Section 2: IP IGP Protocols (30 Points)


Configure the IP routing as illustrated in Figure 5-10, following the directions.

Section 2.1: OSPF (10 Points)

  • Configure OSPF according to Figure 5-10. R1-s0/1, R2-s0/1, R4-s0/1, and R5-s0/1 are to be part of the OSPF area 0.

  • R2-s0/0 and R3-s0/0 are to be configured as OSPF area 1.

  • R1-e0/0 is to be configured as OSPF area 11.

  • R1-e0/1 and R5 fa0/1 are to be configured as OSPF area 25.

If you configured this correctly as shown in Example 5-19 through Example 5-23, you have scored 5 points.

  • Configure the loopback addresses to be part of the OSPF process

If you configured this correctly as shown in Example 5-19 through Example 5-23, you have scored 3 points.

  • Make sure you are able to ping any OSPF interface from any router.

If you configured this correctly as shown in Example 5-19 through Example 5-23, you have scored 2 points.

This is a basic OSPF configuration. The idea is to make you more familiar with the OSPF configuration to go to a more complex environment in the next Lab exercise Chapter 6 "Practice Lab 6."

Although the question did not specify how the Loopback masks should appear up on the OSPF routing tables, the following examples show the Loopback address configured with ip ospf network point-to-point so the address mask will shown up as /24. Without this, commands the address will show up as /32.

Also, an important thing to observe is that you do not need any virtual link because all ABR routers are connected to area 0.

Section 2.2: EIGRP (8 Points)

  • Configure EIGRP between R2 and the BB1. R2-fa0/0 must be the only interface configured for EIGRP on R2. The R2 routing table should be populated with EIGRP routes from BB1.

If you configured this correctly as shown in Example 5-24, you have scored 3 points.

  • On R2, redistribute EIGRP into OSPF mutually. Make sure all routers have the EIGRP routes in their routing tables.

If you configured this correctly as shown in Example 5-24, you have scored 3 points.

This is a basic setup to have R2 receiving EIGRP routes from BB1. An important thing is to observe the EIGRP AS number is given in the IP IGP diagram in Figure 5-10. You must follow it. Pay attention when configuring the redistribution to explore the redistribute command to make sure no networks will be missing.

Example 5-24 shows the necessary commands to configure the question's requirement as well as the output from the R2 and BB_Router routing tables.

NOTE

To have R2 to advertise the OSPF networks to BB1, you need to configure under the EIGRP process the network 160.10.0.0 or the redistribution of OSPF into EIGRP.

  • Configure R2 to receive only advertisements from BB1 for networks 193.118.1.0, 193.118.2.0, and 193.118.3.0. Use a minimum number of commands to accomplish this task.

If you configured this correctly as shown in Example 5-25, you have scored 2 points.

You can accomplish this using a minimum number of commands by using a one-line access list manipulating the wildcard bits and applying with a distribute list.

Example 5-25 shows the access list and the distribute list con.gurations and the updated routing table after the commands have been applied.

Section 2.3: RIP (7 Points)

  • Configure RIP between R4 and BB2. R4-e0/0 must be the only interface configured for RIP on R4. You should receive updates and R4 routing table will be populated with some RIP routes from BB2.

If you configured this correctly as shown in Example 5-26, you have scored 3 points.

  • Configure on R4 a filter that will allow only networks 196.1.2.0, 196.1.8.0, and 196.1.10.0 on R2 from BB2. Use an ACL with a minimal number of lines.

If you configured this correctly as shown in Example 5-26, you have scored 2 points.

  • Redistribute RIP into OSPF. Make sure all other routers have those three networks in their routing tables.

If you configured this correctly as shown in Example 5-26, you have scored 2 points.

RIP V.2 is running on BB2 and advertising routes to R4. A filter and redistribution into OSPF is used to accomplish this task. Here we are also exercising the possibilities of wildcard mask.

Section 2.4: IS-IS (5 Points)

  • Configure IS-IS according to Figure 5-10. R3-fa0/0, R3-fa0/1, R5-fa0/1, R6-e0/0 and the ISDN cloud are part of the IS-IS domain. Use area 49.0004 and only level 2 adjacencies.

  • You should have the RT of all IS-IS routers populated with the IS-IS networks.

  • You should be able to ping all interfaces of all routers under the IS-IS network.

If you configured this correctly as shown in Example 5-27, you have scored 3 points.

  • Redistribute IS-IS into OSPF on R5. In its routing table, R6 should see all routes from your topology.

If you configured this correctly as shown in Example 5-27, you have scored 2 points.

This is a basic IS-IS configuration into a single area. It is a good idea to configure your R6-loopback address under IS-IS because R6 is running only IS-IS, and you might need later to have R6-lo0 be reachable.

Example 5-27 shows the IS-IS configuration, and the important commands to enable the IS-IS are also highlighted. Notice you need to add the ip router isis command to the router interfaces and the isis circuit-type command also to the interfaces that are participating on the IS-IS process. The clns routing command is not necessary if you do not have CLNS traffic. You are configuring here to show the behavior under the ISDN scenario later. Also, an alternative solution to configure the circuit-type desired is on the IS-IS routing process instead of to the interface. To redistribute IS-IS into OSPF on R5, use the redistribute connected command within the OSPF process to force advertisement of the 160.10.22.0/24 network into OSPF.
