Equal-Cost Multipath, or ECMP, is a routing technique that allows a router or Layer 3 switch to use multiple paths toward the same destination when those paths have equivalent routing costs. Instead of forcing all traffic through a single best route, ECMP can create a set of valid next hops and distribute network flows across…
