The ECMP feature supports and complements BGP+ protocol.
The number of equal-cost-paths supported can differ by hardware platform. For more information, see Fabric Engine Release Notes.
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 and IPv6 traffic. Equal Cost Multipath is formed using routes from the same protocol.
Note
To add BGP+ equal cost paths in the routing table, you must enable the following:
