User action is required to clearly associate each discovered virtual network with its correct network view in the Network View Editor. This provides additional context to collected data and enables NetMRI to fully discover and model the network topology. If you define any new network views in this step, you will also need to configure scan interfaces based on the steps in [*<u>Configuring Scan Interfaces</u>*](https://infoblox-docs.atlassian.net/wiki/spaces/NetMRI751/pages/42535130). If a network view does not have an assigned scan interface, discovery will not take place on that network.

If you do not wish to perform extensive management of VRF-based virtual networks in your deployment and receive a System Health banner alert reporting unassigned VRFs, do not ignore the alert. Simply map all the discovered VRF-based virtual networks to your existing network view (VRF examples include **(Default)** **IOS** (for Cisco IOS), **default** (for Cisco Nexus), or **master** (for JunOS), which are the global VRFs that may be present in some networks). Doing so automatically instructs NetMRI to use collected VRF data for further discovery.

> ⚠️ **Note**
> ⚠️ 
> ⚠️ In NetMRI, the SysAdmin Role has access to the Network View editor.

To add a discovered VRF to a network view, perform the following:

1. Click the **Settings** icon > **Setup **> **Network ****Views**.  
The Network Views settings page appears, listing all currently defined views.
2. Hover over the **Action** icon for the chosen network view and select **Assign**.   
The *Define and Configure Networks* editor appears in a popup window.
3. To see all currently discovered VRFs, click **Search ****VRF ****Names**.  
All discovered VRF instances in all devices are listed alphabetically. Unassigned VRFs appear in white in the left panel, and assigned VRFs are highlighted in gray. If you see more VRF entries then you can easily navigate, check the **Show ****unassigned ****VRF ****Only** check box.

> ⚠️ **Note**
> ⚠️ 
> ⚠️ Each network view must have a discovery range associated with it. For more information, see *<span style="color: #0000ff">[<u>Configuring</u>](#)</span>*<span style="color: #0000ff">[<u> </u>](#)</span>*<span style="color: #0000ff">[<u>Discovery</u>](https://infoblox-docs.atlassian.net/wiki/spaces/NetMRI751/pages/42437151)</span>*<span style="color: #0000ff">[<u> </u>](https://infoblox-docs.atlassian.net/wiki/spaces/NetMRI751/pages/42437151)</span>*<span style="color: #0000ff">[<u>Ranges</u>](https://infoblox-docs.atlassian.net/wiki/spaces/NetMRI751/pages/42437151)</span>*.

4. To see all VRFs listed as discovered on each device, click **Display** **VRFs** **per** **Device**. All VRFs are listed under their respective device names.

5. To see all VRF instances that are associated with any Network View, click **Display** **VRFs ****per ****Virtual** **Network**. All VRFs are listed under their respective virtual networks. The same network view can manage all VRFs in a single virtual network.

6. To set an entire virtual network to the selected network view, check the check box for all discovered VRF routers in the list that are identified by a specific **VRF** **Name** (such as **red** or **blue**). In this case, each instance of the same VRF in the list shows its own unique **Device** **Name**.

7. In the right panel of the editor, select the network view from the **Network** **View** drop-down to which you want to assign the virtual network.

8. Click **Add** **(–>)** to add the selected VRFs to the network view. To remove a VRF from the view, select it from the right panel and click **Remove** **(<–)**.

9. Click **Save** or **Save** **and** **Close** to commit the changes. Clicking **Save** keeps the **Define** and **Configure Networks** window open.

Your changes are saved into the network view. To begin seeing the practical effects of this action, go to **Network** **Explorer** > **Summaries** and open the **VRFs** accordion panel. Click **View** **All** **VRFs** in the panel if necessary, and click a network view link in the **Network** **View** column in the center panel.

> ⚠️ **Note**
> ⚠️ 
> ⚠️ A network view can contain different VRFs from the same router. This allows for route leaking between virtual networks.
