Refer to the exhibit.

A network has one master and two local controllers with 200 APs that provide an employee WLAN. The Master controller is configured with two AP groups, North and South. The Local 1 and Local 2 controllers are located in the data center and are configured with VRRP instances. The customer would like to utilize both controllers for active-active local controller redundancy.
How should the network administrator configure the controller VRRP instances in the AP groups for active- active controller redundancy?
