Routing
of 80, then weight should be set to an amount greater than 20 so that if SureLink fails on the
master, it will lower its priority to below 80, and the backup device will assume the master
role.
7. (Optional) For backup devices, enable the ability for the device to monitor the master device.
This allows a backup VRRP device to monitor the master device, and increase its priority when
the master device is failing SureLink tests. This can allow a device functioning as a backup
device to promote itself to master.

8. Configure the VRRP interface:
a. Configure the VRRP interface's DHCP server to use a custom gateway that corresponds to
one of the VRRP virtual IP addresses:
i. Set the DHCP server gateway type to custom:
(config)> network interface eth ipv4 dhcp_server advanced gateway
custom
(config)>
ii. Determine the VRRP virtual IP addresses:
(config)> show network vrrp VRRP_test virtual_address
0 192.168.3.3
1 10.10.10.1
(config)>
iii. Set the custom gateway to one of the VRRP virtual IP addresses. For example:
(config)> network interface eth ipv4 dhcp_server advanced gateway_
custom 192.168.3.3
(config)>
b. For backup devices, set the default gateway to the IP address of the VRRP interface on the
master device. For example:
(config)> network interface eth ipv4 gateway 192.168.3.1
(config)>
c. For backup devices, enable and configure SureLink on the VRRP interface.
i. Determine the VRRP interface. Generally, this should be a LAN interface; VRRP+ will
then monitor the LAN using SureLink to determine if the interface has network
connectivity and promote a backup to master if SureLink fails.
