NSX-T Edge to multiple Vlan

Hi,

I am starting to test NSX-T 2.3.0 to an test enviroment. I have 3 VLAN physical networks connectect to my vCenter via switch with a trunk. Inside m virtual network i created 3 different network with the same netowork range of the physical network. From the NSX-T guide I understood that I need a physical router to connect the multiple physical netowrk to my virtual environment.

Any idea how to solve?

Thanks
