CLI Guide

• 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.
You configure the UP and DOWN thresholds for each tracked route by using the
threshold metric 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.
