The BGP process selects a single autonomous system path to use and to
pass along to other BGP-speaking routers. The algorithm for path selection is as follows:
• If the next hop is inaccessible, do not consider it.
• Consider larger BGP administrative weights first.
• If the routers have the same weight, consider the route with higher local preference.
• If the routes have the same local preference, prefer the route that the
specified router originated.
• If no route was originated, prefer the shorter AS path.
• If the AS paths are of the same length, prefer external paths over
