Aruba Networks Version 3.3 manual Local Controller Redundancy

Configure Local Controllers to use the VIP address as their Master Controller address as follows.

Local Controller Redundancy

Local Controllers at the Aggregation layer also use VRRP instances for redundancy, but in a different model than the Master Controllers at the Management layer. In this case, the controllers operate in what is known as “Active-Active” redundancy shown in the diagram below:

Active VIP		Active VIP
Standby VIP		Standby VIP

Using this model, two Local Controllers terminate APs on two separate VRRP Virtual IP (VIP) addresses. Each Mobility Controller is the active Local Controller for one VIP address and the standby Local Controller for the other VIP. The controllers each terminate 50% load of access points. The APs are configured in two different AP groups, each with a different VIP as the LMS IP address.
