Re: OT: Flapping eigrp interface

Hmmm... I think the problem might be on the other end as you are receiving
hellos (that brings up the adjacency) but for some reason you get no
acknowledge of the UPDATES you are sending (16 retransmissions, round 80
seconds).

If possible, do a debug eigrp packets on the other end and check if you are
getting the updates from your neighbor and what's the source IP and whether
you can reach it.
