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 from 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 of 0-255, 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 of 1-1000, where the default is 10.
● For OSPF, you can set the resolution in the range of 1-1592, where the default is 1.
● You cannot configure the resolution value used to map static routes. By default, Dell Networking OS
assigns a metric of 0 to static routes.
● You cannot configure the resolution value used to map RIP routes. 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.
