Wired

Ok, this is probably a stupid question but I have never came across this scenario and wondering if it is possible.

Scenario: Shared office space with 2 companies on single network physically.

All the servers, workstations, etc. are connected on the same network cables through out the office space but will have a mix on any given day of employees from the 2 companies. Their devices are associated to their own respective domains.

Is there a way to configure the switches to route traffic to/from a PC on Domain A to the Domain A's firewall and vice versa for Domain B? I am looking at a hybrid business model where the desks will not be permanent but rather a floating desk as first come, first serve. I know I can setup VLANs but the part my brain is not able to comprehend is how to route the traffic to isolate the 2 domains.


Any suggestions and/or guidance would be greatly appreciated!
