   Provider Backbone Bridging (PBB) can be combined with Ethernet VPN
   (EVPN) to deploy ELAN services in very large MPLS networks (PBB-
   EVPN). Single-Active Multi-homing and per-ISID Load-Balancing can be
   provided to access devices and aggregation networks. In order to
   speed up the network convergence in case of failures on Single-Active
   Multi-Homed Ethernet Segments, PBB-EVPN defines a CMAC-Flush
   mechanism that works for different Ethernet Segment BMAC address
   allocation models. This document complements those CMAC-Flush
   procedures for cases in which no PBB-EVPN Ethernet Segments are
   defined (ESI 0) and an ISID-based CMAC-Flush granularity is desired.
