Modem dial-up when route goes down (failover)

[Stephen Corey <palmos3 yahoo com>]

I want to setup my RH 7.3 box so if my main route to the Internet goes down, the system will dial the Internet with a modem and use that as the primary route. How would I do that? I've heard someone say they've done that with using OSPF, but I don't have all the details. I basically need it to dial when I'm unable to contact my default gateway (which would usually mean the WAN link is down). Thanks!
