OpenStack Networking Cookbook

Creating a Network with a specific VNI

In this recipe, we will see how to create a VXLAN-based virtual network using a specific VNI. Normally, Neutron would automatically allocate a VNI for a VXLAN-based virtual network from the range of available VNIs, but there are situations when users need a network with a specific VNI. In such cases, an OpenStack administrator can create a virtual network with a manually assigned VNI.

• An administrative level access to OpenStack
• The Network name
• A VNI for the virtual network
