[ savvis folks asking which versions have the "bug"] we just found that 11.1.7ca1 contains the "bug" but we haven't gotten an exact description of what the bug is. in general terms, it's only been described as: "a bgp router can be slow in withdrawing prefixes even though they've been withdrawn from the originator(s)." doesn't say much, does it? :) they're working on a fix. i'm afraid i dont' know which other versions have the same problem though. we only asked about a particular version we run. -brett
