BGP route not received

‎12-18-2013 05:30 AM

Hi all,

 

this is my first job with BGP networks and I have the following issue. Wonder if you have any suggestions how to solve it. The network is configured IS-IS, BGP and is connected through MPLS VPN. I have Route Reflectors configured and fully meshed IBGP. A network that is directly connected to a route reflector client (LAN) is being advertised and received by the directly connected RR. This RR is then advetises this route to another RR, but this does not receive the route. To get a picture see the attached document. Why would this happen?

Hi there,

Do both RRs have one and the same cluster-id?

Thanks

Alex

Hi,

 

no they have different cluster IDs, but my understanding is this wouldn't affect this. Thanks

It should work. Can you paste a sample config and does your configuration look similar to this documentation?

Is 10.255.0.7 reachable on your RR2 ?

Show the BGP import polices configured on RR2. At a minimum RR2 should show what it is doing with the route.

RR2>show bgp neighbor RR1

Hi All, thanks for the replies. Still not sure what went wrong in here before, but it seems to be working all fine now. All routes have suddenly exchanged and received.. hmmm. must be the wonders of networks
