I am having difficulty maintaining my BGP session from my 6509 with
Sup-7203bxls to a 7206 VXR NPE-400. The session bounces every 3
minutes. I do have other IBGP sessions that are established with no
problems, however, this is the only IBGP peer that is bouncing
regularly.
What does exactly the message mean and how do I stabilize this? Any
help will be appreciated.
This is most likely an MTU problem. Your SYN/SYN+ACK goes thru, but then
the first fullsize MSS packet is sent, and it's not getting to the
destination. 3 minutes is the dead timer for keepalives, which are not
getting thru either because of the stalled TCP session.
