Your understanding is correct.  To get what you want, you need to have 
something actively programming flows.  If you have a simple topology, it 
wouldn't be hard to just add appropriate flows using "ovs-ofctl".  If you want 
to do something more complex, you could look at a central controller-based 
network virtualization solution.  There are a few of them out there.

One option is OVN, which started shipping with OVS 2.5.  It's still a work in 
progress, but it has supported basic L2 connectivity over tunnels for about 
year now.
