Usage guidelines
By default, BGP does not compare MEDs for routes from the same AS. When a router learns a new route,
it compares the route with the optimal route in its BGP routing table. If the new route is more optimal, it
becomes the optimal route in the BGP routing table. In this way, route learning sequence might affect
optimal route selection.
