This is trivial to do only as far as your $s carry. Aggregate draws the traffic, then NO_EXPORT-tagged longest-match carries the regionalized traffic. Folks do this as a 'best exit' approach between peer netwworks all the time. If you are suggesting disjoint, unconnected islands, then they should be separate ASNs for sane paths; see charter's islands, the pre-271 refleif ILEC LATA-bound islands, etc. -- RSUC / GweepNet / Spunk / FnB / Usenix / SAGE
