Authentication
Set the authentication mode and plain text authentication key of the VRRP group.
• Null—no authentication and no authentication key.
• Simple—simple text authentication. In this case, you need to configure a plain
text authentication key.
• MD5—MD5 authentication. In this case, you need to configure a plain text
authentication key.
TIP:
You can configure different authentication modes and authentication keys for the
VRRP groups on an interface. However, the members of the same VRRP group must
use the same authentication mode and authentication key.
Key
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.
TIP:
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.
TIP:
• When the router is the IP address owner, you cannot perform the configuration.
• 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.

Interface
Interface
Configure the track interface function: add the specified interface to be monitored
and the processing method.
• Interface—name of the interface to be tracked.
• Reduced Priority—If the status of the monitored interface turns from up to down,
the priority of the router decreases by a specified value.
TIP:
• When the router is the IP address owner, you cannot perform the configuration.
• When the status of the tracked interface turns from down or removed to up, the
corresponding router restores its priority automatically.
• The specified interface can be a Layer 3 Ethernet interface or a VLAN interface.
