Are you asking for a command that ONLY shows routes from a certain neighbour? if so then I know of no command, and I just dump in a excel sheet and filter out everything else.


Are you asking to which neighbour a packet will go when being routed? if so the simple

sh ip route x.x.x.x

will show that.

hope this helps

Basically it depends on the routing protocol that is used.

For example, it will be "Router#show ip ospf neighbour", if it has configured with OSPF.

The "show ip ospf neighbor" command is just going go show you information about your neighbors such as the IP address of the neighbor etc. If you type "show ip route" look for where it says VIA.

For Example via Which means the network was learned from If yo have multiple networks which which advertised from 20.1 you can also see those.

Hi Dan,

It depends of the routing protocol:


debug ip rip


- debug ip EIGRP but you need to clear the session

- sh ip eigrp topology


You need to check per LSA type:

sh ip ospf database adv-router


If you want to know all the prefixes you received before your inbound filtering policy filters them, you need the soft-configuration inbound feature:


The use the show ip bgp neighbor x.x.x.x received-route command

I've just notice the title focus on EIGRP only ;-) but didn't want to remove all I wrote in case it may help others.
