Objective
Learn to configure Enhanced Interior Gateway Routing Protocol (EIGRP) between multiple routers and verify routing tables.
Lab Topology
Task 1 – Loopback Interface Configuration
R1 Loopbacks
R1(config)# int loopback 1 R1(config-if)# ip address 10.10.10.1 255.255.255.0 R1(config)# int loopback 2 R1(config-if)# ip address 10.10.11.1 255.255.255.0
R2 Loopbacks
R2(config)# int loopback 1 R2(config-if)# ip address 10.10.40.1 255.255.255.0 R2(config)# int loopback 2 R2(config-if)# ip address 10.10.50.1 255.255.255.0
R3 Loopbacks
R3(config)# int loopback 1 R3(config-if)# ip address 10.10.20.1 255.255.255.0 R3(config)# int loopback 2 R3(config-if)# ip address 10.10.30.1 255.255.255.0
Task 2 – EIGRP Configuration (AS 1)
R1
R1(config)# router eigrp 1 R1(config-router)# network 10.10.10.0 R1(config-router)# network 10.10.11.0 R1(config-router)# network 172.16.10.0 R1(config-router)# network 172.16.10.4 R1(config-router)# no auto-summary
R2
R2(config)# router eigrp 1 R2(config-router)# network 172.16.10.4 R2(config-router)# network 10.10.40.0 R2(config-router)# network 10.10.50.0 R2(config-router)# no auto-summary
R3
R3(config)# router eigrp 1 R3(config-router)# network 172.16.10.0 R3(config-router)# network 10.10.20.0 R3(config-router)# network 10.10.30.0 R3(config-router)# no auto-summary
Task 3 – Verification
R1# show ip route R2# show ip route R3# show ip route
