OpenStack-Ansible supports the use of a single interface or set of bonded
interfaces that carry traffic for OpenStack services as well as instances.
The following diagram demonstrates hosts using a single interface:

The following diagrams demonstrate hosts using a single bond with OVN.
In the scenario below only Network node is connected to external network and
computes do not have external connectivity, so routers are needed for external
connectivity:

The following diagram demonstrates a compute node serving as an OVN gatway.
It is connected to the public network, which enables to connect VMs to public
networks not only through routers, but also directly:
