Configuring HSRP
Use the no standby [group-number] priority priority [preempt [delay delay]] and no standby
[group-number] [priority priority] preempt [delay delay] interface configuration commands to restore
default priority, preempt, and delay values.

Use the no standby [group-number] track type number [interface-priority] interface configuration
command to remove the tracking.

This example activates a port, sets an IP address and a priority of 120 (higher than the default value),
and waits for 300 seconds (5 minutes) before attempting to become the active router:
and waits for 300 seconds (5 minutes) before attempting to become the active router:
Switch# configure terminal
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# no switchport
Switch(config-if)# standby ip 172.20.128.3
Switch(config-if)# standby priority 120 preempt delay 300
Switch(config-if)# end
Step 4
standby [group-number] [priority
priority] preempt [delay delay]
priority] preempt [delay delay]
Configure the router to preempt, which means that when the local router has
a higher priority than the active router, it assumes control as the active router.

Configure an interface to track other interfaces so that if one of the other
interfaces goes down, the device’s Hot Standby priority is lowered.
