Chapter 44 Configuring HSRP
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 [g
roup-number] track type number [interface-priority] interface configuration
command to remove the tracking.
Step 3
standby [group-number] priority
priority [preempt [delay delay]]
Set a priority value used in choosing the active router. The range is 1 to 255;
the default priority is 100. The highest number represents the highest priority.
• (Optional) group-number—The group number to which the command
applies.
• (Optional) preempt—Select so that when the local router has a higher
priority than the active router, it assumes control as the active router.
• (Optional) delay—Set to cause the local router to postpone taking over the
active role for the shown number of seconds. 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.
Step 4
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.
Step 5
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.
