–Destination—The destination of the specific network.
–Mask—The subnet mask of the specific network.
–Next Hop—The next routing hop. This is the next CE address on the routing path. This field is empty when the routing entry goes to the PE.
–BGP Next Hop—The Border Gateway Protocol (BGP) next hop. This is the PE address from where to continue to get to a specific address. This field is empty when the routing entry goes to the CE.
–VRF Out Label—The label sent with MPLS traffic.
–VRF In Label—The label that is expected when MPLS traffic is received.
–MPLS Label—The MPLS label.
–Type—The type can be direct (local) or indirect.
–Routing Protocol—The routing protocol used to communicate with the other sites and VRFs, either BGP or local.
–Outgoing Int. Name—The name of the outgoing interface; displayed if the Routing Protocol type is local.
Step 3 When finished, press Ctrl + F4 to close the VRF Properties window.
Note You can also open a VRF table by right-clicking the virtual router in the Cisco ANA NetworkVision tree or map pane and selecting Open VRF Table. For more information about the columns displayed in the VRF Table window, see Viewing Virtual Router Properties.
Displaying VRF Egress and Ingress Adjacents
Cisco ANA enables you to view the exporting and importing neighbors by displaying the VRF egress and ingress adjacents. In addition, you can view the connectivity between the VRFs for the route targets and view their properties. For example, if VRF A retrieved route target import X, you can view all VRFs that export X as a route target whether it is in the same or another VPN.
To display the VRF egress and ingress adjacents:
Step 1 Right-click the virtual router in the Cisco ANA NetworkVision tree and choose Show VRF Egress Adjacents/Show VRF Ingress Adjacents. The Adjacents window is displayed.
Step 2 In the Adjacents dialog box, view the ingress and egress adjacent properties:
•Name—The name of the VRF as it appears in the device.
•Route Distinguisher—The route distinguisher configured in the VRF.
Note Selecting a specific VRF in the Cisco ANA NetworkVision tree pane displays the VRF properties. For more information, see Viewing Virtual Router Properties.
Step 3 When finished, press Ctrl + F4 to close the Adjacents window.
Viewing VRF Properties in the Inventory Window
You can view VRFs that are provisioned in individual devices by displaying the device inventory view and navigating to the VRF logical inventory, as shown in Figure 4-2.

Step 4 When finished, When finished, press Ctrl + F4 to close the inventory window.
Working with the VPN Service Overlay
In addition to network and service view maps, you can select and display an overlay of a specific VPN on top of the devices displayed on the network map. The overlay is a snapshot of the network that visualizes the flows between the sites and tunnel peers. When one network VPN is selected in the network map, the PE routers, MPLS routers, and physical links that carry the label switched path (LSP) used by the VPN are highlighted in the network map. All the devices and links that are not part of the VPN are grayed out.
The VPN service overlay allows you to isolate the parts of a network that are being used by a particular service. This information can then be used for troubleshooting. For example, the overlay can highlight configuration or design problems when bottlenecks occur and all the site interconnections use the same link.
Note If the routing information changes after the overlay is run, the changes will not appear in the current overlay.
The following topics describe the following overlay functionality information:
•Choosing an Overlay—Describes how to select and display an overlay of a specific VPN on top of the devices displayed on the physical network map.
•Displaying or Hiding Overlays—Describes how to display or hide a previously defined overlay of a specific VPN on top of the physical devices displayed on the physical network map.
•Displaying or Hiding Callouts—Describes how to display or hide the callouts for every link in the map pane in order to display related information.
Choosing an Overlay
You can display an overlay of a specific VPN on top of the devices displayed on the physical network map in the map pane.
To choose an overlay:
Step 1 Display the network map for which you want to create an overlay in Cisco ANA NetworkVision.
Step 2 On the toolbar, click Choose Overlay.
The Choose Overlay dialog box displays the available VPNs in the network.
Step 3 Select a VPN, then click OK.
The PE routers, MPLS routers, and physical links used by the selected VPN are highlighted in the network map. The VPN name is displayed in the title of the window.
Note The overlay is a snapshot taken at a specific point in time. To update the overlay, you must select and run it again.
You can hide previously defined VPN network information in the map pane using the appropriate toolbar buttons:
•Overlay information, such as link and layer details
•Callouts for the VPN network
Displaying or Hiding Overlays
You can quickly display or hide a previously defined overlay of a specific VPN on top of the physical devices displayed on the network map in the map pane.
