Half correct. Everyone in the area carries full routes for the block. Everyone outside the area can listen to only the /8 advertisement. Once their packets get within the geographical area, then the routers will know what to do with it. So, no matter how bad a swamp this block becomes (and that would be avoided if possible, but...), it doesn't impact the outside world very much (1 advertisement and more-than-normal care on filter sets, since this is a special case). -george
