Palo Alto Diagram

My question is on the diagram of Palo Alto firewall.
As explained in the video , that we create sub interface on e1/1 for inside ,outside and dmz.
I was not able to do the same on Eve-ng as 1 interface could only be mapped once.

Kindly help me understand if I missed on something or this will not work in EVE-ng environment

Warm Regards
