Chapter 1 Viewing MPLS VPNs

MPLS VPN Maps Overview

Cisco ANA automatically discovers MPLS VPNs and displays their configurations and topologies in service view maps. The physical and logical inventory information that Cisco ANA discovers about network devices is displayed in network maps. Cisco ANA may contain multiple maps, service view as well as network. The VPNs that are discovered and displayed in service view maps allow you to drill down into specific VPNs and view information about the elements they contain.

Note In previous releases, network maps displayed only devices, and service view maps displayed only VPNs. Starting in Release 3.6.6, devices can be displayed in service view maps, and VPNs can be displayed on network maps.

Cisco ANA can automatically discover Layer 3 VPNs in the network and their associated virtual routers. After creating an MPLS VPN map, you can, for example:

Add or remove VPNs that were automatically discovered by the system based on the automatically discovered information from the network.

View business element properties.

Select and move logical circuit peers (LCPs) and logical circuit aggregators (LCAs).

View VPN logical topology and understand the connectivity between sites.

View VPN topology.

Select and display an overlay of a specific VPN on top of the devices in the map.

View logical inventory.

Add tunnels to a service view map and view Layer 3 pseudowires and MPLS traffic engineering (TE) tunnel information.

View the active faults and tickets generated by Cisco ANA for the devices in the map.

Identify extranets.

VPN Business Configurations

Cisco ANA allows you to map service-related information to network resources by using a business element as a wrapper for a network element (NE) or service. VPNs are considered business elements because they represent interconnected sites that form a single VPN over a public network. Sites can be connected over virtual routing and forwarding (VRF) instances or through pseudowire tunnels.

The Cisco ANA business element containment hierarchy reflects the VPN structure. Business elements are available through the Northbound Interface (NBI) as well as in Cisco ANA NetworkVision. Any changes that are made to the business configuration are reflected in all maps. For example, if a link is removed, the link removal is reflected in all the maps.
