Part 2: Implement EIGRP for IPv4

In this part, you will configure classic EIGRP for IPv4 and verify that all routing tables are converged.

Step 1: Configure classic EIGRP for IPv4.

Configure classic EIGRP for IPv4 on all devices. Use Autonomous System number 98, and advertise only the connected interfaces on each device.

R1# config t

Enter configuration commands, one per line. End with CNTL/Z.

R1(config)# router eigrp 98

R1(config-router)# network 10.12.0.0 0.0.0.255

R1(config-router)# network 10.13.0.0 0.0.0.255

R1(config-router)# network 192.168.3.0 0.0.0.255

R1(config-router)# exit

R1(config)# end

R2# config t

Enter configuration commands, one per line. End with CNTL/Z.

R2(config)# router eigrp 98

R2(config-router)# network 10.12.0.0 0.0.0.255

R2(config-router)# network 10.23.0.0 0.0.0.255

R2(config-router)# exit

R2(config)# end

R3# config t

Enter configuration commands, one per line. End with CNTL/Z.

R3(config)# router eigrp 98

R3(config-router)# network 10.23.0.0 0.0.0.255

R3(config-router)# network 10.13.0.0 0.0.0.255

R3(config-router)# network 172.16.3.0 0.0.0.255

R3(config-router)# exit

R3(config)# end

D1# config t

Enter configuration commands, one per line. End with CNTL/Z.

D1(config)# router eigrp 98

D1(config-router)# network 192.168.3.0 0.0.0.255

D1(config-router)# network 192.168.2.0 0.0.0.255

D1(config-router)# network 192.168.1.0 0.0.0.255

D1(config-router)# network 192.168.0.0 0.0.0.255

D1(config-router)# exit

D1(config)# end

Step 2: Verify EIGRP for IPv4 routing.

Verify that each device has a complete routing table for all the networks shown in the topology and Addressing Table.
