Configure VRRP+
VRRP+ is an extension to the VRRP standard that uses SureLink network probing to monitor
connections through VRRP-enabled devices and adjust devices' VRRP priority based on the status of
the SureLink tests.
This section describes how to configure VRRP+ on a IX20 device.
Required configuration items
n
Both master and backup devices:
l
A configured and enabled instance of VRRP. See
for information.
l
Enable VRRP+.
l
WAN interfaces to be monitored by using VRRP+.
Note
SureLink is enabled by default on all WAN interfaces, and should not be disabled on
the WAN interfaces that are being monitored by VRRP+.
If multiple WAN interfaces are being monitored on the same device, the VRRP priority will
be adjusted only if all WAN interfaces fail SureLink tests.
l
The amount that the VRRP priority will be modified when SureLink determines that the
VRRP interface is not functioning correctly.
l
Configure the VRRP interface's DHCP server to use a custom gateway that corresponds to
one of the VRRP virtual IP addresses.
n
Backup devices only:
l
Enable and configure SureLink on the VRRP interface.
l
Set the IP gateway to the IP address of the VRRP interface on the master device.
Additional configuration items
n
For backup VRRP devices, enable the ability to monitor the VRRP master, so that a backup
device can increase its priority when the master device fails SureLink tests.
