Usage Scenario
The Local_Pref attribute is used to determine an optimal route for traffic before traffic leaves an AS. When the switch that runs BGP has multiple routes to the same destination, the switch selects the route with the highest local preference as the optimal route.
Precautions
If the switch is already configured with a default local preference for BGP routes, the configuration of a new default local preference will override the previous configuration.
The local preference is exchanged only between IBGP peers and is not advertised to other ASs.
