Section 2: IP IGP Protocols (30 Points)

Configure the IP routing as illustrated in Figure 6-10, following the directions.

Figure 6-10. IP IGP Diagram

Section 2.1: OSPF (10 Points)

• Configure OSPF according to Figure 6-10. 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 and Sw1-interface VLAN 11 are to be configured as OSPF area 11.

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

• Configure the loopback addresses to be part of the OSPF process. These interfaces should appear in the OSPF routing table with their original /24 mask.

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

• Configure R1 such that the interface on VLAN_25 will have a cost of 20.

Section 2.2: EIGRP (8 Points)

Configure EIGRP between R2 and BB1. Configure EIGRP as AS 400. 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.

Redistribute mutually between EIGRP and OSPF. Make sure all routers have the EIGRP routes in their routing tables.

Configure R2 to allow only the networks 50.5.5.0/24 and 40.4.4.0/24 from BB1.

You want to guarantee a minimum of 70 percent of the bandwidth for the EIGRP traffic. Configure R2 to accommodate this.

Section 2.3: RIP (7 Points)

• Configure RIPv2 between R4 and BB2. R4-e0/0 must be the only interface configured for RIP on R4. You should receive updates and the R4 routing table will be populated with some RIP routes from BB2.

• Redistribute RIP into OSPF such that networks 20.0.0.0/8 and 30.0.0.0/8 will have a metric of 128 kbps and network 196.1.0.0/16 will have a metric of 56 kbps.

• Configure R4 to adjust RIP timers so the time that a route is declared invalid will be set to 200 seconds.

Section 2.4: IS-IS (5 Points)

• Configure IS-IS according to Figure 6-10. R3-fa0/0, R3-fa0/1, R5-fa0/0, R6-e0/0, and the ISDN cloud are part of the IS-IS domain. Use area 49.0004 and level 1 and 2 adjacencies.

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

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

• Redistribute IS-IS into OSPF on R5. R6 should see in its routing table all routes from your topology and R6 must be able to ping all other router loopback0 address.

• To avoid overloading the CPU of the IS-IS routers on VLAN_22 during LSP transmission and reception, configure the routers to reduce the LSP transmission rate to 100 ms.
