Second SSID in same subnet

Hi forum
I am trying to get a second SSID in my 5 GHz Wifi which should be in the same subnet the the other SSID.
I was looking at this guide for orientation but I did not succeed.
Is this even possible?

Just add another wireless SSID to the same radio and attach the network of your choice: Multi SSID.

your device needs to support virtual APs:

iwinfo | grep VAP
          Supports VAPs: yes  PHY name: wl0
