vrf-name]
To return to the default setting, use the no track object-id command.
Parameters
object-id Enter the ID number of the tracked object. The range is 1 to 500.
ip-address/
prefix-len
Enter an IPv4 address in dotted decimal format. The valid IPv4
prefix lengths are from /0 to /32.
vrf vrf-name (Optional) E-Series only: You can configure a VPN routing and

Usage Information
Use this command to create an object that tracks the reachability of an IPv4 route. In
order for a route’s reachability to be tracked, the route must appear as an entry in the
routing table.
A tracked IPv4 route is considered to match an entry in the routing table only if the
exact IPv4 address and prefix length match a table entry. For example, when configured
as a tracked route, 10.0.0.0/24 does not match the routing table entry 10.0.0.0/8. If no
route-table entry has the exact IPv4 address and prefix length, the status of the tracked
route is considered to be DOWN.
