Configuring the default local preference

The local preference is used to determine the best route for traffic leaving the local AS. When a BGP
router obtains from several IBGP peers multiple routes to the same destination, but with different next
hops, it considers the route with the highest local preference as the best route.
This task allows you to specify the default local preference for routes sent to IBGP peers.
