Usage Guidelines

Usage Scenario

Local_Pref is used to determine the optimal route for the traffic that leaves an AS. If BGP receives from different IBGP peers multiple routes to the same destination address but with different next hops, it selects the route with the largest Local_Pref value.

Configuration Impact

If the default local-preference command is run more than once, the latest configuration overrides the previous one.

Precautions

The Local_Pref is valid among IBGP peers and is not advertised to other ASs.

Example

# Set the Local_Pref for BGP routes to 200.
