            Seamless Integration of Ethernet VPN (EVPN) with
                 Virtual Private LAN Service (VPLS) and
            Their Provider Backbone Bridge (PBB) Equivalents

Abstract

   This document specifies mechanisms for backward compatibility of
   Ethernet VPN (EVPN) and Provider Backbone Bridge Ethernet VPN
   (PBB-EVPN) solutions with Virtual Private LAN Service (VPLS) and
   Provider Backbone Bridge VPLS (PBB-VPLS) solutions.  It also provides
   mechanisms for the seamless integration of these two technologies in
   the same MPLS/IP network on a per-VPN-instance basis.  Implementation
   of this document enables service providers to introduce EVPN/PBB-EVPN
   Provider Edges (PEs) in their brownfield deployments of VPLS/PBB-VPLS
   networks.  This document specifies the control-plane and forwarding
   behavior needed for the auto-discovery of the following: 1) a VPN
   instance, 2) multicast and unicast operation, and 3) a Media Access
   Control (MAC) mobility operation.  This enables seamless integration
   between EVPN and VPLS PEs as well as between PBB-VPLS and PBB-EVPN
   PEs.
