WebApr 3, 2024 · To perform load-balancing of GRE traffic in transit routers, a transit node distributes incoming GRE traffic evenly across all available ECMP links in a GRE tunnel topology. Furthermore, to determine traffic entropy, a hashing function uses GRE outer and inner header tuples such as source IP, destination IP, protocol, and router ID. WebEqual-Cost Multi-Path (ECMP) is a forwarding mechanism for routing packets along multiple paths of equal cost with the goal to achieve almost equally distributed link load sharing. This, of course, significantly impacts a router's next-hop (path) decision.
