threshold metric
Congure the metric threshold used to determine the UP and/or DOWN state of a tracked IPv4 or IPv6 route.
Syntax
threshold metric {up number | down number}
To return to the default setting, use the no threshold metric {up number | down number}
command.
Parameters
up number Enter a number for the UP threshold to be applied to the scaled metric of an IPv4
or IPv6 route. 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.
down number Enter a number for the DOWN threshold to be applied to the scaled metric of an
IPv4 or IPv6 route. The default DOWN threshold is255. The routing state is DOWN
if the scaled route metric is greater than or equal to the DOWN threshold.
Defaults none

Usage Information
Use this command to congure the UP and/or DOWN threshold for the scaled metric of a tracked IPv4 or
IPv6 route.
Determine the UP/DOWN state of a tracked route by the threshold for the current value of the route metric
in the routing table. To provide a common tracking interface for dierent clients, route metrics are scaled in
the range 0 to 255, where 0 is connected and 255 is inaccessible. The scaled metric value communicated to
a client always considers a lower value to have priority over a higher value.
The resulting scaled value is compared against the congured threshold values to determine the state of a
tracked route as follows:
• If the scaled metric for a route entry is less than or equal to the UP threshold, the state of a route is UP.
