I've tried searching around for this problem but haven't found much info.
We upgraded some 7301 routers the other night and there are a couple of
neighbors which have not been able to re-establish themselves.
Debugging from one of the routers shows this:
Nov 21 21:06:51.902 EST: BGP: Neighbor validation failed. Flags: 0x10,
Neighbor-topo check: passed, Router ID: 172.29.1.1
frorr01#
Nov 21 21:07:00.098 EST: BGP: Neighbor validation failed. Flags: 0x10,
Neighbor-topo check: passed, Router ID: 172.29.1.1

Nov 21 21:07:10.482 EST: BGP: Neighbor validation failed. Flags: 0x10,
Neighbor-topo check: passed, Router ID: 172.29.1.1
frorr01#
I've also seen some extra info in the "show ip bgp summary" command:
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ
Up/Down State/PfxRcd
172.29.2.1 4 20161 2 3 1 0 0
00:01:35 0 (SE)
Sometimes it's SE and other times it's SPE.
Any thoughts from anyone?
Thanks in advance.
Jose
