Description: The cHsrpGrpPriority helps to select the active and the standby routers. The router with the highest priority is selected as the active router. In the priority range of 0 to 255, 0 is the lowest priority and 255 is the highest priority.

If two (or more) routers in a group have the same priority, the one with the highest ip address of the interface is the active router. When the active router fails to send a Hello message within a configurable period of time, the standby router with the highest priority becomes the active router.

A router with highest priority will only attempt to overthrow a lower priority active router if it is configured to preempt. But, if there is more than one router which is not active, the highest priority non-active router becomes the standby router.
