nexthop weight (OSPFv3 view)

Function

The nexthop weight command sets the priority for equal-cost routes.

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

By default, the value of weight-value is 255, and equal-cost routes load balance traffic.

Format

nexthop neighbor-id { interface-name | interface-type interface-number } weight value

undo nexthop neighbor-id { interface-name | interface-type interface-number }

Parameters

Parameter	Description	Value
neighbor-id	Specifies the router ID of a neighbor.	The value is in dotted decimal notation.
interface-type	Specifies the type of an interface.	-
interface-number	Specifies the number of an interface.	-
weight value	Specifies a priority for the next hop. The smaller the value, the higher the priority.	The value is an integer ranging from 1 to 254.

Usage Guidelines

Usage Scenario

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

If the number of equal-cost routes on a network is greater than the value set using the maximum load-balancing command and specified equal-cost routes need to be used for load balancing, run the nexthop command to a high priority for these routes.

Example

# Set the priority for OSPFv3 equal-cost routes.
