Multiple SSIDs running 802.11r - different Mobility Domain IDs?

the "newest" information I could find:

802.11r Fast Transition how to understand that FT works?

I have not even tried to measure any difference between them. If you wish to try WPA3-SAE on your own, I'll give you some clues. The minimum config you need is to enable 802.11r, and make sure to DISABLE Generate PMK locally (ft_psk_generate_local). This option is currently not working with WPA3. OpenWRT will provide default values for the keys and identifiers, so there's no need to set them: nas_identifier is taken from the BSSID; mobility_domain will be the first 4 hex digits of the md5sum…

TLDR: starting with OpenWrt 22.03, when not using WPA3, all you need to do to make FT work is to enable 802.11r from LuCI (option ieee80211r '1' in /etc/config/wireless ). With WPA3, including mixed mode, you must disable "Generate PMK locally" in LuCI (option ft_psk_generate_local '0' in /etc/config/wireless ).
With current snapshots, the Generate PMK locally option will be automatically disabled when using WPA3, and will not even show up in LuCI.
