Cisco Systems Cisco Systems Comcast Verizon Wireless Nokia The Multi-Chassis Link Aggregation Group (MC-LAG) 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. RFC7432 defines EVPN-based MC-LAG with Single-active and All-active multi-homing redundancy modes. This document builds on the existing redundancy mechanisms supported by EVPN and introduces a new active/standby redundancy mode, called 'Port-Active'.
