To clarify, I believe you're talking about the first script from the
tutorial [1], which is:


Most of that script is all configuring logical topology.  OVN does
nothing to the network until ovn-controller sees a port appear on br-int
that maps to a logical port.  This mapping is done by setting the
"iface-id" to the name of the logical port.

Once ovn-controller has mapped a port on br-int to a logical port, it
can configure the switch appropriately for that port.

Does that make sense?
