We have already seen situations where only the administrative users can create a Network. For example, only the administrators can create a Flat Network or a Network with a specific VLAN ID. In addition, we have seen that the administrative users can assign a Network to a particular tenant.
OpenStack also allows administrators to share a Network among all the tenants. This recipe shows you how to accomplish this.
In order to create a shared network, you will need the following information:
The Network name
The Network type—for this recipe we will use a Flat Network
The physical Network name—this information was configured in the ML2 plugin configuration file
