Configuring the Local Controller for Redundancy
You can use either the WebUI or CLI to configure VRRP on the local controllers. For this topology, it is
recommended you use the default priority value.
In the WebUI
1. Navigate to the Configuration > Advanced Services > Redundancy page for each of the local
controllers.
2. Under Virtual Router Table, click Add to create a new VRRP instance.
3. Select the IP version.
4. Enter the IPv4\IPv6 Address for the virtual router. Select the VLAN on which VRRP will run. Set the Admin
State to Up.
5. Configure other VRRP parameters as described in the table below.
6. Click Done, then save your configuration.
Parameter Description
IPVersion Select IPv4 \ IPv6 from the drop-down list box.
Virtual Router ID The ID uniquely identifies this VRRP instance. For ease in administration, you
should configure this with the same value as the VLAN ID.
Advertisement Interval
(secs)
This is the interval, in seconds, between successive VRRP advertisements sent
by the current master. The default interval time is recommended.
Default: 1 second
Authentication Password This is an optional password of up to eight characters that can authenticate
VRRP peers in their advertisements. If this is not configured, there is no
authentication password.
Description This is an optional text description to describe the VRRP instance.
IP \ IPv6 Address Based on the selection made in the IP version field, either IPAddress \ IPv6
Address is displayed. This is the virtual IP address that will be owned by the
elected VRRP master. Ensure that the same IP address and VRRPID is used on
each member of the redundant pair.
Note: The IP address must be unique and cannot be the loopback address of
the controller. A maximum of only two virtual IPv6 addresses can be
configured on each VRRP instance. Only IPv6 address format is supported for
the v6 instance.
Enable Router Pre-
emption
Selecting this option means that a controller can take over the role of master if
it detects a lower priority controller currently acting as master.
