ECMP Round-Robin Mode Overview

Round-robin mode distributes packets equally among the available paths in the ECMP set.

If all the ECMP links are configured for the ip multipath round-robin command and their next hops are direct next hops, the round-robin mode uses the random algorithm for traffic distribution.

In round-robin mode, if a packet uses a path, the next packet can choose the same path or the previous path, or the next path based on the random value generated. The random algorithm does not guarantee equal distribution of the packets among the ECMP links.
