The objective of MC-LAG is to enhance both network availability and bandwidth utilization through various modes of traffic load balancing. RFC 7432 defines an EVPN-based MC-LAG with Single-Active and All-Active multihoming redundancy modes. This document builds on the existing redundancy mechanisms supported by EVPN and introduces a new active/standby redundancy mode, called 'Port-Active'.}, }
