iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1
How to Use This Lab Preparation Workbook In 2014 Cisco announced a new CCIE Routing & Switching blueprint for their V5 of the Lab Exam. This change was one of the biggest changes we've seen the over 14 years since we've been delivering cutting-edge CCIE training materials. The changes consisted of a modification of the lab structure to now include:
A restructure of the way the lab is delivered. You will first have to complete a Troubleshooting section where you'll have access to the rack that Cisco provides you to do so. The next section consists of the Diagnostics section, which is done without access to your rack. The third section is the Configuration section, which is the actual "lab" that most people focus on, and have been primarily concerned about in the past. With this new lab structure, it's VERY IMPORTANT that you are well-prepared for all three Sections of the Lab Exam. At any point, you could fail the Lab Exam if you don't receive enough points in 1 of the 3 sections.
Cisco has also made a drastic change in the topology that you'll be given. It's common knowledge at the time of this book's publication that the topology you're given has gone from their previous 6 to 8 router / 4 switch topology (seen in the labs previous to V4), to a topology that could potentially consist of up to 40 routers and 8 switches. It's imperative that you work through practice scenarios on a large topology, so you're familiar with the intricacies and technological specifics that can be introduced with a topology that large.
Cisco has also changed their retake policy which now requires their CCIE candidates to wait longer durations before their next attempt(s). Below we have listed Cisco's new policy.
And, finally, Cisco has created this impressive blueprint and broken it into sections. Cisco provides you with the 5 section titles and the number of points so you're able to understand how their grading works and how much focus and attention is placed on that various section. The primary section outline is provided below; however, we have not provided all of the topics and subtopics that Cisco has provided. We recommend that you reference Cisco's website URL, which provides these details for the Routing & Switching V5 Lab, which will require you to have a CCO and Cisco Learning Network login prior to being given access. That URL was found here at the date of this book's publication.

iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1 About the CCIE Lab Exam The CCIE Lab Exam is an eight-hour, hands-on exam which requires you to configure and troubleshoot a series of complex networks to given specifications. Knowledge of troubleshooting is an important skill and candidates are expected to diagnose and solve issues as part of the CCIE Lab Exam. You will not configure end-user systems, but are responsible for all devices residing in the network (hubs, etc.). Point values and testing criteria are provided. More detail is found on the Routing & Switching Lab Exam Blueprint and the list of Lab Equipment and IOS Versions. Cost The Lab Exam cost does not include travel and lodging expenses. Costs may vary due to exchange rates and local taxes (VAT, GST). You are responsible for any fees your financial institution charges to complete the payment transaction. Price not confirmed and is subject to change until full payment is made. For more information on the Lab Exam Registration please reference the Take Your Lab Exam tab. Lab Environment The Cisco documentation is available in the lab room, but the exam assumes knowledge of the more common protocols and technologies. The documentation can be navigated using the index. No outside reference materials are permitted in the lab room. You must report any suspected equipment issues to the proctor during the exam; adjustments cannot be made once the exam is over. Lab Exam Grading The labs are graded by proctors who ensure that all the criteria have been met. They will use automatic tools to gather data from the routers in order to perform preliminary evaluations. Candidates must reach a minimum threshold in all three sections and achieve an overall passing score. Lab Format The CCIE Routing & Switching Lab Exam consist of a 2 hour Troubleshooting section, a 30 minute Diagnostic section, and a 5 hour Configuration section. Candidates may choose to borrow up to 30 minutes from the Configuration section and use it in the Troubleshooting section.

iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1 Results You can review your Lab Exam results online (login required), usually within 48 hours. Results are Pass/Fail and failing score reports indicate major topic areas where additional study and preparation may be useful. Reevaluation of Lab Results A Reread involves having a second proctor load your configurations into a rack to re-create the test and re-score the entire exam. Rereads are available for the Routing & Switching, and Service Provider technology tracks. A Review involves having a second proctor verify your answers and any applicable systemgenerated debug data saved from your exam. Reviews are available for all other tracks. Payment Terms Make your request within 14 days following your exam date by using the "Request for Reread" link next to your lab record. A Reread costs $1000.00 USD and a Review costs $400.00 USD. Payment is made online via credit card and your Reread or Review will be initiated upon successful payment. You may not cancel the appeal request once the process has been initiated. Refunds are given only when results change from fail to pass. Troubleshooting The CCIE Routing & Switching Lab Exam features a 2 hour troubleshooting section. Candidates will be presented with a series of trouble tickets for preconfigured networks and need to diagnose and resolve the network fault or faults. As with the configuration section, the network must be up and running for a candidate to receive credit. Candidates who finish the Troubleshooting section early may proceed on to the Diagnostic section, but they will not be allowed to go back to Troubleshooting. NOTE This concludes any referenced content seen or found on Cisco's Learning Network.

2. Configure Cat4 as the server of the VTP domain iPexpert. 3. Configure Cat3 not to update its VLAN database. Cat3 should silently forward VTP packets. 4. Configure Cat1 and Cat2 as client of Cat4. 5. Add VLAN 150 and 151 on Cat4, and check that those VLANs are now present on Cat1 and Cat2, but not on Cat3. 6. Add VLAN 1500 on Cat4, and make sure that it is propagated to Cat1 and Cat2, but not to Cat3. 7. Configure the VTP domain with a password of "090909". This password should be stored in the NVRAM database. 8. Ensure that the next VLAN created will not be propagated to switches where this VLAN is not allowed on any trunks. 9. Ensure that Cat2 can take over the server role in the case of a failure of Cat4. 10. Configure R2 in VLAN 150 and R5 in VLAN 1500 as client ports. Since Cat1 does not have any client ports in VLAN 151, make sure that broadcast packets in VLAN 151 will never be transmitted to Cat1.

Version 5.1A
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1 4. Ensure that Cat4 controls LACP negotiation. 5. Ensure that E5/0 will be used as LACP failover if 9 members are present in the Port-channel. Create a static redundant routed port, Po14, between, Cat1 and Cat2. Use the subnet 10.14.0.x/24 where x is the device. 6. On the Port-channel between the Cat2 and the Cat4, all the TCP flows from a source MAC address to the same destination MAC address should use the same member in all the portchannels just configured. 7. On the Port-channel between the Cat3 and the Cat4, make sure that all the flows coming from a MAC address are using the same PagP member when the packet returns to this MAC address. 8. Configure the four switches with a mechanism to disable the port-channel in the case of a misconfiguration that leads to the port-channel receiving Spanning-Tree BPDUs on two different members.

Configure Cat2 as the primary root bridge for VLAN 21. Configure Cat4 as the secondary root bridge for VLAN 21. Do not use a command containing priority in order to achieve this. Optimize the timers to the number of switches. 5. Configure Cat3 as the primary root bridge on for VLAN 22. Configure Cat1 as the secondary root bridge for VLAN 22. Do not use a command containing root in order to achieve this. 6. In VLAN 22, make sure that Cat2 and Cat4 will be the least preferable switches to become the root of this network. 7. On VLAN 22, change the hello timer to 5s, the max aging time to 20s and the forward delay to 15s. 8. With all connections up on VLAN 21, the traffic from R6 to R9 should be forwarded using the following path: Cat2-Cat1-Cat3-Cat4. 9. With all connections up on VLAN 22, the traffic from R6 to R9 should be forwarded using the following path: Cat2-Cat3-Cat4. 10. With all connections up on VLAN 21, the traffic from Cat1 to Cat2 and from Cat3 and Cat4 should flow over the E3/0 connections. 11. With all connections up on VLAN 22, the traffic from Cat1 to Cat2 and from Cat3 and Cat4 should flow over the E3/0 connections. 12. Reduce the convergence time associated with indirect failures in the network. Enable Rootguard on the e3/1 interface of Cat1. 13. Enable the Uplinkfast feature on the switches where it cannot create loops. When a failure occurs on a switch with Uplinkfast feature on, a maximum of 100 dummy multicast packets have to generate every second in order to update the rest of the network bridging tables. 14. Configure R6 as a client in VLAN 21 in access mode. 15. Configure R9 as a client with a trunk connection allowing VLAN 22. VLAN 22 should be native of the dot1q trunk. 16. Configure the ports connected to the routers to transition immediately from blocked to forwarding. 17. If R6 sends BPDUs, configure the switch port to transition to error-disabled when it happens. Configure the port to re-enable itself automatically after 1 minute. 18. If R9 sends BPDUs, configure the switch port to ignore and silently drop them. 36 | P a g e

Multicast support has to be configured. 2. On R1, configure a static route to the loopback0 of R3. Check that you can ping the loopback0 of R3 with a ping sourcing on the tunnel interface of R1. 3. On R2 tunnel interface, disable proxy-arp. 4. On R1, configure a static route to the loopback0 of R2 using the tunnel interface on R2 as the egress interface. 5. On R1, ensure that you can ping the loopback0 of R2 with a ping sourcing on the tunnel interface of R1. Create a static ARP entry to achieve this task. 6. On R6, configure a static route to network 10.1.0.0/16 pointing to E0/0. Check that you can ping the loopback0 of R2 and R3. 7. Disable proxy-ARP on E0/1 of R2 and R3. Ensure that you can ping the loopback0 of R2 and R3 with a ping sourcing from the E0/0 ip address of R6. 8. Configure a GRE tunnel interface Tunnel0 between the loopback0 of R6 and the loopback0 of R3. Use ip address 36.0.0.3/24 on R3 and 36.0.0.6/24 on R6. Configure default routes on R6 and R3 to each other with an AD of 250. 9. On R6, configure a static route to the loopback network of router R3 using the Tunnel 0 as egress with an AD of 5. The tunnel0 interface should go down because of a recursion issue. Leave this tunnel0 down as it is. 10. Configure static routing so that you can ping the loopback0 of R1 with a ping sourcing from the loopback0 IP address of R6. The ping should follow the R6-R3-R1 route and use the DMVPN tunnel. 11. Configure a GRE tunnel interface Tunnel16 between the loopback0 of R6 and the loopback0 of R1. Use ip address 16.0.0.1/24 on R1 and 16.0.0.6/24 on R6. 12. On R3, configure a floating default route that will be used in the case that the tunnel interface to R1 goes down. This floating route should not point to R1, but to R5 as a next-hop. At this point, you are not asked to configure all the static routing that will make the backup path operational. 13. On R4, configure a default-route using the next-hop of R1. On R1, configure a static route to the network 10.1.4.0/24 pointing to the next-hop on R4. 14. On R4, configure a default-route using the next-hop of R5 with an AD of 5. 56 | P a g e
Version 5.2C
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1
15. The default-route using the next-hop of R5 should be used when the loopback0 of R1 has become unreachable. Use object tracking and IP SLA. 16. On R5, configure default routing using policy-based routing. This default routing should be pointing to a next-hop of R3 IP address using PBR. When CDP detects that R5 to R3 connectivity is down, the traffic should be routed over R4. Do not use local policy-base routing. 17. On R9, use local-policy based routing to route to the loopback interface of R6. 18. On R6, use local-policy based routing to route to the loopback interface of R9. You should be able to ping the loopback0 of R6 with a ping sourcing from the loopback0 of R9.

Configuration Tasks 1. R1, R2, and R3 are in a hub and spoke topology where R1 is the hub and R2 and R3 are the spokes. DMVPN is the underlying used technology. Configure OSPF process 1 area 0 in this network. The election of a DR should not take place. On routers R2 and R3, you are not allowed to change the default network type and not allowed to modify the timers. 2. R4, R5, and R1 are also in a hub and spoke topology where R4 is the hub and R1 and R5 are the spokes. DMVPN is the underlying used technology. Configure OSPF process 1 area 0 in this network. The election of a DR should take place in this network. The DR should always be on the hub router. Multicast is not enabled on the DMVPN tunnels. 3. On R1, R2, R3, R4, and R5, configure loopbacks 0 as the OSPF router-ids and advertise loopback0 of the routers into OSPF in the following areas:
Table 14.2 R1
Area 1
R2
Area 2
R3
Area 3
R4
Area 4
R5
Area 5
Check that you have full reachability between the loopbacks, especially on R2, check that you can ping the loopback of R5 sourcing from the loopback of R2. 4. Configure the network 10.1.236.0/24 into area 236 on R2, R3, and R6. 5. R2 should always be elected as the DR, and R3 should always be elected as the BDR. 6. Advertise only the loopback 0 of R6 into OSPF area 236. Do not use a network statement. On R5, check that you can ping the loopback of R6 sourcing from the loopback of R5. 7. We are going to have links faster than 100M in the network. In the whole OSPF network, a gigaethernet link should have a cost of 1 and a fast ethernet link should have a 10. 8. Manipulate the OSPF cost so that R1 prefers R2 over R3 to reach the loopback of R6. Do not configure anything under the interfaces. 9. Configure OSPF version 3 area 0 for IPv4 between R6 and R9. Use the following global unicast addresses: 86 | P a g e

NOTE Load the initial configuration files before starting to work on the tasks.
Configuration Tasks 1. R1, R2, and R3 are in a hub and spoke topology where R1 is the hub and R2 and R3 are the spokes. DMVPN is the underlying used technology. Configure OSPF process 1 area 0 in this network. The election of a DR should take place in this network. The DR should always be on the hub router. 2. The loopback0 networks of R1, R2, and R3 should present in the OSPF database of R1 as LSAs type 1. 3. Configure the network 10.1.236.0/24 into area 236 on R2, R3, and R6. Redistribute only the loopback0 of R6 into the area 236. 4. Configure the network 10.1.69.0/24 into area 69 on R6 and R9. Add the loopback0 of R9 into the area 69 process as a network statement. 5. Configure area 236 as a stub area. 6. Ensure that there is IP connectivity between loopback0 of R9 and the loopback0 of R1. Do not use a virtual-link, as the transit area is a stub area. The path through R3 should be used. Use an IP address of 36.0.0.3/24 and 36.0.0.6/24 when necessary. 7. Configure the network 10.1.14.0/24 into area 14 on R1 and R4. Add the loopback0 of R4 into the area 14 process as a network statement. 8. Configure the network 10.1.47.0/24 into area 47 on R4 and R7. Add the loopback0 of R7 into the area 47 process as a network statement. 9. Ensure that there is IP connectivity between loopback0 of R7 and the loopback0 of R2. 10. Configure the network 10.1.35.0/24 to be part of area 0. 11. Configure the network 10.1.45.0/24 and the network 10.1.5.5/32 to be part of area 45. 12. Configure an OSPF cost of 60000 on the interfaces belonging to the network 10.1.14.0/24. 13. On R7, when performing a trace route from the loopback of R7 to the loopback of R3, we can observe that the trace route is following the path R7, R4, R5, and R3. The routing is using a nonbackbone area, that is to say area 45, as a transit. Without modifying any OSPF costs, ensure that the trace route is using the R7, R4, R1, and R3 path. 93|P a g e
Version 5.1A
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1 14. OSPF should not exchange periodic hellos and periodic refreshes of LSAs over the point-to-point connection between R6 and R9. Configuration can only be applied on R9. 15. Configure plain-text authentication on the connection between R6 and R9. The key value should be set to “iPexpert”. Make sure that this authentication is enforced even if this is an on-demand circuit. 16. Configure MD5 authentication only on the connection between R5 and R3. The key value should be set to 2 and the password to “iPexpert2015”. On R5, configure authentication under the routing process. 17. Protect the connection between R5 and R4 with the Null authentication. 18. OSPF process is reflooding by default every LSAs every 30 minutes. This should not be necessary for LSAs sent out of the two serial interfaces on R5. 19. Configure the following loopbacks on R9:
Table 15.2 Loopback 8
10.8.9.9/16
Loopback 9
10.9.9.9/16
Loopback 10
10.10.9.9/16
20. Those 3 loopbacks should be seen in the area 0 routing table as a single summary network. Use internal summary. 21. On R6, ensure that the summary route created in Task 20 is not present in the routing table pointing to Null0. 22. On R9, redistribute the pre-configured routes into OSPF and make sure that they appear as one routing entry in the routing table in all other OSPF routers. 23. Configure area 45 in a way that LSAs never age out in this area.

Configuration Tasks 1. R1, R2, and R3 are in a hub and spoke topology where R1 is the hub and R2 and R3 are the spokes. DMVPN is the underlying used technology. Get OSPF routing up and routing with process 1 area 0 in this DMVPN network. The election of a DR should not take place in this network. Do not modify any OSPF timers. 2. Add the loopback0 of R1, R2, and R3 into the area 0 process as network statements. 3. On R2, R3, and R6, configure the network 10.1.236.0/24 as part of OSPF area 236. Add the loopback0 of R6 into the area 236 process as a network statement. 4. In the R6 routing-table, the only IA OSPF-learned route should be a default route with the ABRs as the next-hop. 5. On R6, configure static routing to ensure the reachability of the loopback0, loopback1, and loopback2 networks of R9. R9 should be configured with a default route. 6. On R6, redistribute the static routes configured in Task 5 (except loopback2) into OSPF. In the routing-table of R1, 10.1.9.0/24 should show as E1 and 10.11.9.0/24 should show as E2. On R1, ensure that you can ping the loopback0 and loopback1 of R9 from the loopback0 of R1 as a source. 7. Area 236 is a totally Not-so-stub area having two ABRs to area 0. By manipulating OSPF cost, ensure that the default route in the R6 routing table is using R3 as a next hop. The cost of the default route to R2 should be modified and this cost should be the default cost +1. 8. On R1 and R4, configure the network 10.1.14.0/24 as part of OSPF area 14. Add loopback0 of R4 into the area 14 process as a network statement. 9. Configure Area 14 in a way that it does not receive any LSA 5 updates. Ensure full reachability and test that you can ping from R4 the loopback 0 of R9 from the loopback 0 of R4 as a source. 10. Area 35 is a totally NSSA area. On R3 and R5, configure the network 10.1.35.0/24 as part of OSPF area 35. Inject the loopback0 of R5 into the area 35 process as a network statement. 11. Redistribute loopback1, loopback2, loopback3, and loopback4 of R5 into the area 35 each as a N2 route and each with a metric of 55. Make sure that on R5, you can ping to the loopback0 of R9 with the ping sourcing from loopback 4 of R5. 12. Block the LSA 7 to LSA 5 translation for the network 10.11.5.0/24 using a summary-address command. 13. Filter the forwarding address for the type-7 LSAs originated at R5 using the area 35 range not-advertise in command on the ABR. 100 | P a g e
Version 5.2C
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1 14. Instruct R3 to become the forwarding address itself and check that the IP address reachability is restored, that is to say check that you can ping to the loopback0 of R9 with the ping using as a source the loopback4 of R5. 15. On R1, there is a default route pre-configured. This default route should be redistributed into OSPF only if the network 10.21.5.0/24 is present in the routing table of R1. Use IP SLA to track, in a reliable way, this network. You are allowed to add one static route in this task.

Configuration Tasks 1. R1, R2, and R3 are in a hub and spoke topology where R1 is the hub and R2 and R3 are the spokes. DMVPN is the underlying used technology. Configure OSPF process 1 area 0 in this network. Use point-to-multipoint network type on the hub and the 2 spokes. 2. Configure the network 10.1.36.0/24 into area 0 on R3 and R6. 3. The loopback 0 networks of R1, R2, R3, and R6 should present in the OSPF database of R1 as LSAs type 1. 4. On R1, prevent the flooding of link-state advertisements to R2 by using the database-filter all out command applied to a neighbor. Make sure that R2 is still having full reachability. 5. Configure network 10.1.69.0/24 into area 69 on R6 and R9. Use network statement to advertise loopback0. Distribute loopback1, loopback2, loopback3, and loopback4 of R9 into the area 69 process as E2 type. 6. Configure the following router-ids and make sure that they are in use by the process.
Table 17.2 R1
1.1.1.1
R2
2.2.2.2
R3
3.3.3.3
R6
6.6.6.6
R9
9.9.9.9
7. Ensure that the loopback0 network of R1 is not included by the OSPF process in the routing table of R9. Use prefix-list and distribute-list. 8. On R9, the network 10.21.9.9/32 should be filtered out and not be propagated. Use distribute-list and access-list. 9. On R3, configure a default route pointing to R5. On R5, configure a default route pointing to R3. Confirm that you can ping from R3 the loopback0 of R5 10.1.5.5 from the loopback 0 of R3. 10. Redistribute this default route into OSPF area 0. 11. On the ABR R6, configure the area 0 to advertise a summary network of 10.1.0.0/16 within the area 69.
105|P a g e
Version 5.1A
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1 12. Try to ping loopback0 of R5 from loopback0 of R9. Because of the presence of a 10.1.0.0/16 route on the ABR, the default route is not being used and the ping is failing. Ensure that this 10.1.0.0/16 is suppressed. 13. On R1, the network 10.41.9.9/32 should be present in the OSPF database but not in the routing table. Manipulate the administrative distance to achieve this. 14. Configure R6 so that R1 doesn’t receive the 10.1.9.9/32 prefix. Use prefix-list and area filter-list. 15. Configure a NSSA area 14 between R1 and R4. On R4, redistribute all connected interfaces into OSPF. 16. On R1, filter the 10.11.4.4/32 and 10.22.4.4/32 out and let the other networks coming from area 14 advertise to the area 0. Use summary-address command. 17. Configure on all the routers a feature that will remove the transit networks from the OSPF database. Check that IP reachability is still working between the OSPF advertised prefixes once this feature is enabled. 18. On R9, configure the minimum interval for accepting the same LSA to 80 ms. 19. On R9, set the following rate-limit values for LSA advertisement:
Table 17.3 Start-interval
10 ms
Hold-interval
100 ms
Max-interval
5000 ms
20. On R9, configure OSPF throttling timers:
Table 17.4 Spf-start
10 ms
Spf-hold
4800 ms
Spf-max-wait
90000 ms
21. On R9, configure OSPF Update flood packet-pacing to 5 ms. 22. On R9, in order to improve convergence, enable incremental SPF.
106 | P a g e
Version 5.2C
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1 23. R9 should fire up a syslog message when more than 3 prefixes are redistributed. First warning should be sent when 80% of the threshold is reached. 24. On R9, limit to 1000 the number of non-self-generated LSAs the OSPF routing process can keep in the OSPF database.

Version 5.2C
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1 4. Configure an eBGP peering between R8 in AS 8 and R7 in AS65001. 5. The loopback0 of R4 should be present in the BGP database with an origin attribute of incomplete. The loopback0 of R7 should be present in the BGP database with an origin attribute of internal. 6. On R8, manipulate the weight attribute so that the route to 10.1.4.4/32 is pointing towards R6. Use a prefix-list called WEIGHT_PL and a route-map called WEIGHT_RM. 7. The loopback0 of R6 should be present in the BGP database with an origin attribute of incomplete. 8. In order to reach the 10.1.6.6/32 loopback, routers in AS 65001 should route the traffic over R8 through AS 8. Change the configuration on R7 and use a route-map called LOCALPRF_RM. You don’t have to test connectivity in this task. 9. The loopback0 of R8 should be present in the BGP database with an origin attribute of IGP. 10. Configure R8 so that the traffic originated on R6 is going through AS 65001 to reach the network 10.1.8.8/32. On R6, 10.1.8.8 route via R8 should have the following AS-path attribute: 8 8 8 8 i. Use a prefix-list called PREPEND_PL and a route-map called PREPEND_RM. 11. Configure OSPF area 0 between R6 and R2. 12. Configure iBGP connection between R6 and R2 – use AS 65002. 13. The loopback0 of R2 should be present in the BGP database with an origin attribute of incomplete. 14. Configure an eBGP connection between R6 and R3 in AS 3. Redistribute the EBGP next-hop into OSPF area 0. 15. Configure an eBGP connection between R2 and R3 in AS 3. Redistribute the EBGP next-hop into OSPF area 0. 16. Advertise loopback0 and loopback1 of R3 using network statements. 17. Ensure that the traffic is routed via R2 to reach network 10.1.3.3/32. Configure R3 and use the prefix-list called MED_PL 2 and a route-map called MED_RM2. Use a MED value of 200. 18. Ensure that the traffic is routed via R6 to reach network 10.11.3.3. Configure R3 and use the prefix-list called MED_PL 6 and a route-map called MED_RM6. Use a MED value of 300. 19. On R2 and R6, advertise the network 10.1.26.0/24 with a network statement. 20. On R3, modify the origin of route 10.1.26.0/24 and ensure that this route is reached primarily through R6. Use a prefix-list called ORIGIN_PL and a route-map called ORIGIN_RM. 121|P a g e
Version 5.1A
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1
21. On R6, advertise the network 10.22.6.0/24 using a network statement. 22. This network should be advertised to router R4 using the MED 500 and prepending one more AS in the AS-path. Use a prefix-list called ALWAYSCOMPMED_PL and a route-map called ALWAYSCOMPMED_RM. 23. Configure R4 and ensure that R4 always prefers the route with the lowest MED, that is to say the route to R6 is pointing to R7 on R4. 24. Configure an eBGP connection between R2 and R5 (AS 5) and between R4 and R5. Advertise the loopback of R5 into BGP with an origin of “?”. 25. On R4, prepend the AS 65001 4 times when advertising the network 10.1.7.7/32 to R5. The route from R5 to the loopback0 should now be transiting through AS 65002. 26. On R5, the AS-path attribute should be ignored and the route to the 10.1.7.7/32 network has to point towards R4 and not transit through AS 65002 anymore. Use MED to achieve this. 27. On the peering between R2 and R5, shut down the peering if more than 50 BGP updates are advertised from R5 to R2. A syslog message should be sent when more than 40 BGP updates are advertised from R5 to R2.

Advertise the loopbacks of R4, R5, R7, R8, R6, and R9 in the OSPF process. Use network statements. Make sure that you can ping from the loopback0 of R7 to the loopback0 of R9. 4. Advertise the networks 10.1.77.0/24 and 10.1.99.0/24 in the OSPF process. Use network statements. Make sure that no OSPF neighborships will ever be formed on those networks. 5. Configure PIM sparse mode on the networks 10.1.69.0/24, 10.1.236.0/24, 11.1.1.0/24, and 10.1.148.0/24. 6. Configure IP PIM dense mode on network 10.1.47.0/24. No PIM adjacency should be formed over this connection. Use the command ip pim neighbor-filter on R4. 7. The source of the multicast stream 224.2.2.2 is located on the VLAN 77. The receiver of this multicast stream is on the VLAN 10.1.148.0/24. Enable multicast connectivity between this source and this receiver. You are not allowed to remove the filter configured in the previous question, and consequently not allowed to build a PIM adjacency over the connection between R4 and R7. On R1, R4, R7, and R8, configure statically the loopback0 of R1 as the RP for all multicast groups. 8. Configure the interface E0/1 on R7 to join the group 224.2.2.2 and check that you can ping this multicast group from R8. 9. Make sure that interface E0/1 on R5 can receive traffic multicast for the group 224.3.3.3 only if it is sourced from the loopback0 of R1. Do not enable PIM on this interface. 10. Verify that you can ping this multicast group 224.3.3.3 from R1 only when the ping is sourced from the loopback0 of R1. 11. R9 has to be protected from an IGMP DOS attack. On the interface E0/0 of R9, allow the maximum number of IGMP states to be 25. 12. R6 should only accept on the interface E0/1 multicast clients that want to join a group in the range 225.0.0.0/8. 13. Configure interface E0/1 of R9 to join multicast groups 225.2.2.2 and 226.2.2.2. Check on R6 that the filtering configured in the previous question is working. 14. On the network 10.1.99.0, there is only one client receiving several multicast streams. As soon as this client is sending an IGMP leave group message, the router should immediately stop forwarding this multicast stream on the LAN and not try to send a group-specific query for this multicast group.

The backup querier should become the querier for this LAN if it hasn’t seen a query packet within 1 minute. 16. On R9, IGMP protocol should communicate to the multicast clients that they should report their group’s membership in a maximum of 30 seconds after receiving a query. 17. There is a server that is connected to the network 10.1.136.0/24. This server is sending broadcast UDP traffic to port 2500 to a client connected to the network 10.1.148.0/24. This broadcast traffic should be transported by the multicast group 227.7.7.7 when crossing the connection between R2 and R1, and the connection between R3 and R1. 18. The multicast traffic should be converted back to a broadcast when reaching the network 10.1.148.0/24. 19. Configure bidirectional PIM for a multicast stream of 224.22.22.22 on the network 11.1.1.0/24 and 10.1.148.0/24. The loopback0 of the R1 has to be configured as the RP and the mapping agent in this PIM bidirectional setup. 20. Configure R6 to limit to total bandwidth for multicast traffic to 20 M on all its interfaces in the egress direction. 21. Configure R1 to limit to 5M the bandwidth that the multicast stream with a destination of 224.22.22.22 can use out of the tunnel interface.

You are not allowed to clear the DF-bit or to intervene in the TCP negotiation. 7. Encrypt the GRE traffic tunnel between R2 and R9. Use a GRE over IPsec tunneling. Use a hash of MD5 and pre-shared key of “iPexpert” during the phase 1 negotiation. 8. Between R2 and R9, use esp-3des encryption and an esp-md5-hmac authentication during the phase 2 negotiation. Make sure that the IP connectivity between the loopback0 of R2 and the loopback0 of R9 is still up and running. 9. Configure IPsec encryption on the ethernet connection between R5 and R8. Use an encryption of AES, a DH group number 2 and pre-shared key of “iPexpert” during the phase 1 negotiation. 10. Between R5 and R8, use esp-3des encryption and an esp-sha-hmac authentication during the phase 2 negotiation. 11. Create a VTI on both ends. IP address on R5 is 192.168.58.5/24 and IP address on R8 is 192.168.58.8/24. 12. Traffic going from loopback0 of R5 to loopback0 from R8 should be encrypted in both directions. You are not allowed to use a dynamic routing protocol or a default route.

Configuration Tasks 1. AAA
Configure R1 for AAA.
Users who telnet to this device should be authenticated by the default method list using a line password (“iPexpert”). Console line should not be affected.
PPP authentication requests should be authenticated using RADIUS server (10.10.11.90).
Protect RADIUS communication using key “iPexpert”. RADIUS traffic should be sent using new port numbers.
Network access should be authorized – if RADIUS is down authorization should succeed for authenticated users.
Enable accounting for network traffic – records should be kept for when a session initiates and when it terminates.
2. Local Authentication & Authorization
Enable SSH on R3. Use domain-name “ipexpert.com”.
Create two local user accounts – “admin” and “secops”.
When “admin” connects to R3 remotely via SSH it should be automatically placed at level 15 after successful authentication.
When someone authenticates as “secops” he/she should be placed at level 8.
Anyone who knows enable password (“cisco”) should be able to access Privilege Level.
Make sure that enable password is MD5-encrypted.
Don’t use AAA to accomplish this task.
3. AAA EXEC Authorization
210 | P a g e
Remove local authentication on R3. Enable AAA.
Users “admin” and “secops” should be still assigned to privilege levels 15 and 8, respectively, after successful authentication. Version 5.2C
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1
User “secops” should be able to access the following commands: o
show running-config
o
configure terminal
o
ip routing
o
ip route
User “admin” should have access to all commands.
When “secops” issues the enable command he should be automatically given Privilege Level access without prompting for password.
Don’t use any default method lists in this task.
4. AAA with CLI Views
Configure R2 for CLI Views using AAA.
Create a local user account “administrator” who should be given access to all commands.
Create a local user account “netops” who should be able to do the following:
211|P a g e
o
Access all show commands except for any show crypto command.
o
Issue “ping” and “telnet”.
o
Configure any dynamic routing protocol.
Create a local user account “secops” who should be able to do the following: o
Access all show crypto commands.
o
Configure any crypto command in the global config mode.
Create another user account - “ops”. This person should be always able to do what “netops” and “secops” can do.
Use “iPexpert” as a password for all views.
Version 5.1A
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1 5. Traffic Filtering – Standard ACLs
R8 is configured with the following loopback networks: o
111.111.111.2/32
o
111.111.111.4/32
o
111.111.111.6/32
R1 should be configured to drop & log packets sourced from those addresses using a Standard ACL. This ACL should have as few entries as possible with a minimum overlap.
All routers should be able to reach R3 only from interfaces configured with odd IPv4 addresses.
Traffic sourced from other IPv4 addresses should be dropped.
Implement this using a Standard ACL with a single “deny” entry.
You are allowed to change a single IP address on R8.
6. Traffic Filtering – Extended ACLs
Configure an IPv4 ACL on R9’s E0/0 inbound. Allow the following traffic:
o
OSPFv2 – be very specific here.
o
R1 acts as a Telnet, Web and SQLNET (TCP 1521) server – permit this traffic only to its loopback0 in a single ACL line.
o
UDP-based traceroute (IOS) to any destination – use a single ACL line.
o
All TCP segments destined to R1’s Loopback 44 but only with SYN and ACK bits set and FIN bit being not set.
o
All IP packets with any source and destination with a TTL 0-253 and 255 (in a single ACL line).
o
Routers R2, R9, and R8 should be able to ping all interfaces of R1 (regardless of the TTL in the packets). R1 should be able to ping all routers except R3 as well.
Configure an IPv6 ACL on R9’s E0/0 inbound in the following way: o
212 | P a g e
Allow Telnet to R1’s Loopback 0. Version 5.2C
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1
o
Deny all IPv6 packets with missing or unknown L4 information.
o
Deny all IPv6 packets with Routing Extension Header.
o
Make sure OSPFv3 adjacencies are not affected, same as all ICMPv6 packets.
Deny and log all other IPv4 & IPv6 traffic. Make sure you see a log message for every packet dropped by this entry.
7. Traffic Filtering – Time Ranges & Object-Groups
All web traffic destined to R8’s Loopback 12,14, and 16 interfaces should be denied during business hours Mon-Fri 9am-5pm. This Includes encrypted traffic.
November 11, 2014 has been declared a no-work day. Ensure that no traffic is allowed to the above mentioned loopbacks for the entire day.
Permit and log all IPv4 DNS traffic (TCP and UDP) to R8’s Loopback0 and 12. Include source MAC address in the logs. Use a single ACL entry to configure this.
All other traffic should not be affected.
8. Traffic Filtering – IP Fragments
Modify an ACL from the previous task to block all IPv4 fragments regardless of the time/date.
Block all IPv4 and IPv6 fragments coming to E0/1 on R2 – don’t use an access-list to accomplish that.
9. Traffic Filtering – Reflexive Access-Lists
213|P a g e
Users in VLAN 70 should be allowed through R2 to any destination when using WWW, Telnet, and SSH.
Return traffic should be allowed dynamically. Dynamic entries should timeout after a minute.
Only allow OSPF, ICMP, and Telnet inbound on E0/1.
Use Reflexive Access-Lists.
Version 5.1A
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1
10. Dynamic (Lock & Key) Access-Lists
You decided that traffic originating in VLAN 70 should be allowed through R2 only for authenticated users.
Users will be authenticating using Telnet to 2.2.2.2 over port 3023.
Sessions should not be idle for more than 2 minutes.
Sessions longer than 30 minutes require re-authentication.
A valid local user account for this task is “intuser” with password “cisco”.
AAA should be already enabled on this device (from one of the previous tasks).
11. Policy-Based Routing
Telnet traffic sourced from R2’s loopback0 destined to 3.3.3.3 should be blackholed on R8.
Use PBR to accomplish that.
12. Unicast Reverse Path Forwarding (URPF)
Enable Loose Mode uRPF on R8.
Packets received with unknown sources should be dropped.
Don’t use a default route when uRPF decisions are made.
An exception to this policy is packets coming from 192.168.1.0/24 – they should be allowed and logged.

Version 5.1A
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1
Configuration Tasks 1. NBAR
Using NBAR create and apply a policy outbound on R2’s E0/1 to drop the Slammer worm traffic.
The Slammer worm propagates over UDP port 1434 and its packets are exactly 404B long.
In the same policy all HTTP packets with string “attack” in the URL should be dropped but only when traffic is going to a WWW server 8.8.8.8 (R8).
The string should be case insensitive.
2. NBAR Next-Gen (NBAR2)
Configure R8 to drop all terminal-related traffic except PCANYWHERE.
Also implement a policy for peer-to-peer traffic: o
All clear-text packets should be rate-limited to 200kbps.
o
All encrypted traffic should be dropped.
Enable classification of IPv6 traffic that is carried over Teredo tunnels.
Use a technology that examines IPv4 and IPv6 packets.
Apply the policy outbound on E0/1.
3. NBAR Protocol Discovery
Enable NBAR Protocol Discovery on R9’s E0/0.
Make sure statistics are obtained for IPv4 and IPv6 traffic.
4. TCP Intercept
220 | P a g e
There are multiple servers in VLAN 70 hosting various TCP-based applications.
Several DoS attacks took place recently targeted at those devices. Version 5.2C
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1
Configure R2 to intercept TCP connection requests to this segment.
If the total number of half-open connections reaches 400, R2 should start randomly dropping them.
This should cease if the number of half-open sessions falls below 200.
Make sure router stops managing the sessions after 40 minutes of inactivity.
5. TCP Intercept Passive Mode
There are some other TCP servers that were recently attacked with large amount of spoofed SYN requests (3.3.3.0/24 segment).
R3 should be configured to send a reset to the server under attack but it should not participate in the handshake.
The reset segment should be sent if a session does not establish within 20 seconds.
If a number of connection attempts within the last minute exceed 100, or when a total number of half-open sessions exceed 300, the sessions should be reset faster - after 10 seconds.
If a FIN exchange or RST packet was seen for a session, it should be dropped after 7 seconds.
6. Packet Logging
221|P a g e
Configure R1 to send all logged messages to a Syslog server located at 10.70.70.100.
Use facility type local1.
Use detailed time stamps for log and debugs including local time zone, and the time of day.
Logs should be also sent to a buffer – allocate 16384B of memory for this purpose.
Log messages should be sent with source of 1.1.1.1 and they should be rate-limited to 200 per second except for Sev 1 messages.
Version 5.1A
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1 7. Port Security
Enable Port Security on Cat2.
Make sure that port connected to R1 will accept frames with R1’s MAC, but don’t configure address statically.
On the same interface also allow frames coming from 0000.2222.3333.
If a violation occurs frames should be dropped, and a Syslog and SNMP traps should be generated. The switch should try to automatically recover from a violation every 50 seconds.
Anytime the switch reboots it should not affect the Port Security table.

234 | P a g e
Version 5.2C
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1 TCP range 1433 1434 and a class called OFFICE_BOSS should be created for traffic originated from the LAN 10.1.222.0/24. 2. On R6, configure a policy-map called TRAFFIC_COLOURING. This policy-map should mark the VOICE traffic with the DSCP EF, the SQL traffic with the DSCP AF31, and the OFFICE_BOSS with the DSCP AF21. The remaining unclassified traffic should have the DSCP field reset to 0. 3. On the WAN link between R3 and R6, a QOS policy will be enforced. The Voice traffic should be prioritized before any other traffic in case of congestion. 10% of the bandwidth is allocated to VOICE traffic. 4. In case of congestion, the SQL traffic should have 30% of the bandwidth reserved and the OFFICE_BOSS traffic should have 20% of the bandwidth reserved. 5. In order to slow-down TCP traffic in case of congestion, some packets in the default queue should be randomly dropped before the queue is getting full and tail-dropping. 6. On the interface S3/0 of R6, enable WRED to begin to randomly drop packets with the IP precedence of 3 when the queue contains 20 packets and to tail-drop when the number of packets in the queue reaches more than 30 packets. 1 out of 5 packets should be randomly dropped. 7. On the interface S3/0 of R6, configure the minimum possible queue size. 8. On the interface S4/0 of R4, configure a hold queue of 200 packets. 9. On the interface S4/0 of R3, ensure that packets with a dscp of AF21 begin to be randomly dropped when the queue contains 100 packets and to tail-drop when the number of packets in the queue reach more than 200 packets. 1 out of 10 packets should be randomly dropped. 10. The TCP hosts that are transiting on the connection between R3 and R4 are supporting ECN. Enable WRED to take into account the DSCP field. Instead of randomly beginning to drop packets, WRED should be configured to mark the packet that was supposed to be dropped. The goal of this marking is to trigger the receiver to suggest the source to decrease the TCP window size.

Lab 38 Setup
This lab is intended to be used with online rack access. Connect to the terminal server for the online rack, and complete the configuration tasks as detailed below.
NOTE Load the initial configuration files before starting to work on the tasks.
Configuration Tasks 1. On the WAN link between R3 and R6, enforce a QOS policy using a policy-map called Serial_Policy1. This QOS policy has 3 classes of service. Under congestion, a class called BRONZE matching DSCP AF21 has 256 Kbits/s reserved, a class called SILVER matching DSCP AF31 has 256 kbits/s reserved, and a class called GOLD matching DSCP EF has 512 kbits/s reserved. 2. Class SILVER has to be shaped to 512 kbits/s with a normal burst size of 2048 bits. 3. Class BRONZE can obtain throughput up to a peak of 512 kbps if enough bandwidth is available. 4. On the interface E0/1.101 of R2, configure traffic-shaping. Limit the egress TCP traffic for destination port 80 to 1 kbps and the egress TCP traffic for destination port 443 to 300 kbps. Traffic not matching any access-list should be shaped to 100 kbps. 5. On R3 and R6, in the policy-map called Serial_policy1, add the following classes: the class called CUSTOMER1 is matching IP DSCP CS4 and the class called CUSTOMER2 is matching IP traffic with a destination TCP port of 69. 6. On R3 and R6, in the class called CUSTOMER1, police the traffic to a CIR of 128 kbps with a Bc of 1500 bytes and a PIR of 256 kbps with a Be of 4500 bytes. Packets that conform are sent, packets that exceed are re-marked with a COS of 0 and transmitted, and packets that violate are dropped. 7. On R3 and R6, in the class called CUSTOMER2, police the traffic to a CIR of 64 kbps with a Bc of 1500 bytes and a PIR of 128 kbps with a Be of 3000 bytes. Packets marked with a DSCP of AF32 and AF33 that conform are sent, packets with a DSCP of AF32 and AF33 that exceed are remarked with DSCP of AF11 and transmitted, and packets that violate are dropped. Packets that belong to neither AF32 nor AF33 are re-marked with a DSCP of AF12. Create a class-map called AF3233. 8. On the WAN link between R3 and R4, enforce a QOS policy using a policy-map called Serial_Policy_Parent. This QOS policy has only the class default. This policy-map is used to police the traffic to 100 kbps. 9. Create a policy-map called Serial_Policy_Child and enforce this QOS policy on the traffic that has already been policed in the previous question. The service-policy Serial_Policy_Child has two 240 | P a g e
Version 5.2C
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1 classes called CLASS1 and CLASS2. CLASS1 is matching UDP traffic and CLASS2 is matching TCP traffic. CLASS1 should be policed to 20 kbps and CLASS 2 should be policed to 50 kbps. 10. On the WAN link between R3 and R5, enforce a QOS policy using a policy-map called Serial_Policy_Percentage. This QOS policy has only the class default. This policy-map is used to police the traffic to a CIR of 60% of the available bandwidth and to a PIR of 90% of the available bandwidth. 11. On the WAN link between R3 and R5, configure PPP encapsulation and enable RTP enhanced header compression. 12. Consider that the connection between R3 and R4 is a satellite link. Enable RTP header compression on this connection. 13. On the link between R6 and R2, enforce a QOS policy using a policy-map called Serial_Policy_NBAR on R6. This QOS policy has 2 classes called LOTUS and URL. LOTUS class is matching Lotus notes traffic and is shaped to 512 kbps. URL class is matching HTTP traffic that contains a URL of /iPexpert is policed to 512 kbps.

The IP SLA control messages between R6 and R9 have to be authenticated using a key-chain called “iPexpert”. This key-chain should use key number 3 and a key string of “iPexpert”. 5. Between R6 and R8, configure on R6 a TCP operation to 10.1.68.8 on port 443 that doesn’t require R8 to be configured as a responder. 6. Between R8 and R2, configure on R8 a TCP operation to 10.1.108.2 on port 80 that requires R2 to be configured as a responder. 7. Configure R8 to perform every 30 seconds a DNS lookup on the DNS server 10.1.222.222 for the website www.ipexpert.com. 8. Configure GLBP between R8, R2, and R1 on the network 10.1.108.0/24. Virtual IP address is 10.1.108.133. 10% of the traffic should use R2 as a gateway and 10% of the traffic should use R1 as a gateway. 9. Authenticate the GLBP routers with a MD5 hashed password of “iPexpert133”. 10. Configure VRRP between R2 and R1 on the network 10.1.108.0/24. Virtual IP address is 10.1.108.144. When R2 is up and running, it should always be the master. 11. Authenticate the VRRP routers with a password of “iPexpert”. 12. Configure HSRP between R8 and R2 on the network 10.1.108.0/24. Virtual IP address is 10.1.108.155. As long as R8 is up and running, it should stay the master and when an outage occurs, it should recover this role 1 minute after coming back online. 13. When the ICMP echo from R8 to R6 fails, the priority should be decreased the minimum in such a way that R2 takes over the primary role. 14. Authenticate the HSRP routers with a clear text password of “iPexpert”.

Version 5.2C
iPexpert’s Lab Preparation Workbook for Cisco’s CCIE Routing & Switching Lab Exam, Volume 1 4. Ensure that the payload will not be modified by the static NAT entry configured on R9. 5. On R9, configure loopback0 with an IP address of 10.1.9.9/24. 10.1.9.0/24 is the inside network, 100.1.69.0/24 is the outside network. 6. On R9, configure a dynamic NAT that maps the internal range 10.1.9.0/24 to the public address range 100.1.69.241-100.1.69.255. When no more address is available in the public range, a new connection will use a mapping of an already mapped public IP address with a different port number. 7. On R9, configure loopback1 with an IP address of 11.1.9.9/24. 11.1.9.0/24 is the inside network, 100.1.69.0/24 is the outside network. 8. On R9, configure a dynamic PAT that maps the internal range 11.1.9.0/24 to the interface E0/0. 9. On R8, enable the TCP small server service on TCP port 13 called “datetime”. 10. On R8, configure a default route towards R6. 100.1.68.0/24 is the inside network, 100.1.69.0/24 is the outside network. Make sure that telnet from R9 to 100.1.69.30 on port 4000 will return the daytime information. 11. 10.1.108.0/24 is the inside network, 100.1.68.0/24 is the outside network. R1 should be able to reach R6 without configuring any static/default routes. You have to use the ip nat outside command on R8. 12. Ensure that you can telnet from R1 to R6 by using the “add-route” keyword in the NAT rule. 13. On R2, configure a default route towards R8. Traffic coming from R2 should be dynamically NATed to the IP address 100.1.68.20. Use a route-map to achieve this task.

Lab 45 Setup
This lab is intended to be used with online rack access. Connect to the terminal server for the online rack, and complete the configuration tasks as detailed below.
NOTE Load the initial configuration files before starting to work on the tasks.
Configuration Tasks 1. Setup R8 to collect Netflow version 9 statistics on E0/0 and E0/1, and to send them to server 10.1.79.33 on port 2333 in version 9 format. If R8 uses BGP, the peer AS should be included in exports. Make sure that the flows information is not duplicated. 2. Configure R8 to export flow records every 2 minutes. 3. On R8, ensure that a flow in the cache that was not refreshed during 10 seconds expires. 4. Setup R9 to collect Netflow version 9 statistics on E0/0 and E0/1, and to send them to server 10.1.79.33 on port 2333 in version 5 format. Only 1 out of 50 packets should be captured by Netflow, randomly. 271|P a g e

5. On R6, configure Netflow on interface E0/1 and interface E0/0 to only capture traffic between 10.1.8.8 and 10.1.9.9. Only 1 out of 2 packets from this flow should be captured. Use a class-map called “NETFLOWCLASS” and a policy-map called “NETFLOWPOLICY” 6. On R1, configure Netflow version 9 on interface E0/0 to capture Netflow statistics in egress and ingress directions. The Netflow template should be sent every minute in version 9 to server 10.1.79.44. 7. On R1, on the Netflow running on the E0/0, aggregate flow based of destination prefix present in the routing table. Never aggregate with a mask number lower than /24. 8. On R2, setup Netflow to display in the command line the 20 top speakers going through interface E0/0. Sort the top speaker by bytes. 9. On R7, configure Flexible Netflow to collect the source and destination IPv4 address, the flow direction, the next-hop IP address using a flow record called “IPEXPERTRECORD”. 10. On R7, configure Flexible Netflow to export statistics to the server 10.1.79.55 on port 3444 every 30 seconds using a flow exporter called “IPEXPERTEXPORTER”. 11. Activate Flexible NetFlow configuration in the ingress and egress direction on interface E0/1.
