Associating Track With Interface Management - HP 6125G Configuration Manual

The BFD functions as follows when it is associated with a track entry:
• If the BFD detects that the link fails, it informs the track entry of the link failure. The track module then
sets the track entry to the Negative state.
If the BFD detects that the link is normal, the track module sets the track entry to the Positive state.
•
For more information about BFD, see
Configuration prerequisites
Before you associate track with BFD, configure the source address of the BFD echo packets.
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.
NOTE:
When associating track with BFD, do not configure the virtual IP address of a VRRP group as the local or
remote address of a BFD session.

Associating track with interface management

The interface management module monitors the physical 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 physical 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 physical 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.
