[ovs-discuss] [ovn-controller-vtep] Will ovn-controller-vtep write vtep db

[Macauley Cheng]

I try to setup the ovn environment with ovn-controller-vtep. But I found ovn-controller-vtep won’t write anything to vtep database.
According to OVN architecture document, the tunnel key in ovnsb-db was filled by ovn-controller-vtep and it is as described. 
But I can’t find anyway that ovn-controller-vtep will setup vtep database, is this normal?

Is their any example to use ovs to simulate the hardware switch? Currently I use real hardware switch to test.
