Hi All,
I have many L3 VLAN's in my Switch. But only one of the L3 VLAN is flapping, giving following error msg:
%DUAL-5-NBRCHANGE: EIGRP-IPv4:(186) 100: Neighbor 172.19.17.3 (Vlan17) is down: Interface PEER-TERMINATION received
%DUAL-5-NBRCHANGE: EIGRP-IPv4:(186) 100: Neighbor 172.19.17.3 (Vlan17) is up: new adjacency
Switch i am using is 4510R-E
All other VLAN is working fine. I have no idea how to troubleshoot this issue. Please guide me for this. Thanks in advance.
Regards

Were any changes/power outage/etc made that stopped this from working?

Hi Collin
Well no power outage happened, but one of the MAN link connected to the core switch flapped once.

Collin,
Can you please remove the /partner/ component from the URL to make the document publicly accessible without needing to log in?
Also, do you know what exactly is the Peer Termination in EIGRP? I know about Interface Goodbye but so far I have not encountered a Peer-Termination indication and I don't know what that can be good for.
Thanks!
Best regards,
Peter

Sorry about that, the CCO randomly logs me in and out.
