Configuration procedure
To associate Track with BFD:
Step
1.
Enter system view.
2.
Create a track entry,
associate it with the BFD
session, and specify the delay
time for the Track module to
notify the associated
application module when the
track entry status changes.
Associating Track with interface management
The interface management module monitors the link status or network-layer protocol status of the
interface. The interface management module functions as follows when it is associated with a track entry:
When the link or network-layer protocol status of the interface changes to up, the interface
•
management module informs the Track module of the change and the Track module sets the track
entry to Positive.
•
When the link or network-layer protocol status of the interface changes to down, the interface
management module informs the Track module of the change and the Track module sets the track
entry to Negative.
To associate Track with interface management:
Step
1.
Enter system view.
2.

Create a track entry, associate it with the interface
management module to monitor the link status of
an interface, and specify the delay time for the
Track module to notify the associated application
module when the track entry status changes:
track track-entry-number interface interface-type
interface-number [ delay { negative negative-time
| positive positive-time } * ]
•
Create a track entry, associate it with the interface
management module to monitor the Layer 3
protocol status of an interface, and specify the
delay time for the Track module to notify the
associated application module when the track
entry status changes:
track track-entry-number interface interface-type
interface-number protocol { ipv4 | ipv6 } [ delay
{ negative negative-time | positive positive-time }
* ]
