configure bgp local-preference

configure bgp local-preference number

Description

Changes the default local preference attribute.

Syntax Description

number Specifies a value used to advertise this router‘s degree of preference to other routers within the AS. Range is 0 to 2147483647.

Default

100.

Usage Guidelines

BGP must be disabled before the local preference attribute can be changed.

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

Local preference is used to determine a preferred exit point from an AS. Local preferences are exchanged throughout the AS. A change in the local-preference can result in a change in routing and forwarding of traffic leaving the AS.

Example

The following command changes the default local preference attribute to 500:

configure bgp local-preference 500
