• If the scaled metric for a route entry is less than or equal to the UP threshold, the state of a route is UP. • If the scaled metric for a route is greater than or equal to the DOWN threshold or the route is not entered in the routing table, the state of a route is DOWN. You configure the UP and DOWN thresholds for each tracked route with the threshold metric command. The default UP threshold is 254; the default DOWN threshold is 255. The notification of a change in the state of a tracked object is sent when a metric value crosses a configured threshold. The tracking process uses a protocol-specific resolution value to convert the actual metric in the routing table to a scaled metric in the range 0 to 255. You can configure the resolution value used to scale route metrics for supported protocols with the track resolution ip route and track resolution ipv6 route commands. track c e s Enter Object Tracking command mode to modify the configuration of a tracked object. Syntax track object-id Parameters object-id Enter the ID number of the tracked object. Range: 1 to 65535. Defaults None Command Modes CONFIGURATION Command History Related Commands Version 8.4.1.0 Introduced show track Display information about tracked objects, including configuration, current state, and clients which track the object. Usage Information Use this command to enter the Object Tracking mode to edit an existing configuration of a tracked object. For example, after you enter the track object-id command, you can modify or add a delay timer (delay command) or a metric threshold (threshold metric command) for the UP or DOWN state of the tracked object. track ip route metric threshold c e s Configure object tracking on the threshold of an IPv4 route metric. Syntax track object-id ip route ip-address/prefix-len metric threshold [vrf vrf-name] To return to the default setting, enter no track object-id. Parameters object-id Enter the ID number of the tracked object. Range: 1 to 65535. Object Tracking | 993
