Thanks Miguel,
if we configure it connect to a physical network and select the
Data Centre Network I assume it will create the overlay network on top of that logical
network.
Let me clarify; the network on top of which it sets up the overlay is
defined when the host is added, and is *only* used for inter-host
communication. When within the same host, it simply uses the OVS
bridge.
What (I think) you mean uses the localnet feature of OVN, where the
packets leaving the OVS bridge are forwarded to the external logical
network you configure.
These 2 concepts are unrelated.
