This document describes how Ethernet Shortest Path Bridging MAC mode (SPBM) [IEEE.802.1Q] along with Provider Backbone Bridging Provider Edges (PBB PEs) and Provider Backbone Bridged Networks (PBBNs) can be supported by Ethernet VPNs (EVPNs) such that each SPBM island is operationally isolated while providing full L2 connectivity between the different types of PBBNs where desired. Each SPBM island uses its own control-plane instance and multipathing design, be it multiple equal-cost tree sets or multiple spanning trees.

   Support for Shortest Path Bridging MAC Mode over Ethernet VPN (EVPN)


   This document describes how Ethernet Shortest Path Bridging MAC mode    (SPBM) can be combined with Ethernet VPN (EVPN) to interwork with    Provider Backbone Bridging Provider Edges (PBB PEs) as described in    the PBB-EVPN solution (RFC 7623).  This is achieved via operational    isolation of each Ethernet network attached to an EVPN core while    supporting full interworking between the different variations of    Ethernet networks.
