With Equal Cost Multipath (ECMP), the switch can determine equal-cost paths to the same destination prefix. You can use multiple paths for load sharing of traffic. These multiple paths allow faster convergence to other active paths in case of network failure. By maximizing load sharing among equal-cost paths, you can use your links between routers more efficiently when sending IP traffic. ECMP is formed using routes from the same source or protocol, and the ECMP routes are evaluated within each routing protocol.

The ECMP feature supports and complements the following protocols and route types:

• OSPFv3

• Static routes

• BGP+

• RIPng

• IPv6 Shortcuts
