The problem is if they aggregate and advertise only a /19 instead of individual /24s In this case you could:
- Ask the pulverized ISP to withdraw the aggregate in favor of the specific /24s - Ask your second ISP to advertise your specific /24 in that city
Better yet, advertise your own /19 aggregate, mark your /24's with communities that mean to your provider that they shouldn't be propagated outside of their network and their customers (if they can't do this, fire them) to be a good neighbor by not polluting the global routing table with unnecessary routes. Then when the asteroid hits, just pull down the /19 advertisement (or if you're lucky, they are so destroyed they won't get the announcement out to the world anymore anyway). -- Brandon Ross 404-522-5400 EVP Engineering, NetRail http://www.netrail.net AIM: BrandonNR ICQ: 2269442 Read RFC 2644!
