Hello,
It is somethink that I don't know very well...
- I have two 4500-x configured in VSS mode
- The Vss is connected by tow link to my backbone
- I use eBGP between the VSS ans ME-3800-X1 and ME-3800X2.
4500X1-VSS <int A----------------------->ME-3800X1-AS65002----------Backbone---|
4500X2-VSS <intB----------------------->ME-3800X2-AS65002-----------Backbone --|net 10.160.254.59/29
When Int A /B are up > the fib is ok.
I can see 10.160.254.59/29 by ME-3800X1-AS65002 and ME-3800X2-AS65002.
When I put down the interface A, the route to 10.160.254.59/29 is to Int B, after the Hold time , it's 15s(keepalive 5s)
It's Ok for me.
But When I reload the 4500X2 by "redundancy force-switchover", I lost all route.
All connection are reset.
My configuration in VSS :
sw-4500x-vss#sh run | sec bgp
router bgp 65002
bgp log-neighbor-changes
bgp graceful-restart restart-time 120
bgp graceful-restart stalepath-time 360
