We have a set of Mikrotik RB433AH with “roam” configuration using EoIP Tunnel and using just one Hotspot. The current license is L5, with max 500 active clients. Because of this limitation, I have a situation that forces me to acquire the L6 license for unlimited active clients scenario. So, my doubt is: how many licenses I must have for this situation? All RBs must be a L6 license too?
