BGP from Juniper to Cisco ASR

Thu Dec 19 20:27:19 UTC 2013

I was able to solve the issue by statically routing the connected /29 out the connected interface, that way it overrode the BGP learned route for the same subnet (unfortunately this might have been a multi-homing issue that resulted in asymmetrical routing to the primary peer via the secondary peer, since the secondary peer session was already established). I thought BGP was "intelligent" enough to run the TCP session over the directly connected interfaces on the same subnets. I can understand this being an issue with multihop but not multi-homing.

When I had that problem, it was because the max-prefixes on the Juniper router was being triggered.   If I remember correctly.  It's a strange return message for the wrong issue.
