Valid object IDs are from 1 to 65535.
2. (Optional) Congure the time delay used before communicating a change in the status of a tracked interface.
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 conguration and the tracked object’s status.

Track an IPv4/IPv6 Route
You can create an object that tracks the reachability or metric of an IPv4 or IPv6 route.
You specify the route to be tracked by its address and prex-length values. Optionally, for an IPv4 route, you can enter a VRF
instance name if the route is part of a VPN routing and forwarding (VRF) table. The next-hop address is not part of the denition of
a tracked IPv4/IPv6 route.
In order for an route’s reachability or metric to be tracked, the route must appear as an entry in the routing table. A tracked route is
considered to match an entry in the routing table only if the exact IPv4 or IPv6 address and prex length match an entry in the table.
For example, when congured as a tracked route, 10.0.0.0/24 does not match the routing table entry 10.0.0.0/8. Similarly, for an IPv6
address, 3333:100:200:300:400::/80 does not match routing table entry 3333:100:200:300::/64. If no route-table entry has the
exact IPv4/IPv6 address and prex length, the tracked route is considered to be DOWN.
In addition to the entry of a route in the routing table, you can congure the UP/DOWN state of a tracked route to be determined in
the following ways:
