Hi Pavan
Thanks for the reply. Actually I am using the the physical gig interfaces with vlan-tagging to connect all the routers. i do not have any lt interfaces. What exactly I observed that:
The PE to CE subnet is not advertised by MBGP (if PE to CE interface is broadcast interface) unless I used the vrf-table-label command OR run BGP or any other static/IGP protocol with CE so that PE to CE subnet is the nexthop for some routes then PE-CE subnet is advertised without vrf-tabel-label. I saw one KB about this behavour which is KB12430 and now I can understand this behaviour.
But my question is that when I used vrf-tabel-label to advertise the PE-CE subnet through MBGP without running any static/IGP/BGP from PE to CE then I am unable to ping the PE-CE interface IP from the remote PE.
Could you please check this for me. Really appreciated your help.
Thanks
