Could someone explain the advantages or differences in using HREAP (when the traffic is centrally switched), to just using the APs in local mode with a centralized WLC?
Scenario- 1 HQ and several branch offices. All resources are at the HQ including DHCP and internet break-out.
In local mode, all traffic will get tunneled back to the wlc. Also in local mode constanc communication is required from AP to the WLC. In h-reap, you can still have some ssid's locally switched and some that are centrally switched. In most of my installs, clients that have high bandwidth WAN like a gig, have no issues with bandwidth. So the answer is yes... there is more traffic in local mode than in h-reap (locally or centrally switched).
