Configuring EIGRP

 Enable the EIGRP routing process:

R1#conf t

R1(config)#router eigrp 1

Advertise directly connected networks:

R1(config-router)#network 172.16.1.0 0.0.0.255

R1(config-router)#network 172.16.3.0 0.0.0.3

R1(config-router)#network 192.168.10.4 0.0.0.3

Disable automatic summarization:

R1(config-router)#no auto-summary

Configure passive interfaces:

R1(config-router)#passive-interface gigabitEthernet 0/0

Same as above for R2 & R3:

R2#conf t

R2(config)#router eigrp 1

R2(config-router)#network 172.16.2.0 0.0.0.255

R2(config-router)#network 192.168.10.8 0.0.0.3

R2(config-router)#network 172.16.3.0 0.0.0.3

R2(config-router)#

R2(config-router)#passive-interface gigabitEthernet 0/0

R3#conf t

R3(config)#router eigrp 1

R3(config-router)#network 192.168.10.8 0.0.0.3

R3(config-router)#network 192.168.10.4 0.0.0.3

R3(config-router)#network 192.168.1.0 0.0.0.255

R3(config-router)#no auto-summary

R3(config-router)#passive-interface gigabitEthernet 0/0
