Why would you do this? If you have a full routing table, you don't need a default route. If you don't have full routing tables, or want/ need a default route - point it to your two major "up-streams". On routers with only a single connection, just use a static default route on that box, and don't bother learning it from your neighbours. Or have I misunderstood something? _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
