configure bgp neighbor weight

configure bgp neighbor [remoteaddr | all] weight weight

Description

Assigns a locally-used weight to a neighbor connection for the route selection algorithm.

Syntax Description

remoteaddr Specifies the IPv4 or IPv6 address of a BGP neighbor.
all Specifies all IPv4 and IPv6 neighbors.
weight Specifies a BGP neighbor weight.

Default

By default, the weight is 1.

Usage Guidelines

All routes learned from this peer are assigned the same weight. The route with the highest weight is more preferable when multiple routes are available to the same network. The range is 0 to 65,535.

BGP selects routes based on the following precedence (from highest to lowest):

  • higher weight

  • higher local preference

  • shortest length (shortest AS path)

  • lowest origin code

  • lowest MED

  • route from external peer

  • lowest cost to Next Hop

  • lowest routerID

This command applies to the current VR or VRF context.

Example

The following command assigns a locally used weight of 10 to a neighbor connection:

configure bgp neighbor 192.168.1.5 weight 10
