We looked at it (802.11r) when we first deployed the 9800s on our network but took a pass pass based on the sheer size and the fact that we have no control over the devices students add to our network. We are thinking of evaluating it again to potentially reduce CPU load for intra-WLC roams.
Does anyone here have any experience using this on very large environments? Your feedback would be greatly appreciated if you have.
Cheers,
Larry
