Thanks for your so detailed explanation!

If I understand it correctly (Please correct me if I misunderstood this : ) :

• After I using L2Bridge to connect to two interfaces at two nodes
• the two “eth1” interfaces in these nodes are “physical” connected by a “cable”.
• Therefore, I can assign IP/subnet mask to each “eth1”, and manually set route in each node.
• Then, I can ping from one node to another node through “eth1”.
• If two nodes are located at different sites, I should use L2P2P (with QoS).
• If I have more than two nodes at two sites, I should use L2S2S (without QoS).

I used the management interface, eth0, for the testing. I believe it would be the case why the connection is so slow.

Could you share with me some resources about how to configure eth1 correctly? I don’t know how to use eth1 at one VM to connect eth1 at another VM.

In addition, could you share with me some resources about the difference between  “L2Bridge” and “L2STS”?  Which one should I use in the test?
