You should be able to accomplish this with the interface tracking option in
HSRP.

Subject: Re: HSRP [7:10428]
I think it would help if I gave you the scenario I was envisioning. I would
like to plan a network where we have 2 seperate routers connecting to our
ISP or perhaps 2 seperate ISP's. Lets assume 1 ISP, 2 routers ,each with its
own full T1 line for simplicity. If 1 router died, I'd like to keep the
internet connection alive without changing any of the clients default
gateways. I figured HSRP would be good to apply here becuase it acts as 1
virtual router. But, would that mean that 1 router would be idle at all
times not allowing me to ever get more than 1.5MB bandwidth? Or this extra
idle T1 line just the cost of redundancy in this case?
