Disabled; group defaults to 0

Description

This command instructs the interface to become the active HSRP interface if no other HSRP router within the given group has a higher priority. In other words, if this interface becomes active and has the standby preempt command, it interrupts any other HSRP interface and becomes the active HSRP interface. The default group number is 0.
