Why got 2 x IP-EIGRP neighbors for process?

[Ken Lee]

Hi All,

Something weird. Just want to seek expert advise here. I have eigrp  AS number 4 running but somehow another AS Number 5 pop out nowhere.

So, how can i determine if this is a problem or it is fine with this? There isn't any entries in the process 5. The only change was Eigrp router-id to point back to the Core Switch 1 loopback IP address as previously it was pointing to the wrong loopback IP.

Hello Ken,

Is it by any means possible that you have a router eigrp 5 section in your configuration, or that it has been there at some point in the past? Alternatively, are you using any VRFs and running EIGRP in those?

It would be helpful if you posted your configuration.

Best regards,

Peter
