Using a floating (i.e. AD >> normal, e.g. 250) static Null0-route is IMHO the best idea. Keep in mind that when the source of a BGP prefix changes from e.g. a connected net to a static Null0-route the attributes will change, and that might have an effect regarding e.g. route-flap dampening. Supressing the more specifics with e.g. "aggragate-addresse" might help here. Otherwise a Loopback interface configured just like you would the Ethernet interface should, like Tim mentioned, work out right. -- Peter _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
