Brett,
In the scenario described, the FW would not know that the router
had died. This is a problem that HSRP is intended to solve. You
would run HSRP on the 2 external routers and have a single default
route to the HSRP IP address. If the primary router fails, the
secondary router will as
Brett,
I believe HSRP is what you are looking for. In addition, you can have the
_primary_ router monitor the external (to the big I) interface and cut-over
to the _standby_ router if that (external) interface dies.
