**Q: Which core OVN version should I use for my OpenStack installation?**
OpenStack doesn't set explicit version requirements for OVN installation, but
it's recommended to follow at least the version that is used in upstream CI,
e.g.:
https://github.com/openstack/neutron/blob/4d31284373e89cb2b29539d6718f90a4c4d8284b/zuul.d/tempest-singlenode.yaml#L310
Some new features may require the latest core OVN version to work. For example,
to be able to use VXLAN network type, one must run OVN 20.09+.
See :doc:`/admin/ovn/ovn` for links to more details on OVN's architecture. See :doc:`/admin/ovn/ovn` for links to more details on OVN's architecture.

OVN driver now supports VXLAN type for networks. This requires
OVN version to be 20.09 or newer.
