Default Configuration
No type of object tracking is configured.
Tracking Interface Line-Protocol or IP Routing State
You can track either the interface line protocol state or the interface IP routing state. When you track the
IP routing state, these three conditions are required for the object to be up:
IP routing state, these three conditions are required for the object to be up:
•
IP routing must be enabled and active on the interface.
•
The interface line-protocol state must be up.
•
The interface IP address must be known.
If all three of these conditions are not met, the IP routing state is down.
Beginning in privileged EXEC mode, follow these steps to track the line-protocol state or IP routing state

and enter tracking configuration mode.
•
The object-number identifies the tracked object and can be from 1 to 500.
•
The interface interface-id is the interface being tracked.
Step 3
