Object Tracking
Configure the protocol-specific resolution value used to scale an IPv6 route metric.
track resolution ipv6 route {isis resolution-value | ospf resolution-value}
To return to the default setting, enter no track object-id.
object-id
Enter the ID number of the tracked object. Range: 1 to 65535.
isis
Enter the resolution used to convert the metric in the routing table for ISIS routes to a
scaled metric.
resolution-value
ospf
Enter the resolution used to convert the metric in the routing table for OSPF routes to
a scaled metric.
resolution-value
None
CONFIGURATION
Version 8.4.1.0
Introduced
threshold metric
Configure the metric threshold used to determine the UP and/or DOWN state of a tracked
route.
track ipv6 route
Configure object tracking on the threshold of an IPv6 route metric.
metric threshold
Use this command to configure the protocol-specific resolution value that converts the actual metric of
an IPv6 route in the routing table to a scaled metric in the range 0 to 255.
The UP/DOWN state of a tracked IPv6 route is determined by the user-configurable threshold
(threshold metric
command) for a route's metric in the routing table. To provide a common tracking
interface for different clients, route metrics are scaled in the range 0 to 255, where 0 is connected and
255 is inaccessible.
The protocol-specific resolution value calculates the scaled metric by dividing a route's cost by the
resolution value set for the route protocol:
•
For ISIS, you can set the resolution in the range 1 to 1000, where the default is 10.
•
For OSPF, you can set the resolution in the range 1 to 1592, where the default is 1.
•
The resolution value used to map static routes is not configurable. By default, FTOS assigns a
metric of 0 to static routes.
•
The resolution value used to map RIP routes is not configurable. The RIP hop-count is
automatically multiplied by 16 to scale it. For example, a RIP metric of 16 (unreachable) scales to
256, which considers the route to be DOWN.
