For a more detailed description of the Cisco ANA NetworkVision window, menus, and toolbars, and working with tables, see the Cisco Active Network Abstraction 3.6.6 User Guide.

Supported MPLS and VPN Technologies and Routing Protocols

Cisco ANA supports the following technologies:

• MPLS.

• Border Gateway Protocol (BGP) including route reflector scenarios.

• Layer 3 BGP MPLS VPNs as defined in RFC2547.

• Label Distribution Protocol (LDP).

• Interior Gateway Routing Protocol (IGRP).

• Cisco IGRP.

• Extended IGRP.

• Pseudowire end-to-end emulation tunnels as defined in RFC3985 and implemented for Cisco Any

Transport over MPLS (AToM). Pseudowire support is based on the Luca Martini drafts (draft-martini-l2circuit-encap-mpls-03.txt and draft-martini-l2circuit-trans-mpls-07.txt).

Note Cisco ANA supports payload types packet and cell only. For more information, see

RFC3985, Section 3.3.

• MPLS traffic engineering based on RFC2702 with Resource Reservation (RSVP) protocol for

signaling as described in RFC3209.

MPLS VPN Maps Overview

• Policy-Based Tunnel Selection (PBTS) for Cisco CRS-1 routers running Cisco IOS XR 3.6 software

in MPLS or MPLS VPN networks.

• Open Shortest Path First (OSPF).

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:

Chapter 1 Viewing MPLS VPNs

• 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.

1-2

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.

Cisco Active Network Abstraction 3.6.6 MPLS User Guide

OL-19192-01

Chapter 1 Viewing MPLS VPNs

Layer 3 VPN Business Configuration

The following business elements represent a Layer 3 VPN configuration:

• Site (IP Interface)—Represents the VPN access point on the provider edge (PE) device.

• Virtual Router—Represents a PE VRF.

The Layer 3 VPN configuration hierarchy is composed of VPN business elements that in turn contain multiple virtual routers and sites. The relationship between the contents of VPNs and virtual routers can be changed, for example, by moving a virtual router between VPNs, which causes each site connected to the moved virtual router to move as well. The relationship between virtual routers and sites cannot be changed; sites are automatically attached to virtual routers (sites cannot be moved on their own).

In the Layer 3 VPN configuration, the VPNs are created and named automatically and new virtual routers are automatically detected. The virtual router is then automatically related or matched to the VPN based on the VRF name. If there is no related or matching VPN, then a new VPN is automatically created and a VRF is assigned to it. You can then add these VPNs to a map. You can manually change the autodiscovered service information, for example, by manually creating new VPNs, by deleting empty VPNs, by renaming VPNs, and so on.

Cisco ANA can use different criteria to determine the different Layer 3 VPNs in the network and their associated virtual routers. By default, Cisco ANA uses the VRF name to determine the network VPNs.

VPN Topology Connections

Layer 2 VPN Business Configuration and Tunnels

Layer 2 VPNs are not automatically created. You create the VPNs and then add the tunnels. The following business elements represent the Layer 2 VPN configuration:

• Logical Circuit Peer (LCP)—Represents a Layer 2 tunnel edge that resides on a single device. A pair

of LCPs represents both sides of the tunnel edge.

Note A tunnel can be associated with only one VPN.

• Logical Circuit Aggregator (LCA)—Represents an aggregation of LCPs on the same device.

LCAs can be manually or automatically created:

–

Automatically—When an LCP is added to the VPN system, the system automatically creates the LCA by taking all the LCPs that belong to the same device and aggregating them into an LCA (the LCPs are automatically added under the LCA).

–

Manually—An LCA that is manually created on a specific VPN has no rules. Manually creating an LCA is a preparatory step for adding tunnels or stranded peers.

VPN Topology Connections

Cisco ANA uses route targets (based on the router configuration) to determine the topology between VRFs. Layer 3 VPN topology information is continuously updated to reflect the actual state of the network connections. Cisco ANA uses the virtual circuit (VC) ID and the router IP address (based on the router configuration) to determine the connectivity between the Layer 2 tunnel edges forming the pseudowire tunnels.

Step 1 In the Cisco ANA NetworkVision tree pane or the map pane, right-click the virtual router and choose

Edit > Move selected.

Step 2 Right-click the required VPN in the tree or the map pane to where you want to move the virtual router

and choose Edit > Move here.

Caution Moving a virtual router from one VPN to another affects all users who have the virtual router

loaded in their service view map.

Moving a Virtual Router

The virtual router and its sites are displayed under the selected VPN in the tree pane and in the map pane.

Adding a Tunnel to a VPN

You can add tunnels or partially configured tunnels to a VPN. LCPs with a missing peer are marked with the stranded icon. (For more information about icons see Tabl e 1 - 3.) Each tunnel can be associated with only one VPN.

Note The topology state between LCPs is a logical link. It does not reflect the actual state of the network.

You can do either of the following:

• Add a tunnel (LCP) to an LCA that has been manually created (see Creating an LCA, page 3-5).

• Add a tunnel (LCP) directly to a VPN, in which case the LCA is automatically created beneath the

VPN.

To add a tunnel to a VPN, complete the following steps.

Step 1 In the Cisco ANA NetworkVision tree or map pane, right-click an LCA or VPN and choose Top o lo g y >

Add Tunnel.

The Add Tunnels dialog box (Figure 3-1) displays tunnels not currently attached to a VPN. The Tunnels tab displays the list of pseudowire tunnels (including both tunnel edges). The Stranded Peers tab displays the list of partially configured tunnel edges, so you can add an LCP without its peer, for example, if a tunnel is partially managed, an agent fails to load, or a device is incorrectly configured.

Figure 3-1 Add Tunnels Dialog Box

Step 2

Select the tunnel or stranded peer and click Add.

One of the following occurs:

• If the tunnel or stranded peer is added under an LCA, the link between the peers appears in the map

pane.

• If the tunnel or stranded peer is added under a VPN, Cisco ANA detects the starting point of the

PWE3 tunnel edges and groups all the LCPs that start at the same device together into an LCA (aggregation) under the VPN.

Note If a tunnel exists between VPNs, for example, an extranet tunnel, add a tunnel to one VPN and

then move one LCP (peer) to the VPN with which you want to create the extranet tunnel.

Removing a Tunnel

You can remove a tunnel that was added to an LCA or VPN. To remove a tunnel, in the Cisco ANA NetworkVision tree or map pane, right-click the LCA or VPN and choose Topology > Remove Tunnel.

Both tunnel sides are removed from the map. You view them in the Add Tunnels dialog box. If the deleted tunnel formed part of an LCA that was created manually, the LCA is still displayed in the tree or map pane. If the deleted tunnel formed part of an LCA that was created automatically, the LCA is removed from the tree or map pane, provided no other LCPs exist in the LCA.

Note You cannot view MPLS TE tunnels in VPN service view maps. However; you can view the device and

topology information. For more information, see the “Viewing MPLS TE Tunnel Information” section

on page 5-13.

Creating an LCA

You can manually create an LCA and populate it by moving LCPs and tunnels to it. Refer to the “Moving

an LCP” section on page 3-6 and the “Adding a Tunnel to a VPN” section on page 3-3.

To create an LCA:

Step 1 In the Cisco ANA NetworkVision window tree or map pane, right-click the VPN and choose Create

LCA.

Step 2 In the Create LCA dialog box, enter a unique name for the new LCA.

Step 3 Click OK.

The new LCA is created. It appears in the tree pane in the Cisco ANA NetworkVision window, beneath the selected VPN, and also appears in the map pane.

Moving an LCA

Creating an LCA

You can move the LCA to another VPN in the service view map. When you move an LCA, all the LCPs it contains also move.

To move an LCA:

Step 1 In the Cisco ANA NetworkVision tree or map pane, right-click the LCA and choose

Edit > Move selected.

Step 2 Right-click the VPN to which you want to move the LCA and choose Edit > Move here.

The LCA moves to the selected VPN and is displayed in the tree and map panes for the selected VPN.

Note All the LCPs move with the LCA.

Deleting an LCA

You can delete an LCA if it was manually created and either has no LCPs or all the LCPs have reconciliation icons. (You can also move the LCA to another VPN using the “Jumping to an Adjacent

LCP” section on page 3-6.)

To delete the LCA:

OL-19192-01

Step 1 In the Cisco ANA NetworkVision tree or map pane, right-click the required LCA and choose Delete.

Step 2 Click Ye s on the confirmation.

The selected LCA is deleted from the database and service view maps of all users.

Moving an LCP

You can move an LCP to another VPN or LCA in the service view map.

To move an LCP:

Step 1 In the Cisco ANA NetworkVision tree or map pane, right-click the LCA and choose

Edit > Move selected.

Step 2 Right-click the VPN or LCA to which you want to move the LCP and choose Edit > Move here.

The LCP moves to the VPN or LCA and is displayed in the tree and map panes of the selected VPN or LCA.

Note If an LCP is moved to a VPN, an LCA is automatically created for it.

Chapter 3 Managing VPN Business Configurations

Jumping to an Adjacent LCP

If a service view map displays multiple tunnels, you can quickly access the selected LCP peer appearing in the same map.

To jump to the adjacent LCP, in the Cisco ANA NetworkVision tree or map pane, right-click the required LCP and choose Jump to Adjacent.

The adjacent LCP is highlighted in the tree pane and map pane.

Renaming a Business Element

To rename business elements in service view maps:

Step 1 In the Cisco ANA NetworkVision tree or map pane, right-click the business element and choose

Rename.

Step 2 In the Rename Node dialog box, type a new name.

Step 3 Click OK.

The changed business element name appears in the Cisco ANA NetworkVision tree and map panes.

3-6

Note Renaming a business element affects all users who have the business element loaded in their

service view maps.
