I am little bit confused about this. My friend proposed the scenario like given below using a single switch.
port 1 and 2 in the vlan 1
port 3 and 4 in the vlan 2
port 1: Machine A
Port 3: Machine B
port 2 (VLAN1 )--> Latency-Calculator/generator-Machine --> Port 4 ( VLAN 2).
this is without routing.
so when machine A communicate to the machine B, traffic passes from VLAN1 (port 2) to VLAN 2 (port 4). we have tested this one and it works fine.
I have just a single question, is there is any problem in this scenario when there are lot of traffic, any spanning tree problems or any known vulnerability. I want to know coz we are going to deploy in a very large scale and in the future if it is problem then this will be great loss.
Please give me your suggestions.
