ETHERNET TAG MAPPING IN VIRTUAL PRIVATE WIRE SERVICE USING ETHERNET VIRTUAL PRIVATE NETWORK

摘要

Presented herein is an exemplified system and method that facilitate a point-to-point (P2P) service operation, via EVPN VPWS service tunnels, between customer edge nodes and provider edge nodes in a network infrastructure (e.g., a MPLS infrastructure). In particular, the exemplified system and method employ an EVPN BGP construct that facilitates multiplexing across large number of different physical interfaces, among multiple device manufacturers and vendors, while reducing signaling among the nodes, and being fully supportive of EVPN capabilities. In an embodiment, a method is disclosed that establishes VPWS Service service-tunnels, which is associated with an Ethernet virtual private network (EVPN) Ethernet Auto-Discovery (EAD) route identifies the service tunnel as being a VPWS-ID service, a single tag service, or a double tag service.
