Forwarding of L2 protocols instead of tunneling can be easily done. The L2 protocols dst-mac is buried under a number of labels (transport and vc) and another ethernet II header, I don't see why this would be punted to the LSR's CPU in a mpls switched backbone, even if not "tunneled" (where tunneling means dst-mac rewriting). Not sure if I got your point correctly though? _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
