Chapter 40 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.
configuration command.
•
You can use the track ip route metric threshold global configuration command to determine if a
route is above or below threshold.
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.
default values for routing protocols.
•
You can use the track timer tracking configuration command to configure the tracking process to
periodically poll tracked objects.
periodically poll tracked objects.
Use the show track privileged EXEC command to verify enhanced object tracking configuration.
