8.4.1.0 Introduced.
Usage
Information
Use this command to create an object that tracks the line-protocol state of a Layer 2 interface by
monitoring its operational status (UP or DOWN).
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.

Commands
● show track – display information about tracked objects, including configuration, current state, and
clients which track the object.
● track interface ip routing – configure object tracking on the routing status of an IPv4 Layer 3
interface.
track ip route metric threshold
Configure 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/
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 forwarding (VRF)
instance to specify the virtual routing table to which the tracked route belongs.

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 prefix length match a table entry. For example, when configured as a tracked route, 10.0.0.0/24 does
