The points in the network your referring to, are not under your sirect control, so there's not a lot tc/ip can directly do to solve your problem. but with some clever scripting, you could attempt to detect a fault in the network, and take appropriate action. such as delete the faulty route for all the clients that were using it, and forec them onto the other route. you'll still need to be able to test the dead route from the box, such that you can activate again, once its working. i hope i understood the problem correctly, and havent gone off on one. -vince -- PGP key: http://codex.net/pgp/pgp.asc Computers make very fast, very accurate mistakes.
