net access failover

[mark abrams]

Hello,

I have a cable modem and and a dsl connction to my machine. I would like to 
use the cable modem as my default connection and automatically fail-over to 
the dsl connection if/when the cable modem goes down.

Can routed(8) do this ? If so how? And is there a better way ?

Any hints appreciated.

Thanks,

MArk
