Version 8.4.1.0 Description Introduced. 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. Related Commands • threshold metric - configures the metric threshold used to determine the UP and/or DOWN state of a tracked route. • track ip route metric threshold - configures object tracking on the threshold of an IPv4 route metric. IPv6 Object Tracking Commands The following section describes the IPv6 object tracking commands. The following object tracking commands apply to IPv4 and IPv6: • debug track • delay • description • show running-config track • threshold metric • track interface line-protocol Object Tracking 1472
