Static routes for ECMP applications

Equal-cost multipath routing (ECMP) is a routing strategy where next-hop packet forwarding to a single destination can occur over multiple "best paths." Each path has the same cost as the other paths, but a different next-hop router. In static routing, load-balancing can be achieved through ECMP. The following figure illustrates static routes applied to an ECMP topology.
