Chapter 46 VRRP Configuration
As shown in Figure 47-3, two virtual devices are set. For virtual device 1, device A uses the
IP address 192.168.12.1 of Ethernet interface Fa0/0 as the IP address of the virtual device,
and thus device A becomes the master device and device B standby. For virtual device 2,
device B uses the IP address 192.168.12.2 of Ethernet interface Fa0/0 as the IP address of
the virtual device, and thus device B becomes the master device and device A standby. In
the LAN, hosts 1 and 2 use the IP address 192.168.12.1 of virtual device 1 as the default
gateway, while hosts 3 and 4 use the IP address 192.168.12.2 of virtual device 2 as the
default gateway. In this VRRP application, device A and router B provide the route
redundancy to share the traffic from the LAN, that is, load balancing.

VRRP Configuration Task List

The VRRP is applicable for the multicast or broadcast LANs, such as Ethernet. The
configuration of the VRRP is concentrated on the Ethernet interfaces. The configuration
tasks are as follows:
Enable VRRP backup function (required)

Set the authentication string of the VRRP backup group (optional)

Set the broadcast interval of the VRRP backup group (optional)

Set the preemption mode of device in the VRRP backup group (optional)

Set the device priority in the VRRP backup group (optional)

Set a monitored interface for the VRRP backup group

Set the VRRP broadcast timer learning function (optional)

Set the description string of device in the VRRP backup group (optional)

Not all of above are required here. The tasks to be completed for a VRRP backup group
depend on user demands.
46.3.2

Enabling the VRRP Backup Function

By specifying the backup group number and virtual IP address, you may add a backup in the
specified LAN network segment to enable the VRRP backup function of the related Ethernet
interfaces.
Command
DGS-3610(config-if)# vrrp group ip ipaddress
[secondary]
DGS-3610(config-if)# no vrrp group ip ipaddress
[secondary]
The range of the backup group number group is 1~255. If the virtual IP address ipaddress is
not specified, the router will not participate in the VRRP backup group. If the secondary
