ECMP routing allows multiple entries for routes to the same destination. Each path has the same cost as the other paths, but a different next-hop router. The ip load-sharing
command specifies the maximum number of equal paths that can be configured. Values range from 2 to 4.
An ECMP set with the same destination but different next-hop routers shows configuration of an ECMP set with two different gateways to the same destination address but through different next-hop routers.
