Hi Dishan ,
Pls cc SP group for question like this ... Many people who are preparing for
CCIE SP might not be viewing the alias.
Ok Coming back to your question. I think your MPLS connectivity might have
got broken at the ASBRs. Pls provide the following for more analysis.
1) I could see you are using option 2 in Inter AS VPN ( VPNV4 enabled ASBR ).
However it is not clear whether you are using next-hop-self on the ASBR . If
you are not using next-hop-self... then probably you must be redistributing
the the connected routes in your IGP @ ASBR. could you pls confirm this.
2) Also pls provide the following a) sh ip bgp vpn all label b) sh mpls
forwarding c) sh ip cef vrf <vrf name> <any prefix on the remote ce> ( this
should taken from both PEs)
Thanks and Regards
Arun
