Case Study

LAN Principles (Networks and Routing) Case Study Handout

As per the Unit Outline - the Case Study makes up 10% of your final mark for this Unit. This is a group assignment, and must be completed by: • Groups of three students only • Groups assembled from students within the same allocated Lab Class Groups MUST be formed by Week 6. You are required to form your groups within the ESP (https://esp.it.swin.edu.au). The ESP web site is also used to lodge your assignment. Submission details for the assignment are outlined below. I. O UTLINE This Case Study will require you to 1) Build a small network using two routers 2) Add a second network attached to the exiting network consisting of a third router 3) Optionally combine the two seperate routing protocols to allow traffic to traverse between the two networks II. PART A The ACME corporation needs to build a small network as outlined in the network diagram below

A. Network Addressing Your Lab Supervisor will provide you with a network address and subnetting details regarding the number of hosts required by each LAN. When subnetting for this network you must: • Ensure that you have enough subnets to address the entire network • Subnet optimally such that the largest number of IP addresses within your allocated network remain for future expansion Version 3 (February 2010)

B. Router Configuration You are required to configure the two routers with the following information: • Router names • Message of the Day • Interface descriptions • Host Tables • Telnet Access • All interfaces are to have the lowest usable IP address of their subnet allocated • For the serial link between the routers, ACME R1 should have the lowest usable IP address of the allocated subnet and ACME R2 should us the next lowest usable address When allocating the LAN subnets to interfaces on the router you should allocate the lans as follows: • ACME LAN1: FastEthernet0/0 • ACME LAN2: lo0 • ACME LAN3: FastEthernet0/0 • ACME LAN4: lo0 You may choose whichever serial interface you like on the router to suit the hardware configuration, however be sure to document your choices. C. Routing The ACME network should configure its routing tables using the RIP routing protocol to support your VLSM subnetting scheme. You need to configure the routers such that the network routes are properly advertised. D. Testing To 1) 2) 3) 4)

properly test your configuration you should be able to: See the two LAN networks on the ACME R1 router appear in the routing table on ACME R2 See the two LAN networks on the ACME R2 router appear in the routing table on ACME R1 Be able to ping all the ACME addresses from the PC on ACME LAN1 Be able to ping all the ACME addresses from the PC on ACME LAN3 III. PART B

The OMEGA corporation has been acquired by ACME and is planning to attache its network to the network used by ACME. OMEGE has established a site (LAN) where the ACME R1 router is located. The new network details are outlined in the network diagram on the next page. The new network consists of three LANs attached to the OMEGA R1 router and one LAN attached to ACME R1 A. Network Addressing Your Lab Supervisor will provide you with a network address and subnetting details regarding the number of hosts required by each LAN in the OMEGA network. When subnetting for this network you must: • Ensure that you have enough subnets to address the entire network • Subnet optimally such that the largest number of IP addresses within your allocated network remain for future expansion B. Router Configuration You are required to configure the OMEGA R1 router (and update the configuration of the ACME routers) with the following information: • Router names • Message of the Day • Interface descriptions • Host Tables • Telnet Access • All interfaces are to have the lowest usable IP address of their subnet allocated • For the serial link between the routers, OMEGA R1 should have the lowest usable IP address of the allocated subnet and OMEGA R2 should us the next lowest usable address

When allocating the LAN subnets to interfaces on the router you should allocate the lans as follows: • OMEGA LAN1: lo1 • OMEGA LAN2: FastEthernet0/0 • OMEGA LAN3: lo0 • OMEGA LAN4: lo1 You may choose whichever serial interface you like on the router to suit the hardware configuration, however be sure to document your choices. C. Routing The OMEGA network should configure its routing tables using the EIGRP routing protocol. You need to configure the routers such that the network routes are properly advertised. D. Testing To 1) 2) 3)

properly test your configuration you should be able to: See the three LAN networks on the OMEGA R1 router appear in the routing table on ACME R1 See the LAN network on the ACME R1 router appear in the routing table on OMEGA R1 Be able to ping all the OMEGA addresses from the PC on OMEGA LAN2 IV. PART C

This work is optional and can be used to earn bonus marks. Be aware that while the bonus marks can be used to increase your Case Study score where you lost marks in other parts of the Case Study, it is not possible to score greater than 100% for the Case Study. The two networks (ACME and OMEGA) need to be merged such that all devices in any ACME LAN can now access all devices in any OMEGA LAN. A. Routing You need to configure the routing proocols on the routers such that the ACME network is propagated into the EIGRP routing protocol and that the OMEGA network is propagated into the RIP routing protocol.

B. Testing To properly test your system you should be able to ping all of the ACME and OMEGA addresses from any PC on either the ACME or OMEGA LANs V. A SSESSMENT The assessment component for the Case Study is based entirely on a written report. The report is a group report and must be submitted via the ESP web site by the due date of 5:00pm on Wednesday during Week 11. This section outlines what you must include in your report and how the report will be graded. Note: The router output component mark is based on the output captured from real routers. Output from a simulator will receive a mark of zero for this component. Use of NetLab is acceptable as NetLab consists of real routers. A. Report Contents You are required to produce a report that contains the following information. Subnetting Discussion A discussion of your subnetting approach, why particular subnet masks were chosen and how you allocated the subnets to individual networks Network Drawing A complete network drawing detailing allocation of addressing information for all relevant hosts and devices Router Configuration Tables Tables containing the final configuration information for all three routers. Including: • Hostname information • Network address/subnet-mask allocations • Descriptions/MOTD • Host-table entries • Telnet access and password information • Routing protocol statements Your required router configuration table should look like the table below: ACME R1 ACME R2 Hostname Console Password Secret Password VTY Password Serial 0/0 IP Address/Subnet Mask Serial 0/0 Clockrate Serial 0/0 Description Serial 0/1 IP Address/Subnet Mask Serial 0/1 Clockrate Serial 0/1 Description FastEthernet 0/0 IP Address/Subnet Mask Loopback 0 IP Address/Subnet Mask Loopback 0 Description Loopback 1 IP Address/Subnet Mask Loopback 1 Description Interfaces to Enable Routing Protocols Enabled Routing Protocol Statements Host Table Entries Message of the Day Routing Protocol Discussion A discussion on how and why you configured your routing protocols in the way you did Router Output A copy of the output of the following commands on all routers: show version show run
