TitleHow to create Virtual Controller redundancy?
This how to describes feature implemented with WiNG 5.9 called Auto Election of VC which allows dynamic VC election and failover.

VC can be elected automatically based on rf-domain manager selection process (lowest MiNT-ID or highest model). Once Virtual Controller is elected it will install virtual management IP address as secondary address and send GARP update to the network.

Dynamic VC can be configured only on the AP Profile:
