Chapter 40 Configuring HSRP and Enhanced Object Tracking

Configuring Enhanced Object Tracking

	Command	Purpose
Step 5
	standby [group-number]ip	Create (or enable) the HSRP group by using its number and virtual IP
	[ip-address [secondary]]	address.
		• (Optional) group-number—The group number on the interface for
		which HSRP is being enabled. The range is 0 to 255; the default is 0. If
		there is only one HSRP group, you do not need to enter a group number.
		• (Optional on all but one interface) ip-address—The virtual IP address of
		the hot standby router interface. You must enter the virtual IP address for
		at least one of the interfaces; it can be learned on the other interfaces.
		• (Optional) secondary—The IP address is a secondary hot standby router
		interface. If this keyword is omitted, the configured address is the
		primary IP address.
Step 6
	standby [group-number]track	Configure HSRP to track an object and change the hot standby priority based
	object-number [decrement	on the state of the object.
	[priority-decrement]]	• (Optional) group-number—The group number to which the tracking
		applies.
		• object-number—Number representing the object to be tracked. The
		range is from 1 to 500; the default is 1.
		• (Optional) decrement priority-decrement—Amount by which the hot
		standby priority for the router is decremented (or incremented) when the
		tracked object goes down (or comes back up). The range is from 1 to
		255; the default is 10.
Step 7
	end	Return to privileged EXEC mode.
Step 8
	show standby	Verify the standby router IP address and tracking states.
Step 9
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

Configuring Other Tracking Characteristics

You can also use the enhanced object tracking for tracking other characteristics.

•You can track the reachability of an IP route by using the track ip route reachability global configuration command.

•You can use the track ip route metric threshold global configuration command to determine if a route is above or below threshold.

•You can use the track resolution global configuration command to change the metric resolution default values for routing protocols.

•You can use the track timer tracking configuration command to configure the tracking process to periodically poll tracked objects.

Use the show track privileged EXEC command to verify enhanced object tracking configuration.
