Through the following configuration, you can establish the collaboration between
the Track module and the NQA, which probes the Reaction entry and informs the
Track module of the probe result.
Follow these steps to configure Track-NQA collaboration:
To do...
Enter system view
Create a Track object and
associate it with the specified
Reaction entry of the NQA
test group
c
CAUTION: 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.
You can monitor the upper link through the Track-VRRP collaboration. If there is a
fault on the upper link, hosts in the LAN cannot access the external network
through the master router. In this case, the status of the monitored Track object
changes to negative, and the priority of the router thus decreases by a specified
value, allowing a higher priority router to become the master to maintain proper
communication between the hosts in the LAN and the external network.
Configuration prerequisites
Before configuring VRRP to monitor a Track object, you need to create a standby
group on an interface and configure the virtual IP address of the standby group.
Configuration procedure
Follow these steps to configure Track-VRRP collaboration:
To do...
Enter system view
