Setting The Preemption Mode Of Device In The Vrrp Backup Group; Setting The Device Priority In The Vrrp Backup Group - D-Link xStack DGS-3610 Series Configuration Manual

Chapter 46 VRRP Configuration
If the current device becomes the master in the VRRP group, it will notify its VRRP status,
priority and more information by sending VRRP advertisements in the set interval. By default,
this interval is 1 second.
Note
46.3.5 Setting the Preemption Mode of
Device in the VRRP Backup Group
If the VRRP group is working in the preemption mode, a device preempts to become the
master of the VRRP group once its priority is higher than the Master priority. If the VRRP
group is not working in the preemption mode, it does not preempt to become the master of
the VRRP group even if its priority is higher than the Master priority. In case the VRRP group
is using the Ethernet interface IP address, the setting of the preemption mode does not
make sense, because that device has the highest priority and thus automatically become the
master in the VRRP group.
Command
DGS-3610(config-if)# vrrp group preempt
[delay seconds]
DGS-3610(config-if)# no vrrp group preempt
The optional parameter delay seconds defines the delay for the VRRP router prepares to
declare its Master identify, 0 seconds by default. Once the VRRP function is enabled, the
VRRP group will work in the preemption mode by default.
46.3.6 Setting the Device Priority in the
VRRP Backup Group
The VRRP stipulates that the role of every device in the backup is determined by the priority
parameter of the device. In the preemption mode, the device with the highest priority and
virtual IP address obtained will become the active (master) device, and the other devices
with lower priorities in the same backup group will become the backup (or listening) devices.
Once the VRRP function is enabled, the default priority of the VRRP group is 100.
Command
DGS-3610(config-if)# vrrp group priority
level
DGS-3610(config-if)# no vrrp group priority
[level]
The priority level range is 1~254. If the VRRP virtual IP address is the same as the actual IP
of the Ethernet interface, the priority of the corresponding VRRP group is 255. Now no

When the VRRP timer learning function is not configured, the same VRRP
advertisement interval shall be set for the same VRRP group; otherwise,
the routers in the standby status will drop the received VRRP
advertisement.
