Chapter 4 Viewing MPLS VPN Properties

Working with the VPN Service Overlay

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, page 4-7—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, page 4-8—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, page 4-8—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:
