Hello Carl,

the idea here is to test ip reachability of the next hop of the default static route.

the rtr object number 114 is then used to change HSRP priority

Hope to help

When your default routes next hop reachability disappears, the priority of HSRP group 114 will be decremented by 50, the default value is 100 so will become 50 in this situation. If your other HSRP peer is greater than 50, he will become he active HSRP neighbor.

This will check for the existance of the route in the routing table.  If the default route of the device is removed (probably learning it dynamically) it will invoke  HRSP or more specifially decrement the priority by 50.

I just used it today for the first time today.  Very nice feature.
