It has nothing to do with available IP address space. It is purely the number of routes in the "global" BGP routing table. Doing rout filtering a la Sprint is one way to enforce better aggregation and cut down on route table size. Also, in general, the longer the prefix, the more a route tends to flap. Route filtering is one way to help cust down on the number of BGP updates. > >Are any other ISPs doing this filtering?
