    abstract =  {This document describes a pseudowire mechanism that is used to transport a packet service over an MPLS PSN in the case where the client Label Switching Router (LSR) and the server Provider Edge equipments are co-resident in the same equipment. This pseudowire mechanism may be used to carry all of the required layer 2 and layer 3 protocols between the pair of client LSRs. {[}STANDARDS-TRACK{]}},
