Here is the scenario:
Cisco Router is behind a Cable modem. This same cisco router has another ethernet connection to another Cisco router. I want the default route to go out the cable modem. But in the event the connection on the far side of the cable is down I want the default route to over to the other cisco router.
I know that a floating static will not work because the interface between the Cisco router and the cable modem hasn't gone down. I know that policy routing to verify the next hop will not work because it isn't another Cisco device on the other of the cable modem.
Is there a way I can constantly ping another device on the back side of the cable modem to verify that it is available, if it isn't to some how change the default route in the routing table. (i.e. TCL scripting of other method). I really appreciate everyone's help.
