Equal Cost MultiPath (ECMP)

The Equal Cost MultiPath (ECMP) feature allows routers to determine equal cost paths to the same destination prefix. The multiple paths can be used for load sharing of traffic and allows faster convergence to other active paths in case of network failure. This section describes the procedures used to configure ECMP on the switch using the Java Device Manager.

Note: ECMP is only supported on the Nortel Ethernet Routing Switch 5520 and 5530. ECMP will work in a mixed stack but will not run on any Nortel Ethernet Routing Switch 5510 units in the stack.
