Packet Pseudowire Encapsulation over an MPLS PSN
This document describes a pseudowire that is used to transport a packet service over an MPLS PSN is the case where the client LSR and the server PE are co-resident in the same equipment. For correct operation these clients require a multi-protocol interface with fate sharing between the client protocol suite. The packet pseudowire may be used to carry all of the required layer 2 and layer 3 protocols between the pair of client LSRs.
