That combination is what we refer to as PBB-EVPN. Single- Active Multi-homing and per-I-SID (per Service Instance Identifier) 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 (ES), PBB- EVPN defines a flush mechanism for Customer MACs (C-MAC-flush) that works for different Ethernet Segment Backbone MAC (B-MAC) address allocation models. This document complements those C-MAC-flush procedures for cases in which no PBB-EVPN Ethernet Segments are defined (the attachment circuit is associated to a zero Ethernet Segment Identifier) and a Service Instance Identifier based (I-SID- based) C-MAC-flush granularity is required.}, }
