I have an existing MPLS Pseudowire connection that I need to rework to be able to carry vlan tags instead of just plain L2 frames.
ME3400 <-> 7206VXR <-> 7206VXR <-> ME3400
The ME3400's customer facing int tags incoming frames, which go over a trunk interface to a 7206VXR subint. The subint is conf'd for pseudowire p2p to the remote 7206VXR which has an identical setup. Subint on a trunk int to a ME3400, cust facing int tied to a matching vlan.
My thought is use QinQ on the switches, with the question being will the 7206s correctly strip off one vlan tag layer, encapsulate the remaining vlan tagged L2 frame for psuedowire, and on the remote end take the pesuedowire packet, decapsulate it, add on the QinQ tag, and shove it back out to the switch? I won't know ahead of time what vlan tags the customer will be looking to pass, so I need to be able to support whatever they try to throw across this link.
