When the link-level status goes down, the tracked object status is considered to be DOWN; if the link-level status
is up, the tracked object status is considered to be UP.
Related Commands
• show track – display information about tracked objects, including conguration, current state, and clients which
track the object.
• track interface ip routing – congure object tracking on the routing status of an IPv4 Layer 3 interface.
track ip route metric threshold
Congure 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, 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/ prex-
len
Enter an IPv4 address in dotted decimal format. The valid IPv4 prex lengths are from /0
to /32.
vrf vrf-name (Optional) E-Series only: You can congure a VPN routing and forwarding (VRF) instance
to specify the virtual routing table to which the tracked route belongs.
Defaults None

Usage Information
Use this command to create an object that tracks the UP and/or DOWN threshold of an IPv4 route metric. In order
for a route’s metric 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 prex
length match a table entry. 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. If no route-table entry has the exact IPv4 address and prex length, the status of the
tracked route is considered to be DOWN.
When you congure the threshold of an IPv4 route metric as a tracked object, the UP/DOWN state of the tracked
route is also determined by the current metric for the route in the routing table.
