problems can be solved through prolonging the adver-interval and setting delay time. If
you configure the preemption delay for a backup switch, the switch preempts the
master after the period specified by the preemption delay if it does not receive a VRRP
packet from the master for the period specified by the master-down-interval argument.
V. The VLAN interfaces to be tracked for a backup group
The VLAN interface tracking function expands the backup group function. With this
function enabled, the backup group function is provided not only when the interface
where the backup group resides fails, but also when other interfaces are unavailable.
By executing the related command you can track an interface.
When a tracked VLAN interface goes down, the priority of the switch owning the
interface will reduce automatically by a specified value (the value-reduced argument). If
the switches with their priorities higher than that of the current master switch exist in the
backup group, a new master switch will be then determined.
VI. Introduction to the Port Tracking Function
VRRP backup group port tracking function can track the link state of the physical port,
and decrease the priority of the switch when the physical port fails.
When the master's uplink physical port fails, the priority of the master switch is
decreased by a set value. This in turn triggers the new master to be determined in the
backup group.
VII. Auto Detect Implementation in VRRP
You can control the priority of the VRRP backup group according to the auto detect
result to enable automatic switch between the master switch and the standby switch as
follows:
Decrease the priority of a backup group when the result of the detecting group is
unreachable.
Restore the priority of a backup group when the result of the detecting group is
reachable.
Refer to Auto Detect module of this manual for information about auto detect.
