On pages where you can view device information, such as under **Network** **Explorer** > **Inventory**, the devices table shows a column titled **Network** **View**. Each managed device belongs to a network view, and the **Network** **View** column shows the membership of the device.

Each entry under the **Network** **View** column links to the Network Viewer window. It shows the complete list of devices that are members of the network view, broken into the following two categories:

- **Associated** **VRFs: **The complete list that contains all of the VRF instances that route traffic for the current network, including the selected local VRF of the device.
- **Imported** **VRFs: **The list of imported VRFs, which are all VRF instances imported based on routing policy from other VRF-aware devices that route traffic in the virtual network. The Route Distinguisher values identify the VRF instance to help specify how routes will be shared between different VRF networks.

Some device types do not use Route Distinguisher values (also known as Route Targets) for VRF configuration and the value will be blank as a result.

To assign other VRF instances to the current network, click the **Assign** button in the upper-right corner of the **Associated** **VRFs** section to the network editor.
