duration.
This is used to avoid failing

transient failures.
The value of duration is the
length of time that the
administrator expects will be
long enough that the database
gathered in the time is too
important to be lost. This will
obviously vary from instance
to instance.
The recommended value of
value in conjunction to the
values for priority in step 4 is
20.
Step 8 no shutdown Administratively enables the
VRRP instance. N/A.
