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:
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.
