Abstract

[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)

Abstract

   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.
