VNIs

VNIs

Virtual network identifiers (VNIs) are used in VXLAN encapsulation to provide Layer 2 separation for the overlay traffic in your data center fabric. (For more information about VNI usage, see Virtual Networks.

You'll create VNI pools in the Resources section, then when you create virtual networks and routing zones you'll assign those pools. Resources from the pool are automatically pulled, as needed.

If you need to assign a specific VNI, you can assign it manually

VNI Pool Details

VNI pools include the following details:

Pool Name A unique name to identify the resource pool
Total Usage Percentage of VNIs in use for all ranges in the resource pool. (Hover over the status bar to see the number of VNIs in use and the total number of VNIs in the pool.)
Range Usage The VNIs included in the range and the percentage that are in use. (Hover over the status bar to see the number of VNIs in use and the total number of VNIs in that range.)
Status Indicates if the pool is in use

You can delete VNI pools as long as none of the VNIs within the pool are in use.
To delete a VNI pool using the GUI:
  1. From the left navigation menu, navigate to Resources > VNI Pools and click the Delete button in the Actions panel for the pool to delete.
  2. Click Delete.
