>> Now I am trying to extend these L2 circuits to anther MPLS Domain where we have direct Gigabit fibre connection I am using the same concept and establish ospf peering on the ASBR router with the remote ASN and redistributed my IGP so my loopbacks are seen by the PEs on both sides of the domains and establish ldp peering how ever the l2circuit is not coming up any help is appriciated as I have been working on this more than 24hrs and think that i am now a bit clouded
