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 12 0 ( high er t ha n th e default value),
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
Step5 standby [group-number] [priority
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.
•(Optional) group-number—The group number to which the command
applies.
•(Optional) priority—Enter to set or change the group priority. The range
is 1 to 255; the default is 100.
•(Optional) delay—Set to cause the local router to postpone taking over the
active role for the number of seconds shown. The range is 0 to 3600
(1 hour); the default is 0 (no delay before taking over).
Use the no form of the command to restore the default values.
Step6 standby [group-number] track
type number [interface-priority]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.
•(Optional) group-number—The group number to which the command
applies.
•type—Enter the interface type (combined with interface number) that is
tracked.
•number—Enter the interface number (combined with interface type) that is
tracked.
•(Optional) interface-priority—Enter the amount by which the hot standby
priority for the router is decremented or incremented when the interface
goes down or comes back up. The default value is 10.
Step7 end Return to privileged EXEC mode.
Step8 show running-config Verify the configuration of the standby groups.
Step9 copy running-config
