Hi guys,
Hi Jimmy! I have never seen this. Can you send me relevant parts of the BIRD configuration? And did you try to debug this protocol in BIRD? Ondrej
We have just moved 1 of our route server from OpenBGPd to BIRD this morning. However we were having issue bringing up 1 BGP session with our peering that is running ASR. We keep getting hold timer expired error. The BGP keep flapping every 2 minutes.
From the tcpdump, I can see we are getting destination unreachable due to destination host is administratively prohibited.
Have u guys encountered this issue? All other BGP with other peering are working ok. Below is the log from ASR..
