Routing Issues DUAL ISP - Subinterface

Dear all,,,,I have an internet router connecting to two different ISP's using a layer 2 switch. ISP1 is primary and ISP 2 is in standby. I am not doing any load balancing. I am using subinterfaces for connecting to two ISP's. Is there any way to do tracking so that if ISP 1 goes down automatically it should take over to ISP 2. Currently i am using default route towards two different gateways... please let me know your thoughts...

You can use IP SLA with Track object.

Note : -  don't forget to add permanent keyword at the end of 4.2.2.2 route.
