ECMP with OSPFv3

The ECMP feature supports and complements OSPFv3 protocol.

With Equal Cost Multipath (ECMP), 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

Note

To add OSPFv3 equal cost paths in the routing table, you must first enable IPv6 ECMP feature globally.

For scaling information on the ECMP paths supported per destination prefix, see Release Notes for VOSS.
