Chapter40 Configuring HSRP and Enhanced Object Tracking
Configuring Enhanced Object Tracking
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.

Step 5
standby [group-number] ip
[ip-address [secondary]]
Create (or enable) the HSRP group by using its number and virtual IP
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
object-number [decrement
[priority-decrement]]
Configure HSRP to track an object and change the hot standby priority based
on the state of the object.
• (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

Step 9
