User Guidelines
Different distance values can be configured for routes learned from external
peers, routes learned from internal peers, and BGP routes locally originated. A
route with a lower preference value is preferred to a route with a higher
preference value to the same destination. Routes with a preference of 255
may not be selected as best routes and used for forwarding.
The change to the default BGP distances does not affect existing routes. To
apply a distance change to existing routes, you must force the routes to be
deleted from the RIB and relearned, either by resetting the peers from which
the routes are learned or by disabling and re-enabling BGP.
