R320 when working as Unleashed Master role can facilitate mesh setup and configuration but it can’t participate in mesh operation or act as mesh node like running as RAP or MAP or eMAP.
For example if you have 1 x R320 and 3 x R550, then you can choose R320 as Unleashed Master and setup mesh network while the actual mesh will only be running on the R550 (ie: first R550 as RAP and the other two R550 as MAP) and the R320 can still provide WLAN service but not involve in mesh operation.
