Purpose
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.
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

Configure an interface to track other interfaces so that if one of the other

(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
