Configure this with the same value
as the VLAN ID for easy
administration.
Recommended to
Advertisement Interval
The interval between successive
VRRP advertisements sent by the
current master.
Recommended to leave as default
(1000ms = 1s).

Pre-emption
A WFS709TP can take over the
role of master if it detects a lower
priority WFS709TP currently
acting as master.
For this topology, it is
recommended not to select this
option.
Priority Priority level of the VRRP instance
for the WFS709TP. This value is
used in the election mechanism for
the master.
It is recommended to leave this as
the default for this topology
(default = 100).
Tracking Configures a tracking mechanism
that adds a specified value to the
priority after a WFS709TP has
been the master for the VRRP
instance. This mechanism is used
to avoid failing over to a backup
Master for transient failures.
Tracking can be based on one of
the following:
• Master Up Time: how long the
switch has been the master.
• VRRP Master State Priority: the
master state of another VRRP.
Recommended to leave this as the
default for this topology (default =
100).
