Advertise Time
Set the interval at which the master sends VRRP advertisements.
Excessive traffic or different timer setting on routers can cause the Backup timer to
time out abnormally and trigger a change of the state. To solve this problem, you
can prolong the time interval to send VRRP packets.
IMPORTANT:
Routers in the same VRRP group must use the same setting of advertisement interval.
Track
Object
Object
Configure the track object function—Add the Track object to be monitored and
the processing method:
• Object—Specify the serial number of the Track object to be monitored. You
can specify an uncreated object.
• Reduced Priority—If the status of the monitored Track object changes to
negative, the priority of the router decreases by a specified value.
• Switchover—If the status of the monitored Track object changes to negative,
the router immediately switches to the master.
IMPORTANT:
• This configuration is effective only when the router is not the IP address owner.
• When the status of the monitored Track object turns from negative to positive,
the corresponding router restores its priority automatically.
• In the list box of added Track object, the Priority/Switchover column displays
a value or the letter S, where the value represents the decreased value of the
router priority, and S represents the switchover mode.

IMPORTANT:
• This configuration is effective only when the router is not the IP address owner.
• When the status of the tracked interface turns from down or removed to up, the
corresponding router restores its priority automatically.
