Usage Information
Use this command to configure the protocol-specific resolution value that converts the
actual metric of an IPv4 route in the routing table to a scaled metric in the range 0 to
255.
The UP/DOWN state of a tracked IPv4 route is determined by a user-configurable
threshold (the threshold metric command) for the 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, Dell
Networking OS 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.
