Like this?
vm01-------------------|
|------------------vm03

br1(vxlanport1)------------br-int1=================br-int2----------(vxlanport2)br2
vm02-------------------|
|-------------------vm04

What is the need for the bridges br-int1 and br-int2? Why is it not
possible without them(as the topology shown earlier in this thread)?
