nexthop (OSPFv3)

Function

The nexthop command sets the preference for equal-cost routes.

The undo nexthop command cancels the preference of equal-cost routes.

By default, the preference is not set for equal-cost routes. That is, equal-cost routes forward packets at the same time for load balancing.

Usage Guidelines

After OSPFv3 calculates equal-cost routes, you can run the nexthop command to select the route with the highest preference from the equal-cost routes as the next hop. OSPFv3 selects a next hop from these equal-cost routes according to the weight. The smaller the weight is, the higher the route preference is.

Example

# Set the preference for equal-cost routes in OSPFv3.
