Re: Addr: Re: BGP-4 - revised I-D

   The algorithm is very simple.

     get a new route in a BGP update

     if the [r]oute passes policy filter criteria, compare to the current
     best route for the AS using all criteria - local-pref, med, igp,
     advertiser IP address

Ok, so what do I do after comparing?  I _assume_ you mean that if the new
route is NOT better than the current best route from that neighboring AS,
then no further testing need be done.  Otherwise, the new route is the best
route via the neighboring AS.

     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.

Agreed.  Now there are two problems: a) wordsmithing b) explaining the
functionality rather than the implementation.

I think we are in violent agreement on semantics.
