Tracking Route Reachability

Use the following commands to configure object tracking on the reachability of an IPv4 or IPv6 route.

1. Configure object tracking on the reachability of an IPv4 or IPv6 route.
   CONFIGURATION mode
   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 500.
   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.
2. (Optional) Configure the time delay used before communicating a change in the status of a tracked route.
   OBJECT TRACKING mode
   delay {[up seconds] [down seconds]}
   Valid delay times are from 0 to 180 seconds.
   The default is 0.
3. (Optional) Identify the tracked object with a text description.
   OBJECT TRACKING mode
   description text
   The text string can be up to 80 characters.
4. (Optional) Display the tracking configuration and the tracked object’s status.
   EXEC Privilege mode
   show track object-id
