Re: Modem dial-up when route goes down (failover)

[Jonathan Bartlett <johnnyb eskimo com>]

I would write a bash script that would ping the gateway, and if it fails 3
times in a row (check the return code of ping), ifdown the main interface
and ifup the ppp interface.  You would have to manually fail it back over,
however, so you probably want it to email you after the ifup is complete.

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!
