As observed above, MANILA router can reach both the MELBOURNE and SINGAPORE routers
Now, let’s configure EIGRP on the HUB and Spoke Routers:
On MANILA router, I have created a loopback address for the 4 network segments which I’m planning to propagate to both MELBOURNE and SINGAPORE routers.
MANILA(config)#int lo1
MANILA(config-if)#ip add 100.100.1.1 255.255.255.0
MANILA(config-if)#int lo2
MANILA(config-if)#ip add 100.100.1.1 255.255.255.0
MANILA(config-if)#int lo3
MANILA(config-if)#ip add 100.100.3.1 255.255.255.0
MANILA(config-if)#int lo4
MANILA(config-if)#ip add 100.100.4.1 255.255.255.0
I have enabled EIGRP on MANILA router and added into EIGRP networks the segments to MANILA and SINGAPORE. I have propagated as well the 4 network address as seen below,
MANILA(config)#router eigrp 123
MANILA(config-router)#network 192.168.12.0
MANILA(config-router)#network 192.168.13.0
MANILA(config-router)#network 100.100.1.0 0.0.0.255
MANILA(config-router)#network 100.100.2.0 0.0.0.255
MANILA(config-router)#network 100.100.3.0 0.0.0.255
MANILA(config-router)#network 100.100.4.0 0.0.0.255
MANILA(config-router)#no auto-summary <— required to disabled auto-summary of the networks
Configuring EIGRP on both MELBOURNE and SINGAPORE Router:
MELBOURNE(config)#router eigrp 123
MELBOURNE(config-router)#network 192.168.12.0
MELBOURNE(config-router)#no auto-summary
*Jul 12 14:27:24.967: %DUAL-5-NBRCHANGE: EIGRP-IPv4 123: Neighbor 192.168.12.1 (Serial4/0.21) is up: new adjacency
SINGAPORE(config)#router eigrp 123
SINGAPORE(config-router)#network 192.168.13.0SINGAPORE(config-router)#no auto-summary
*Jul 12 14:28:01.507: %DUAL-5-NBRCHANGE: EIGRP-IPv4 123: Neighbor 192.168.13.1 (Serial3/0.31) is up: new adjacency
The moment that I have enabled EIGRP and add the network statement on both MANILA and SINGAPORE router, neighbor adjacency were formed as seen from console below,
MANILA(config-if)#
*Jul 12 14:27:24.931: %DUAL-5-NBRCHANGE: EIGRP-IPv4 123: Neighbor 192.168.12.2 (Serial3/0.12) is up: new adjacency
*Jul 12 14:28:01.351: %DUAL-5-NBRCHANGE: EIGRP-IPv4 123: Neighbor 192.168.13.2 (Serial3/0.13) is up: new adjacency
VERIFICATIONS FOR THE EIGRP CONFIGURATIONS:
1. Neighbor Table shows that MANILA have formed the neighbor with both SINGAPORE and MELBOURNE router.
