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 TX54 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.
