I've seen that, also with a single WLC, APs exchange neighbour informations and, based upon thins "neighbour packet", several Logical RF-subgroup are established.
What I'm trying to figure is what about this Logical RF-subgrouping when, for example, I've 3 APs that:
A <--> B <--> C
Are formed 2 Logical groups with B belonging to both of them ? ( but i suppose that could be channel flap.... )
Any help ?
