***Network Topology for EIGRP Configuration***

R1 Router

R1>enable
Enters privileged mode.

R1#config t
Moves to global configuration mode.

R1(config)#router eigrp ConfigEG
Creates a named EIGRP virtual instance called ConfigEG.

R1(config-router)#address family ipv4 autonomous-system 1
Enables the IPv4 address family and starts EIGRP autonomous system 1.

R1(config-router-af)#network 10.1.1.0
