threshold metric {[up number ] [down number ]}
The default UP threshold is 254 . The routing state is UP if the scaled route metric is less than or equal to the UP threshold.
The defult DOWN threshold is 255 . The routing state is DOWN if the scaled route metric is greater than or equal to the DOWN
threshold.

Example of IPv4 and IPv6 Tracking Metric Thresholds
The following example configures object tracking on the metric threshold of an IPv4 route:
Dell(conf)#track 6 ip route 2.1.1.0/24 metric threshold
Dell(conf-track-6)#delay down 20
Dell(conf-track-6)#delay up 20
Dell(conf-track-6)#description track ip route metric
Dell(conf-track-6)#threshold metric down 40
Dell(conf-track-6)#threshold metric up 40
Dell(conf-track-6)#exit
Dell(conf)#track 10 ip route 3.1.1.0/24 metric threshold
vrf vrf1
Example of IPv4 and IPv6 Tracking Metric Thresholds
The following example configures object tracking on the metric threshold of an IPv6 route:
Dell(conf)#track 8 ipv6 route 2::/64 metric threshold
Dell(conf-track-8)#threshold metric up 30
Dell(conf-track-8)#threshold metric down 40
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 ]
