Hi, you are right, but note that 'if bgp_path = 64515 then reject;' does not check whether it is exactly only 64515 in the path, it is just type error (and it is probably reported, but to logs, not to birdc shell). But i wonder why it is shown in such case, as any error during filter execution is generally handled as reject. > I suggest to use something like: > > if bgp_path ~ [= * 64515 * =] then reject; This should work, but simpler way is this: if 64515 ~ bgp_path then reject; > > This should reject any bgp_path contains AS 64515. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santi...@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
