Yes, you are correct, there is no such functionality. > - Assuming it can't, where would be the right place to implement this? > Is my guess about using an export filter a reasonable one?

It is executed only when the route is propagated through it (and not later) and it should return the same value unless the route changed. IMHO best way to implement this would be in the static protocol as a modifier for a static route. The protocol could periodically check conditions for originating static routes and acts accordingly. -- 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."
