Routing
Interface: The network interface.
Format:
/network/interface/defaultip
/network/interface/defaultlinklocal
/network/interface/lan
/network/interface/loopback
/network/interface/modem
Current value:
(config)> network vrrp test interface
b. Set the interface, for example:
(config)> add network vrrp VRRP_test vrrp_plus monitor_interface end
/network/interface/modem
(config)>
c. (Optional) Repeat for additional interfaces.
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
(config)>
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
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.
(config)> network vrrp VRRP_test vrrp_plus monitor_master true
(config)>
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)>
