Configuring Collaboration Between The Track Module And The Application Modules - HP 4800G Series Configuration Manual

When you configure a Track object, the specified NQA test group and Reaction entry can be
nonexistent. In this case, the status of the configured Track object is Invalid.
Configuring Track-BFD Collaboration
Through the following configuration, you can establish the collaboration between the Track module and
BFD, which probes the link status and informs the Track module of the probe result.
Follow these steps to configure Track-BFD collaboration:
To do...
Enter system view
Create a Track object and
associate it with the BFD

Configuring Track-VRRP Collaboration
Through the Track-VRRP collaboration, you can:
Monitor the upper link. If there is a fault on the upper link of the master of a VRRP group, hosts in
the LAN cannot access the external network through the master. In this case, the status of the
monitored Track object changes to Negative, and the priority of the master thus decreases by a
specified value, allowing a higher priority router in the VRRP group to become the master to
maintain proper communication between the hosts in the LAN and the external network.
Monitor the master on a backup. If there is a fault on the master, the backup working in the
switchover mode will switch to the master immediately to maintain normal communication.
Configuration prerequisites
Before configuring VRRP to monitor a Track object, you need to create a VRRP group on an interface
and configure the virtual IP address of the VRRP group.
