SureLink fails on the master, it will lower its priority to below 80, and the backup device will
assume the master role.
10. Configure the VRRP interface. The VRRP interface is defined in the Interface parameter of the
VRRP configuration, and generally should be a LAN interface:
To configure the VRRP interface:
a. Click to expand Network > Interfaces.
b. Click to expand the appropriate VRRP interface (for example, LAN1).
c. For backup devices, for Default Gateway, type the IP address of the VRRP interface on the
master device.
d. Configure the VRRP interface's DHCP server to use a custom gateway that corresponds to
one of the VRRP virtual IP addresses:
i. Click to expand DHCP Server > Advanced settings.
ii. For Gateway, select Custom.
iii. For Custom gateway, enter the IP address of one of the virtual IPs used by this VRRP
instance.
e. For backup devices, enable and configure SureLink on 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.
