EVPN Multi-Homing Mechanism for Layer-2 Gateway Protocols
Existing EVPN multi-homing schemes are limited to Single-Active and All-Active as per RFC-7432. Neither of these multi-homing mechanisms are sufficient to support access networks with Layer-2 Gateway protocols such as MST-AG, REP-AG, and G.8032. These Layer-2 Gateway protocols require a new multi-homing mechanism defined in this draft.
