The route comparison algorithm can be very simple. get a new route in a BGP update if the route passes policy filter criteria, compare to the current best route for the AS using all criteria - local-pref, med, igp, advertiser IP address if the best route for the AS changed, compare it to the overall best route using all the criteria except MED - local-pref, igp, advertiser IP address if the new route is better you have a new best route. Simple to explain. Simple to implement. No loop. Curtis
