I have a question regarding design and protocol. I have a network consisting of four buildings all connected through a combination of fiber and MPLS. These building need wireless. I would like to implement a solution using one 4402 WLC with LAPs in the buildings. My question regards the REAP and H-REAP protocols. Each building will have servers that the wireless users will need to access. I do not want all the traffic coming over the WAN only to return the way it came. It seems like implementing the LAPs with H-REAP is the solution to my problem. I want to ask the community if this seems correct and also ask anyone to add any other information that may be helpful as I may be missing something.
My concern is unnecessary traffic on the WAN. I want the ease of managing one controller without wasting bandwidth on my WAN. Is there a way to have traffic that is destined for a server that may be local to the LAP not use the WAN? What if the wireless users are on a seperate VLAN/subnet than the servers in the same building?
Please ask any questions if possible. I hope I was clear enough.
