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
Both master and backup devices:
n
A configured and enabled instance of VRRP. See
l
Enable VRRP+.
l
WAN interfaces to be monitored by using VRRP+.
l
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.
The amount that the VRRP priority will be modified when SureLink determines that the
l
VRRP interface is not functioning correctly.
Configure the VRRP interface's DHCP server to use a custom gateway that corresponds to
l
one of the VRRP virtual IP addresses.
n
Backup devices only:
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.
l
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.
