describes all NE roles in VPLS services in an access ring as well as the tunnels to be created. l
NE (57-29) is the NPE node, and four other NEs are UPE nodes.

17.5.2 Example for Configuring a PWE3+PWE3 Composite Service This topic provides an example for configuring a PWE3+PWE3 composite service.
17.5.2.1 Configuration Networking Diagram This topic describes O&M scenarios and networking diagrams. In this scenario, protection for the services between rings is enhanced. Fibers in each section of a service are protected, so that the service is well protected. For example, a PWE3 service between PE1 and PE4 can be divided into three sections, as shown in Figure 17-19. PW APS protection is configured for the sections from PE1 to PE2 and from PE3 to PE4 and LAG protection is configured for the section from PE2 to PE3. In this way, each fiber has its protection link in each section of the service and therefore the protection capability of the PWE3 service is enhanced.

17.6.1 Configuration Networking Diagram This topic describes an example of dual-homing protection with NNI-site 1:1 MC-PW APS and AC-side MC-LAG, and focus on the function requirement, and networking diagram. An E-Line service from NodeB needs to be transported to RNC over the PTN network. NodeB carries services over FE interfaces and RNC carries services over an SC-LAG. Dual-homing protection must be provided on the RNC side for the services from NodeB. As shown in Figure 17-20, the OptiX PTN 950 is deployed on PE3, which accesses the E-Line services from NodeB through FE interfaces. To provide dual-homing protection for the services on the RNC side, PE1, PE2, and RNC are connected in dual-homing mode. The equipment that supports PW APS and MC-LAG is deployed on PE1 and PE2, each of which accesses E-Line services through an LAG.

17.7 Configuration Case of VRRP This topic describes a configuration case of VRRP, involving a configuration network diagram, service planning, and configuration process.
17.7.1 Configuration Networking Diagram This section describes the requirements, and network diagram. As shown in Figure 17-21, NE1 and NE2 form a VRRP VR to protect the RNC. The requirements of VRRP are as follows: l
NE1 works as the master of the VRRP VR. When NE1 is faulty, NE2 becomes the master.
l
BFD sessions need to be configured at interfaces on NE1 and NE2 to monitor both NE1 and link NE1-RNC-NE2. Therefore, when NE1 is faulty or link NE1-RNC is faulty, the master/backup switching is performed within one second.
l
After NE1 is restored, it becomes the master within 20 seconds. Preemption is enabled for NE1. That is, NE1 preempts NE2 5 seconds after NE1 is restored.
l
To avoid attacks on the network, you must configure VRRP packet authentication.

18.2.1.3 Configuration Process This topic describes how to configure a CES emulation service.
Prerequisites l
You are an NMS user with "Maintenance Group" authority or higher.
l
The network structure, networking requirements, and service planning in the example must be obtained.
l
A network must be created.
l
Tunnel 2 exists between NE1 and NE3 and tunnel 1 exists between NE2 and NE3.
Context If an interface is used to carry the CES service, you need to configure the frame format to be same as the service encapsulation format. If the emulation mode of a CES service is CESoPSN, it is recommended that you set the frame format of the interface to CRC-4 Multiframe. If the emulation mode of a CES service is SAToP, the frame format of the interface must be set to Unframe. If a UNI is used to carry the CES service, you need to configure the frame mode. Frame Mode of the PDH port packets of the RTN supports 30 and 31 timeslots. In a mixed networking scenario, ensure that the frame mode of the local port is the same as that of the peer port. l
30 timeslots: The 1-15 and 17-31 timeslots in the E1 frame format are used to transmit service data.
l
31 timeslots: The 31 timeslots in the E1 frame format are used to transmit service data.
Procedure Step 1 This section describes how to set the LSR ID for each NE. Issue 03 (2014-05-15)

This parameter indicates the timeslot compression list for structured CES emulation services. Services are loaded in the timeslots that are included in the timeslot compression list, encapsulated into PW packets, and transmitted to the peer end on an Ethernet. Services loaded in the timeslots that are not included in the timeslot compression list are not encapsulated into PW packets and therefore the network bandwidth is saved. After receiving the PW packets, the peer end restores the services to the corresponding timeslot based on its own timeslot compression list. The timeslot lists at the two ends can be different, but the number of timeslots must be the same. Otherwise, services are unavailable.

Procedure Step 1 Configure NNIs. 1.
In the NE Explorer of NE1, choose Configuration > Packet Configuration > Interface Management > Ethernet Interface from the Function Tree.
2.
On the General Attributes tab page, select 3-N1PEG16-1(Port-1) and 3-N1PEG16-2 (Port-1). Right-click the Port Mode field and choose Layer 3. Set parameters as needed and click Apply.
NOTE
l Enable Port is set to Enabled. l When Port Mode is set to Layer 2, Encapsulation Type can be set to Null, 802.1Q, or QinQ. l When Port Mode is set to Layer 3, Encapsulation Type can be set to 802.1Q, and the interface can be used by a tunnel. l The Auto-Negotiation working mode is recommended. If the working mode of the port is set to any other mode instead of Auto-Negotiation, the working mode of the interconnected port must be the same. Otherwise, the communication fails. l Max Frame Length (byte) for an NNI must be greater than 960 because the maximum length of DCN packets is 960. If Max Frame Length (byte) is smaller than 960, DCN packets may be lost in the receive direction.
3.
Select 3-N1PEG16-1(Port-1) and 3-N1PEG16-2(Port-2) on the Layer 3 Attributes tab page. Right-click the Enable Tunnel field and choose Enabled from the shortcut menu.

On the network, the E-LAN services are carried by PWs. Hence, you need to plan the parameters related to the PWs and the MPLS tunnel. Planning of the E-LAN services carried by PWs involves the following operations: l
Plan the tunnel carrying PWs. For details, see Table 19-21.
l
Plan the E-LAN services carried by PWs. For details, see Table 19-22.
l
Plan the UNI of each NE. For details, see Table 19-23.
l
Plan the PW on the NNI of each NE. For details, see Table 19-24. NOTE
You can set one split horizon group for each E-LAN service. You need to configure the NNI of each PE node with a split horizon group to prevent the data from being forwarded between the UNIs so as to prevent broadcast storms. You can set the unknown frames to be broadcast.

20.1 Example for Configuring the SDH+PWE3 Composite Service This topic describes the networking application and configuration method of the SDH+PWE3 composite service with an example.
20.1.1 Networking Configuration This topic describes an SDH+PWE3 networking scenario. Figure 20-1 shows that an E1 service enters the network on the customer side of an SDH network, passes through an SDH network and a PWE3 network, and leaves the network on the customer side of the PWE3 network. l
NE1 accesses the E1 service on the base transceiver station (BTS) or Node B using a tributary board and encapsulates the E1 service as a VC12 service. The VC12 service is transported to a line board using SDH trails and further forwarded.
l
NE3 uses SDH trails to forward the VC12 service to NE5 in synchronous transport mode 1 (STM-1) without processing the VC12 service.
l
NE5 directly performs PW encapsulation for the VC12 service and transmits the VC12 service to NE7 using tunnels.
l
NE7 decapsulates the VC12 service and sends it to the Base Station Controller (BSC) or radio network controller (RNC).
NE1 is an Metro 1000. NE3 is an OSN3500. NE5 is an OptiX PTN 1900. NE6, NE7, and NE8 are OptiX PTN 3900s. NE3 connects to NE5 by a fiber. Customers are interested in using the to interconnect the SDH and PWE3 for forming an SDH +PWE3 service and to monitor and manage such a service in centralized mode.

The HUNS3 board is used to process packets or VC-4 signals and then encapsulate processed packets or signals into ODUk signals. After being reused and mapped, the ODUk signals are converted to the OTUk optical signals with the wavelength complying with the WDM system. The OTUk optical signals are then transmitted on the OTN. In this manner, the packet service or SDH service is transferred to WDM lines for transmission. The HUNS3 board converts the packet service signals to OTU3/OTU3e signals on one channel. OTU3/OTU3e signals are standard DWDM wavelengths complying with ITU-T G.694.1. The HUNS3 board supports the unified transmission of SDH and packet services with a maximum of 40 Gbit/s. The EG16 board can be used to create a PWE3 Ethernet service.
Board Configuration In this example, two HUNS3 boards and an EG16 board are configured for both NE(9-140) and NE(9-142).

FAQ
Automatic Service Discovery l
Q: After service deployment is complete using commands, the U2000 cannot be synchronized. A: In addition to NE data synchronization, you must perform the following operations to perform automatic service discovery on the U2000 service management page:
l
1.
Select an NE, right-click, and choose Synchronize NE Data from the shortcut menu.
2.
Choose Service > Search for Service (traditional style) from the main menu or select Bearer Network Service Configuration in Application Center and choose Service > Search for Service (application style) from the main menu.
Q: U2000 A discovers N discrete tunnels during automatic tunnel discovery. These tunnels, however, are displayed as normal tunnels on U2000 B. A: This problem may occur during automatic tunnel discovery after tunnels are bound to rings. You can perform the automatic discovery of MPLS protection rings first and then the automatic discovery of tunnels to address the problem. The order of automatically discovering services is the same as that of the network layer at which services reside, from bottom to top. The U2000 automatically discovers services in the following order: MPLS protection ring>Tunnel>PWE3/VPLS/L3VPN.
l
Q: Why does the U2000 fail to automatically discover PWE3 services for PTN NEs? A: For details about the solution, see Q: After service deployment is complete using commands, the U2000 cannot be synchronized..
Running Status for a Service Is Partially Down l
Q: How do I resolve the issue that Running Status for a tunnel service is Partially Down? A: The possible cause is the status inconsistency between the U2000 and NE or the failure of interfaces or NEs on some hops of the tunnel. To resolve this issue, right-click the service and choose Refresh Running Status from the shortcut menu. If Running Status is still Partially Down, access the NE Explorer and check the NE and interface status of each hop on the tunnel.

Q: How do I resolve the issue that Running Status for a VPN service is Partially Down? Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.
869
iManager U2000 Unified Network Management System Operation Guide for IP Service Management
22 FAQ
A: A VPN service comprises multiple components such as NEs and SAIs. The running status of the VPN service is Up only when all the components are in the Up state. If some components are in the Down state, running status of the VPN service is Down. You can view the running status of components in the service topology. Components marked red are in the Down.
Running Status for a Service Is -l
Q: What is the meaning of Running Status displayed as -- for a tunnel or VPN? A: If Running Status is displayed as --, services are not deployed to the device and the U2000 does not detect the service status, or services are deployed to the device but the device does not support this parameter.
l
Q: How do I solve the issue that Running Status for a tunnel or VPN is --? A: View the deployment status of the tunnel or VPN. – If Deployment Status is displayed as Deployed, the device doe not support Running Status and no action is required. – If Deployment Status is displayed as Undeployed, check the associated parameters according to service planning and then deploy the configurations. The following uses the PWE3 service as an example to describe how to deploy configurations. 1.
Choose Service > PWE3 Service > Manage PWE3 Service (traditional style) from the main menu or select Bearer Network Service Configuration in Application Center and choose Service > PWE3 Service > Manage PWE3 Service (application style) from the main menu.
2.
On the Manage PWE3 Service page, select the service to be deployed.
3.
Right-click the selected service and choose Deploy from the shortcut menu.
Importing and Exporting Service Data Q: The function for importing and exporting service data cannot be used on the U2000. How do I resolve this problem? A: You must buy the corresponding license before using this function. For details, see iManager U2000 License Instructions.
Creating Tunnel 1.
Q: Tunnels cannot be configured after fiber synchronization. How do I resolve this problem? A: On the U2000, tunnels are created based on Layer 2 links instead of fibers. When the U2000 searches for Layer 2 links, all links are traversed. If UNI-UNI Layer 2 links exist, the problem occurs. To resolve the problem, delete the UNI-UNI Layer 2 links.
2.
Q: When I select PTN NEs during tunnel creation, a message is displayed on the U2000 indicating that tunnel creation is not supported. How do I resolve this problem? A: Restart the U2000 process. Open a System Monitor client. Select the process with Service as NML_IP, right-click, and choose Start the Process from the shortcut menu.

Q: The tunnel ID range is incorrect when Protocol Type is set to IP for a newly created tunnel. The tunnel ID range is 1 to 1024 on the U2000; however, devices support the tunnel ID range from 1 to 256. How to address the problem? Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.
870
iManager U2000 Unified Network Management System Operation Guide for IP Service Management
22 FAQ
A: When Protocol Type is set to IP for a newly created tunnel, the tunnel ID range is closely related to the NE, version, and board. Different NEs, versions, and boards support different tunnel ID ranges. Therefore, the tunnel ID ranges for different boards on the same device differ. The U2000 displays the tunnel ID range only based on the device. Currently, you can only view the error message to address the problem. 4.
Q: What is the definition of an idle tunnel? Is the standby tunnel in a protection group carrying no service regarded to be an idle tunnel? A: A tunnel in an APS protection group is not an idle tunnel. The idle tunnel is the one that carries no service and is not in any protection group.
5.
Q: Why is a known tunnel alarm not displayed in the alarm list on the tunnel management page? A: Alarm correlation applies to only the unacknowledged, acknowledged, and cleared alarms.
6.
Q: Why do the reverse and forward tunnels automatically generated by the U2000 have the same name during tunnel creation? A: The name of a reverse and forward tunnel contains a maximum of 64 characters. If the tunnel name contains more than 64 characters, only the first 64 characters are displayed when the service name is generated. To address this problem, choose Administrations > Settings > Naming Define Rule from the main menu to reset the naming rule for tunnels.
7.
Q: A user sets Signaling Type to Static or Static CR during creation or copying of a tunnel. After the user selects the Auto-Calculate route check box and selects the source and sink NEs, the message No route available is displayed. How do I address this problem? A: Check whether a Layer link is correctly configured between NEs. A Layer 2 link forms a basis for automatic route calculation. You can check whether a Layer 2 link exists between NEs in the topology or by choosing Inventory > Link Management from the main menu.
Creating MPLS Protection Ring 1.
Q: Why is no available NE displayed after I click Add for creating an MPLS protection ring? A: MPLS protection rings can be created only for the PTN V100R003C02 and later. If the PTN is not managed by the U2000, no NE needs to be added when you create an MPLS protection.
2.
Q: After NEs are added one by one to create an MPLS protection ring, only some of the eastbound and westbound interfaces on the NEs are automatically displayed. What is the reason for the problem? How to deal with the problem? A: The U2000 automatically calculates the eastbound and westbound interfaces on NEs only when Layer 2 links exist between the NEs. If some interfaces are not automatically displayed, configure Layer 2 links between NEs and select eastbound and westbound interfaces.
3.
Q: Are OAM and APS enabled by default for an MPLS protection ring? Are there any constraints for the OAM EXP and ring EXP values? A: OAM and APS are enabled by default when you create an MPLS protection ring. There are not any constraints for the OAM EXP and ring EXP values because the OAM EXP and ring EXP are independent of each other.

Q: If an APS protection group has been configured for a tunnel before the tunnel is bound to an MPLS protection ring, how to invalidate APS and enable the tunnel to use protection provided by the MPLS protection ring? A: a.
In the dialog box that is displayed after a tunnel is bound to an MPLS protection ring, click Modify Protection Group. The Manage Protection Group window is displayed and APS protection groups relevant to the tunnel are filtered out.
b.
the Modify Protection Group dialog box is displayed. In this dialog box, modify Hold-off Time.
c.
Change the value to be the same as the value of Hold-off Time set for the MPLS protection ring to which the tunnel is bound.
In addition, 5.
Q: Why does alarm generation fail for some tunnels after the tunnels are bound to an MPLS protection ring and the ingress and egress nodes on the ring are isolated nodes? A: As OAM is not enabled during tunnel configuration, MPLS protection ring faults cannot be detected, which leads to the alarm generation failure. You are advised to enable OAM after tunnel creation.
MPLS Protection Ring Management Q: Why does an MPLS protection ring with two NEs and that with three NEs have a virtual intersection point in the topology on the Intersecting MPLS Ring tab in the Manage MPLS Protection Ring window?
A: After an intersection point is configured for two MPLS protection rings that have three NEs deployed respectively, if a non-intersection NE on one of the MPLS protection rings is deleted, a virtual intersection point exists between the MPLS protection ring with two NEs and that with three NEs, as shown in the preceding figure.
Creating PWE3 Service Q: I import the NEs configured with PWE3 services to the U2000 using a template. Why are these PWE3 services not displayed on the U2000? Issue 03 (2014-05-15)
Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

iManager U2000 Unified Network Management System Operation Guide for IP Service Management
22 FAQ
A: After you import the NEs to the U2000, you need to synchronize the NE information and discover IP services before the U2000 displays these PWE3 services. For details, see 6.1 Automatically Discovering Single IP Services.
PWE3 Test Q: Why is the VCCV test of the PWE3 service on PTN NEs failed? A: PTN NEs are not configured with a dynamic routing protocol. Different routes result in a failure to establish LDP peers or display LDP peer information. Therefore, the tests associated with the LDP peer all fail.
L3VPN Deployment Q: Why is the message Failed to run the command. The VTY privilege level of the NE or the parameter settings of the command may be incorrect. or Failed to log in to the device. Check the settings of the user name, password, key, and device Telnet parameters and whether the test is successful. displayed during L3VPN service deployment? A: If the U2000 is used to configure the L3VPN service on NEs, you must ensure that the Telnet/ Stelnet parameters are configured properly. For the detailed description about the Choose Administration > NE Communicate Parameter > NE Telnet/STelnet Template Management (traditional style) from the main menu or select Fix-Network NE Configuration in Application Center and choose Administration > NE Communicate Parameter > NE Telnet/STelnet Template Management (application style) from the main menu., press F1 on the U2000 GUI to view the Help.
L3VPN Service Modification Q: Why does the U2000 fail to respond for a comparatively long period of time when I modify L3VPN service data? A: Two problems have been found. l
To add a UPE, the user needs to modify the entire L3VPN service. All the related UPEs, SPEs, and NPEs need to be loaded in the modification window, which involves a large volume of data and slows down the response speed. It takes about two minutes to open the window. Solution: To add a node or SAI, click Create or Fast Add on the VRF or SAI tab to quickly modify service settings.
l
Multiple SAIs that alternate between Up and Down exist on the NE, resulting in the frequent reporting of the L3VPN Down alarm. An NE reports an alarm in every 10 seconds. An ATN NE has reported as many as 16,000 L3VPN Down alarms. After receiving an SAI Down or L3VPN Down alarm, the U2000 notifies the service module to refresh L3VPN service status. When so many intermittent alarms are frequently reported, the U2000 background is busy refreshing L3VPN service status. As a result, the client fails to respond quickly. Two solutions are available:
