Enter with 2 clients, and have one of them hold a torch inside the white cube. Look at the debug console, you should see that the client holding the torch sees OnTriggerEnter when the torch is first put in, and OnTriggerExit when the torch is moved out.
The other client will see OnTriggerEnter and OnTriggerExit spamming up their console.
