a way to combine VLAN 13 and untagged traffic on a bridged physical interface where I have my AP connected.
Is it possible to switch the untagged traffic on L2 and route all VLAN13 traffic while these are on the same interface? Can someone explain this straight-forward setup to me?
Well trying to catch what you want to understand.
There is L2 connectivity needed, so indeed a bridge is required.
Now your requirements:
- combine untagged and VLAN13 on a physical interface, points to a bridge with a “hybrid” port connected. Hybrid being a combination of tagged and untagged.
- There can only be one untagged data stream, and multiple VLAN.
- The untagged data in handled as a VLAN internally in the bridge. This tag/untag operation is set with the PVID of the bridge port for that interface.
Read only recent posts and documents on VLAN , as RouterOS capabilities have changed over time, and the Bridge VLAN Table capability is larger than most Switch based VLAN tables. So check if Switch or Bridge capabilities are discussed. (Switch based is discussed in cases where hardware offloading to the switch chip is wanted)
In your case some good documents on PVID are:

You probably will need at least one hybrid port (combining untagged and VLAN 13).
To route VLAN13, a “/interface VLAN” is needed , and VLAN13 should then NOT be forwarded to that bridge port (see: Bridge VLAN Table) where you want it routed instead https://help.mikrotik.com/docs/display/ROS/VLAN
