We are planning to deploy 5 wlan controllers in 5 different sites and one master controller in datacenter.
all 5 sites traffic will get diverted through datacentre only though MPLS
site A- local
As we can go with N+1 redeundancy model. but in every site if we have 300-400 AP's. If controller goes down in Site A. It will take longer time for Ap's to take backup LMS(datacentre controller) and if all ap's are terminating in datacentre .
I guess MPLS traffic will be more and users using internet from that sites will face slowness ri8?? is this the case or do we any alternate solution .
In case site A controller and Site B controller goes down, there will be huge traffic in MPLS link and it may go down ri8? ofcoure it depends on MPLS bandwidth
Is there any option like, if site A controller goes down, Ap's in Site A can do local forwarding instead of taking up controller in datacentre.

And for all the 5 sites, we are planning to go with NAC solution.
We are planning to have clearpass 5k for all 5 sites and will place it in datacentre.
Is this recomended approach. to have radius authenticating server in datacentre which is connected to sites through MPLS where we have controller.
