I think I may have an issue with premption or possibly dont understand its default behavior. I do not want Premption in case I have a controller that may be continuosly rebooting.. or if I want to take the Master down for maintenance and dont want AP's to fall back to the original master controller until I am ready.
I have VRRP setup between Master/Standy as well as Master-Redundancy enabled. I have not configured pre-emption (default state).
When I shut the VRRP instance on the Master to force failover to the Standby, this works fine. The Standby assumes the Master role for both the VRRP instance as well as the Master-Redundancy state. Great! I can no-shut the VRRP on the original Master and it maintains its state as backup. Again, perfect. However, when I reboot the original Master, when it comes back up, it resumes the Master state. Why? If pre-empt is disabled, I would not think this should happen.
