This question is regarding DHCP required and mobile supplicants in an LWAPP architecture environment. Assume DHCP required is set to true. Assume the supplicant is powered on and receives its IP address. The client then roams to a new BSS (BSS2) in the same subnet and does a DHCP request and receives notification it can continue using the one it has leased (assume it has not expired).
Question: If the client has a BSS table and roams back to the first BSS (BSS1). The client determines that it currently has an IP from BSS2 that is in the same subnet as the previous IP it was provided from BSS1 and so chooses to use the existing IP... and not do a DHCP request.
How do the controllers and APs handle this client that they have seen on this AP before and provided it an address before?
