Provider Backbone Bridging Combined with Ethernet VPN
RFC 7623, “Provider Backbone Bridging Combined with Ethernet VPN”, is a Proposed Standard document published in September 2015 by A. Sajassi, S. Salam, N. Bitar, A. Isaac, W. Henderickx. The canonical text is published by the RFC Editor.
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
