Code Issues Proposed changes
neutron/doc/source/admin/ovn/features.rst
Slawek Kaplonski cd66232c2b Merge networking-ovn documentation into neutron 
It also adds 2 sample of devstack's local.conf file
for deploying Neutron with OVN mechanism driver.

Needed to create PNG files out of the existing SVG
ones in order to pass the pdf doc build.

Features

Open Virtual Network (OVN) offers the following virtual network services:

  • Layer-2 (switching)

    Native implementation. Replaces the conventional Open vSwitch (OVS) agent.

  • Layer-3 (routing)

    Native implementation that supports distributed routing. Replaces the conventional Neutron L3 agent. This includes transparent L3HA :doc::routing support, based on BFD monitorization integrated in core OVN.

  • DHCP

    Native distributed implementation. Replaces the conventional Neutron DHCP agent. Note that the native implementation does not yet support DNS features.

  • DPDK

    OVN and ovn mechanism driver may be used with OVS using either the Linux kernel datapath or the DPDK datapath.

  • Trunk driver

    Uses OVN's functionality of parent port and port tagging to support trunk service plugin. One has to enable the 'trunk' service plugin in neutron configuration files to use this feature.

  • VLAN tenant networks

    The ovn driver does support VLAN tenant networks when used with OVN version 2.11 (or higher).

  • DNS

    Native implementation. Since the version 2.8 OVN contains a built-in DNS implementation.

The following Neutron API extensions are supported with OVN:
