Installing and Using OpenWrt Network and Wireless Configuration

Hi great Comunity I have this doubt
I have a few OpenWRT boxes that has 2.4ghz, and 5ghz AC. Should I set up the same "Mobility Domain" for both radios to enable 802.11r?
Thanks

yes, provided it's desirable to do FT between these radios.
