For this reason they can only be created by an admin and you should also consider keeping them private and granting access to tenants using RBAC.</div><div><br></div><div>We use them extensively and they work well. We're able to add new networks as needed by trunking the VLAN of the desired network to the compute and controller nodes and then creating the new provider type network in neutron. Providing a segmentation id when creating the network allows Open vSwitch to tag the traffic with the proper vlan before it leaves the compute node.</div><div><br></div><div>Regards,</div><div><br></div><div>John Petrini</div></div>
