| The data ports of the VM are on port 35 and port 36 on br-int, VM also has a port we use for access and is on port 34. | |
| each of the two VM data ports is on its own provider network, with vlan 300 and 301; there is another VM port (port 34 on br-int) is for VM access with vlan 200 and not used for data traffic. The VM simply switch the packets between its data ports. | |
| The traffic generator has two ports, with mac address ec:f4:bb:dc:93:98 on port 1, ec:f4:bb:dc:93:9a on port 2. port1 send udp traffic destined to port2's mac and vice versa. | |
| We expect the traffic from its port1 to reach the br-int port 35 and then switched by the VM and come back on port 36 and go to | |
| port 2 of the trafficgen. | |
