Have a look at the gateway selecor; this will do exactly what you want
(switch to a "backup" default gateway incase the first one is down.

Subject: [gb-users] How can I dynamically alter default routes?
Hello,
I've been racking my brain trying to come up with a way configure our two
location network to provide redundant access to the internet. I can solve
everything except what to do about getting around default routes.
We have two locations connected by a T1. Each location has its own internet
connection through a GB-1000.
Location A
ISP router: A.0.1.1
GB-1000
external interface:: A.0.1.2
protected interface: A.0.2.1
gateway selector routes: A.0.1.1 A.0.2.2
T1-router
LAN: A.0.2.2
Wan: AB.0.0.1
default route: A.0.2.1
Location B:
T1-router
Wan: AB.0.0.2
LAN:: B.0.2.2
default route: AB.0.0.1
GB-1000
protected interface: B.0.2.1
external interface:: B.0.1.2
gateway selector: B.0.1.1 B.0.2.2
ISP router B.0.1.1
I have successfully tested one side the above configuration by disconnecting
the cable between the ISP router and the GB-1000 at location B. Internet
traffic is routed over the T1 to the GB-1000 at location A and out the
internet and back again. This works because the default routes of the T1
routers push public addresses in that direction. My question is, is there a
way to get it to work in the opposite direction without manually changing
the default routes in the T1 routers?
Thanks in advance for any and all responses.
Gene
