[RFC7432] introduces a solution for multipoint Layer 2 Virtual Private Network (L2VPN) services, with advanced multihoming capabilities, using BGP for distributing customer/client MAC address reachability information over the core MPLS/IP network. [PBB] defines an architecture for Ethernet Provider Backbone Bridging (PBB), where MAC tunneling is employed to improve service instance and MAC address scalability in Ethernet as well as VPLS networks [RFC7080].

     Provider Backbone Bridging Combined with Ethernet VPN (PBB-EVPN)


   This document discusses how Ethernet Provider Backbone Bridging (PBB)    can be combined with Ethernet VPN (EVPN) in order to reduce the    number of BGP MAC Advertisement routes by aggregating Customer/Client    MAC (C-MAC) addresses via Provider Backbone MAC (B-MAC) address,    provide client MAC address mobility using C-MAC aggregation, confine    the scope of C-MAC learning to only active flows, offer per-site    policies, and avoid C-MAC address flushing on topology changes.  The    combined solution is referred to as PBB-EVPN.
