802.11be enabled on all bands — 2.4 GHz, 5 GHz, and 6 GHz radios must each have 11be enabled (and be enabled).
Same SSID on all VAPs participating in the MLO group.
Same password on all VAPs participating in the MLO group.
Security mode:
- 2.4 GHz & 5 GHz → WPA3-Personal-Transition, WPA3-Personal-Compatibility or WPA3-Personal
- 6 GHz → WPA3-Personal
All participating VAPs enabled (one link per radio; STA/mesh VAPs excluded).

Mismatched SSID, password, or an incompatible security mode causes that band's link to be silently excluded from the MLD group.

Enable 3-link MLO for private VAPs via TR-181 DM

Banana Pi MLO config

Configuration for Banana Pi is slightly different from the ones we have for XB platform devices.

we do not set Link_IDs. These are set by hostapd/rdk-wifi-hal and should be left untouched.
legacy: there is still partial dependency left on InterfaceMap.json which will be removed in the future. Currently, the VAPs belonging to MLD group have to have common MLD name defined in the JSON.
legacy: wireless MLD device has to be precreated prior to setup of the MLD

Below is how we setup MLO for VAPs as well as listings showing the legacy fields mentioned. Legacy fields will be made obsolete with further development and alignment toward unified handling.

#legacy nvram/IntefaceMap.json entry
{
"InterfaceName": "wifi2",
"MldName": "mld0",
"Bridge": "brlan0",
"vlanId": 0,
"vapIndex": 16,
"vapName": "private_ssid_6g"
}
