is up: new adjacency
Let?s configure all the network commands so all routers become EIGRP neighbors and advertise
their networks:
R1(config)#router eigrp 1 R1(config-router)#network 192.168.12.0 R3(config)#router eigrp 1 R3(config-router)#network 192.168.34.0 R2(config)#router eigrp 1 R2(config-router)#no auto-summary R2(config-router)#network 192.168.12.0 R2(config-router)#network 192.168.24.0 R4(config)#router eigrp 1 R4(config-router)#no auto-summary R4(config-router)#network 192.168.24.0 R4(config-router)#network 192.168.34.0 R4(config-router)#network 4.0.0.0
Check show ip eigrp neighbors on all the devices,
R1#show ip route eigrp
4.0.0.0/24 is subnetted, 1 subnets
