Tracking Route Reachability To configure object tracking on the reachability of an IPv4 or IPv6 route, use the following commands. To remove object tracking, enter the no track object-id command. Step 1 2 3 4 Task Command Syntax Command Mode Configure object tracking on the reachability of an IPv4 or IPv6 route. (Optional) Configure the time delay used before communicating a change in the status of a tracked route. track object-id {ip route ip-address/prefix-len | ipv6 route ipv6-address/prefix-len} reachability [vrf vrf-name] Valid object IDs are from 1 to 65535. Enter an IPv4 address in dotted decimal format; valid IPv4 prefix lengths are from /0 to /32. Enter an IPv6 address in X:X:X:X::X format; valid IPv6 prefix lengths are from /0 to /128. (Optional) E-Series only: For an IPv4 route, you can enter a VRF name to specify the virtual routing table to which the tracked route belongs. delay {[up seconds] [down seconds]} Valid delay times are from 0 to 180 seconds. Default: 0. CONFIGURATION OBJECT TRACKING (Optional) Identify the tracked object with a text description. (Optional) Display the tracking configuration and the tracked object's status. description text The text string can be up to 80 characters. show track object-id OBJECT TRACKING EXEC Privilege Command Example: track ip route reachability FTOS(conf)#track 104 ip route 10.0.0.0/8 reachability FTOS(conf-track-104)#delay up 20 down 10 FTOS(conf-track-104)#end FTOS#show track 104 Track 104 IP route 10.0.0.0/8 reachability Reachability is Down (route not in route table) 2 changes, last change 00:02:49 Tracked by: FTOS#configure FTOS(conf)#track 4 ip route 3.1.1.0/24 reachability vrf vrf1 Object Tracking | 651
