Hi experts,
I have to implement a network for three sites. The sites are separated geographically and connnected through a MPLS network. The network would consist of a master controller in the main site, and three local controllers, one per-site. Let's say:
Site A: Master controller and local controller.
Site B: Local controller.
Site C: Local controller.
Customer has no money for the three local controllers, so for one site there are two options. One, to have a cluster of IAPs, or two, connect the APs of this site to the local controller of other site (for example, connect the APs of site C to the local controller of Site B).
For site A and site B there is no problem since the local controller and APs would be in the same site connected through a switched network. But for site C, is there any inconvenient for the second option? I mean, would be any problem or the performance would be lower taking into account the controller and the APs wouldn't be connected directly but through a MPLS network?
Regards,
Julián
