Objective
Learn to configure Enhanced Interior Gateway Routing Protocol (EIGRP) between multiple routers and verify routing tables.
Lab Topology
Task 1 - Basic Configuration & IP Addressing
R1 Configuration
Router(config)# hostname R1 R1(config)# interface GigabitEthernet0/0 R1(config-if)# ip address 172.16.10.1 255.255.255.252 R1(config-if)# no shutdown R1(config-if)# exit R1(config)# interface GigabitEthernet0/1 R1(config-if)# ip address 172.16.10.5 255.255.255.252 R1(config-if)# no shutdown R1(config-if)# exit R1(config)# interface Loopback1 R1(config-if)# ip address 10.10.10.1 255.255.255.0 R1(config)# interface Loopback2 R1(config-if)# ip address 10.10.11.1 255.255.255.0
R2 Configuration
Router(config)# hostname R2 R2(config)# interface GigabitEthernet0/0 R2(config-if)# ip address 172.16.10.6 255.255.255.252 R2(config-if)# no shutdown R2(config-if)# exit R2(config)# interface Loopback1 R2(config-if)# ip address 10.10.40.1 255.255.255.0 R2(config)# interface Loopback2 R2(config-if)# ip address 10.10.50.1 255.255.255.0
R3 Configuration
Router(config)# hostname R3 R3(config)# interface GigabitEthernet0/0 R3(config-if)# ip address 172.16.10.2 255.255.255.252 R3(config-if)# no shutdown R3(config-if)# exit R3(config)# interface Loopback1 R3(config-if)# ip address 10.10.20.1 255.255.255.0 R3(config)# interface Loopback2 R3(config-if)# ip address 10.10.30.1 255.255.255.0

R2 Configuration
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 Configuration
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
