Abstract
Systems and methods for interconnecting heterogeneous layer 2 virtual private network applications. To facilitate such interconnections, a common addressing scheme for forwarders is provided. All current pseudowire signaling protocols can incorporate this addressing scheme, and therefore establish connectivity among forwarders of different applications. Auto-discovery of remote forwarders is also facilitated by use of a common address family identifier (and subsequent address family identifier) for BGP.
