There is a big difference if you are trying to failover for incoming 
traffic with a range of IP addresses or if you are just looking to have 
outgoing traffic just continue working in case of a failure of your 
primary link.

If you are trying to provide outgoing Internet connectivity only, 
<http://lartc.org/lartc.html> should provide you instructions for what you 
are trying to accomplish.
