One of the SSIDs will be used for guest access and the connected vlan (the same on both controllers) should be routed on the controllers. As read in http://airheads.arubanetworks.com/vBulletin/showth
My problem is now, that the default gateways for those guest clients will also be the controller (same IP on both controllers). In case of a switch over from one controller to the other, the mac address associated to this IP will also change. But because the clients are not aware of this change, traffic will land in a black hole till their arp cache ages out.
One solution for this would be vrrp between those two controllers for the guest vlan. Unfortunately I do not have L2 connectivity between those two controllers for the guest vlan because they are in different buildings.
How are you doing those kind of setups?
Thank you very much in advance for your feedback!

Thank you for your feedback.
I agree with you that the arp cache is not an issue if the AP bootstraps. However, as far as I know, if we have a redundant master setup with a VRRP VIP address as the controller address configured in the APs, the AP will just switch over to the second master without a bootstrap. Or I'm wrong here?
