For an IPv6 interface, a routing object only tracks the UP/DOWN status of the specied IPv6 interface (the track interface ipv6-
routing command).
• The status of an IPv6 interface is UP only if the Layer 2 status of the interface is UP and the interface has a valid IPv6 address.
• The Layer 3 status of an IPv6 interface goes DOWN when its Layer 2 status goes down (for a Layer 3 VLAN, all VLAN ports must be
down) or the IPv6 address is removed from the routing table.
To remove object tracking on a Layer 3 IPv4/IPv6 interface, use the no track object-id command.
To congure object tracking on the routing status of a Layer 3 interface, use the following commands.
1 Congure object tracking on the routing status of an IPv4 or IPv6 interface.
CONFIGURATION mode
track object-id interface interface {ip routing | ipv6 routing}
Valid object IDs are from 1 to 500.
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.
EXEC Privilege mode
show track object-id

The following is an example of conguring object tracking for an IPv4 interface:
