Router# Show ip eigrp neighbors

This command lists the neighbors which are part of the same autonomous number, you can check if the routers that are required to be in EIGRP are establishing the neighbor relation.

Topology table in the EIRGP identifies the best path called Successor and the alternate path called the feasible successor. To verify if the routes are exchanged between the EIGRP process, run the following command to check the topology table.

Router # show ip eigrp topology

The active route to any network or the best path to a network exists in routing table. To check the routes are present in the routing table you can use the following command

Router # show ip route

This will list all the routes in the routing table. To reduce or filter the routes learned by EIGRP use the following command.

Router # show ip route eigrp

To verify the EIRGP traffic is exchanged between the routers running EIGRP and the timers for the hello messages following commands are used.

Router # show ip protocols

This shows the timers for the hello messages, the autonomous number of the EIGRP process and eigrp neighbors.

Router # show ip eigrp traffic

The above command list the amount and type of EIGRP messages exchanged between the routers.

Router # show ip eigrp interfaces
