•Out Going VRF—The VRF routing entry that points to the other VRF in the same PE. The Out Going VRF is the VRF that is pointed to by the Cross VRF entry.

•Out Tag—The MPLS label inserted in the MPLS label stack by this PE router in order to reach the destination address that is connected to the other VRF.

•In Tag—The MPLS label used by this router in order to identify traffic arriving at the destination address, it was advertised by this PE router and is inserted in the MPLS label stack by the PE from where the traffic originated.

Working With the VPN Service Overlay

In addition to Network and Service View maps the user can select and display an overlay of a specific VPN on top of the devices displayed on the Network map in the map pane. The overlay is a snapshot of the network which visualizes the flows between the Sites and tunnel peers When one of the VPNs in the network is selected (in the Network map), the provider edge routers, MPLS routers and physical links that carry the LSP that is being used by the VPN are highlighted in the Network map and all the devices and links that are not part of the VPN are grayed out.

This enables the user to isolate the parts of a network that are being used by a particular service and this information can then be used for troubleshooting. For example, the overlay can highlight configuration or design problems when a bottleneck exists and all the Site interconnections using the same link.

---

Note If the routing information changes after the overlay is run, then the current view will not reflect this change.

---

Cisco ANA NetworkVision enables you to view overlays of specific VPNs on top of the devices displayed in physical Network maps. In addition, it enables you to view selected callouts for the links displayed on the Network map when the overlay is applied.

This section describes the following overlay functionality information:

•Selecting 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.
