Inter-Provider VPN using ASBR-ASBR


We have Inter-Provider VPN setup where two ASs are connected using ASBR-ASBR running EBGP and each AS has multiple PEs and customer VRFs. We recently migrated our AAA VRF from AS1 to AS2, the VRFs residing on the ASBR/PEs in both ASs are able to talk to the AAA VRF but not the VRFs on the other PEs connecting to the ASBRs which have the next hop self for its peers.

All routing has been confirmed and are learnt via importing of route-target.

Any help would be greatly appreciated.

Could you please explain the case in detail.

Re: Inter-Provider VPN using ASBR-ASBR

Hi Guruparsad,

Thanks for the response, I had to log a TAC case as it was affecting quite a number of our customers, it was a connectivity issue between the VRFs in different AS and there was connectivity for some VRFs but not for the others. Basically the LFIB wasn't getting populated, the LIB and routing table were getting populated but not the LFIB.

Cisco engineers believe it could be a bug but they couldn't pin point it.
