First off, I apologize for having left the mail client on 'send in html
So, in a nut shell, since a) the isp's are not going to be peering with
me and b) the gateway devices themselves aren't supported to give me
even their status, I need to implement some route checking scripts to
add or remove the bad default gateway if it happens to go down? Is my
line of thinking correct, or am I missing some information about how
osfp/rip enabled programs work, or is there another tool available to do

that appears to have a 2.2.16 kernel with equal cost multi path and
advanced routing options compiled into it. The box does not have rip,
gated, or any other route checking program running on it. The two links
to the internet go out through different ethernet cards, hubs, then
gateway devices. The gateway devices as far as I am concerned are dumb
devices that dont know if they are working or not.
