6. Set the amount that the device's priority should be decreased or increased due to SureLink

connectivity failure or success:

(config)> network vrrp VRRP_test vrrp_plus weight value

where value is an integer between 1 and 254. The default is 10.

Along with the priority settings for devices in this VRRP pool, the amount entered here should

be large enough to automatically demote a master device when SureLink connectivity fails. For

example, if the VRRP master device has a priority of 100 and the backup device has a priority

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

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.

(config)> network vrrp VRRP_test vrrp_plus monitor_master true

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

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

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

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
