You configure the UP and DOWN thresholds for each tracked route with the
command. The default UP threshold is 254; the default DOWN threshold is 255. The notification of a
change in the state of a tracked object is sent when a metric value crosses a configured threshold.
The tracking process uses a protocol-specific resolution value to convert the actual metric in the
routing table to a scaled metric in the range 0 to 255. You can configure the resolution value used to
scale route metrics for supported protocols with the

Configure object tracking on the threshold of an IPv4 route metric.
Syntax
track object-id ip route ip-address/prefix-len metric threshold [vrf vrf-name]
To return to the default setting, enter no track object-id.
Parameters
object-id
If the scaled metric for a route entry is less than or equal to the UP threshold, the state of a route is
UP.
If the scaled metric for a route is greater than or equal to the DOWN threshold or the route is not
entered in the routing table, the state of a route is DOWN.
