Abstract:
A method of establishing a multi-segment pseudowire (MS-PW) across domains executing different pseudowire signaling protocols augments a Label Distribution Protocol (LDP) label message to include a MS-PW Type-Length-Value (TLV). The MS-PW TLV carries pseudowire signal protocol information associated with signaling protocols of other segments of the MS-PW. As a result, a multi-segment pseudowire can be extended between domains that execute different pseudowire signaling protocols.
