Vlan trunk over wireless bridge

I have 2 subnets and want to send to separate building with wireless bridge. Bridge is currently working with just one subnet, but I need to take the second one to the other building. I want to add an RB260 switch on each side of the bridge to combine and separate the vlans. The bridge is made by 2 LHG52ac routers. Can this be done? And if yes any help would be appreciated.

I’ve done this in a test environment. This is the assumption you are running the newer wifi-qcom. Also take with a grain of salt as this is coming from memory as I haven’t done it in a little bit.

On LHG52ac acting as AP
Configure WiFi interface as AP mode. (Do not set datapath)
Add the WiFi interface to the bridge
Configure WiFi interface as a trunk via /interface/bridge/vlan as you normally would any other interface.

On LHG52ac acting as station
Configure WiFi interface as station-bridge mode.
Add the WiFi interface to the bridge
Configure WiFi interface as a trunk via /interface/bridge/vlan as you normally would any other interface.
Configure the interface that’s connected to the switch as a trunk.

It should now act as a wireless bridge and passing untagged/tagged traffic (even traffic like RoMON will work)

I’ve noticed by configuring the SSID datapath (/interface/wifi/datapath add vlan-id) you’ll tag everything as one VLAN and it will also cause untagged packets like RoMON to fail.

Thank you I will try that on Monday
