The Multi-Chassis Link Aggregation (MC-LAG) group technology enables
establishing a logical link-aggregation connection with a redundant
group of independent nodes. 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'.
This document is a product of the BGP Enabled ServiceS Working Group of the
IETF.
This is now a Proposed Standard.
