DES-7200 Configuration Guide Chapter 1 VRRP Configuration
1-7
and handle any packets destined to the virtual router; if Accept_Mode is not configured,
it means that the IPv6 VRRP virtual router in Master state will discard any packets
destined to the virtual router, but it will not discard NA and NS packets. The
Accept_Mode is not configured by default. In addition, IPv6 VRRP Master in Owner
state will accept and handle all packets destined to the virtual router, no matter the
Accept_Mode has been configured or not.
Command Purpose
DES-7200(config-if)# vrrp ipv6 group
accept_mode
Configure the Accept_Mode of IPv6 VRRP
backup group.
DES-7200(config-if)# no vrrp ipv6 group
accept_mode
Disable the Accept_Mode of IPv6 VRRP
backup group.
1.3.7 Setting the Priority of the
Router in the VRRP Backup
Group
The VRRP protocol provides that the priority parameter of the device determines its
position in the backup group. The device that has the highest priority in the preempt
mode and has the virtual IP address becomes the active (or master) device in the
backup group. Other devices of lower priority in the same group become the backup
(or monitoring) devices. Once the VRRP function is enabled, the VRRP group has 100
as its default priority.
Command Purpose
DES-7200(config-if)# vrrp group priority level
Set the priority of the VRRP backup group.
DES-7200(config-if)# no vrrp group priority
Restore the default of the VRRP priority
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 matter whether the VRRP group in the preemption mode, the corresponding
VRRP group will be in the Master status automatically (as long as the corresponding
Ethernet interface is available).
1.3.8 Setting the Interface to be
Monitored by the VRRP
Backup Group
After the interface to be monitored by the VRRP backup group is configured, the
system will dynamically adjust the priority of the router according to the monitored
