Displaying Tracked Objects
To display the currently configured objects used to track Layer 2 and Layer 3 interfaces, and IPv4 and
IPv6 routes, use the following
show
commands.
To display the configuration and status of currently tracked Layer 2 or Layer 3 interfaces, IPv4 or IPv6
routes, or a VRF instance, use the
show track
command. You can also display the currently configured
per-protocol resolution values used to scale route metrics when tracking metric thresholds.
• Display the configuration and status of currently tracked Layer 2 or Layer 3 interfaces, IPv4 or IPv6
routes, and a VRF instance.
show track [ object-id [brief] | interface [brief] [vrf vrf-name ] | ip route
[brief] [vrf vrf-name ] | resolution | vrf vrf-name [brief] | brief]
• Use the
show running-config track
command to display the tracking configuration of a
specified object or all objects that are currently configured on the router.
show running-config track [ object-id ]
