I am learning about layer 2 networking, arp, cam tables, mac addresses etc. I will like to see some of these things in action but I do not have access to physical hardware now, does anyone know of a virtual software I can use? I know there are virtualised implementation of certain network functionality, for example https://frrouting.org/ for routing, but I am not interested in routing now, but just switching. So anyone knows something like frrouting but for switching, where I can run which will have virtual ports, and I can connect processes to these virtual ports?
