am dealing with a a BGP flap issue, and looked at pretty much all what I can think of.
outQ is not able to drop to zero, this is on a Route reflector which has 2 legs to a distribution switch. IGP used is IS-IS, platform is 7301.
Since it is a Reflector, it has many BGP sessions. all sessions are behaving as expected....except the one to the primary reflector.
I checked for L2 issues, MTU issues. I have no QOS, nor do I see need for it. since its a reflector no much traffic carried on Ge ports.
extended pings between loopbacks works fine, no drops. and load balancing is per destination.
I got fiber switched, connectors changed, disabled one the redundant legs to stop load balancing.
as you can see, I have pretty much been thru all what I can think off. so any suggestions are appreciated !
