--- features: - | Support for Neutron distributed virtual routing has been added to the ``os_neutron`` role. This includes the implementation of Networking Guide's suggested agent configuration. This feature may be activated by setting ``neutron_plugin_type: ml2.ovs.dvr`` in ``/etc/openstack_deploy/user_variables.yml``. upgrade: - The variable ``neutron_agent_mode`` has been removed from the ``os_neutron`` role. The appropriate value for ``l3_agent.ini`` is now determined based on the ``neutron_plugin_type`` and host group membership.
