I would like to discuss the design strategy for a WL controller 5508. The Controller is on the main site and working with 120 APs. There is another new branch Site with 15 APs (AIR-CAP26021-E-K9) and Banach Site is connected with the main site with 2 different Links (Radio Link and Private VPN with 40 MBPS.
On the branch there is main Core Switch is 4500 and plan is to create a DHCP pool on the Core for New 15APs.
I would like to know that is this necessary to be controller and APs in same IP Range or we can use the different IP Range as mention above?
No, Controller & AP can be in two different subnet.
That is one of the best practice I follow. It will help to reduce unnecessary broadcast messages hitting WLC. In this method you have to use DHCP option 43 or DNS method to discover WLC to APs.

Thanks, So it mean I can leave the controller on current subnet in Main Site and install the APs on branch Site. But what about the Address Pool ? Must use the DHCP for address Pool for branch APs or can create the Pool in Core Switch (4500) for APs ?
Kindly mention the simplest strategy .
So here will be steps:
1: Define Local DHCP Pool in L3Switch for APs with Following Commands:
