hAP ac² - vlan port configuration

I’ve skimmed through referenced links (“Access Point” and “Other devices without a built-in switch chip”), but somehow I’m either dumb or (possibly both) just having hard time picturing the final image of how a functional config should look in RouterOS.

Please let me know if I’m completely wrong, but to reach a working solution I would have to do something in the lines of:

  1. Move IP from ether1 to bridge
  2. Remove interface vlan
  3. Set PVID in bridge ports (ether2,3,4)
  4. (Re)create VLAN102 in the existing bridge and tag ether1, leaving rest untagged
