Note If a path is not specified to an icon, the default VPN icon is used (for more information about icons, see Table 17-6).

• Description—(Optional) An additional VPN description.

Step 4 Click OK.

The new VPN is added to the VPN list in the Add VPN dialog box.

For more information about loading the newly created VPN in the service view map, see Adding a VPN to a Map.

Adding a VPN to a Map

You can add a VPN to a map view if the VPN was previously created by a user or discovered by Prime Network and are not currently displayed in the map.

Note Adding a VPN affects other users if they are working with the same map.

To add an existing VPN to a map:

Step 1 In the Vision client, display the map to which you want to add the VPN.

Step 2 Do either of the following:

• From the File menu, choose Add to Map > VPN > Existing.
• In the main toolbar, click Add to Map, then choose Add to Map > VPN > Existing.

The Add VPN dialog box is displayed.

Step 3 Do either of the following:

• Choose a search category, enter a search string, then click Go to narrow search results to a range of VPNs or a specific VPN. Search categories include:

– Description

– Name

The search condition is “contains.” Search strings are case-insensitive. For example, if you choose the Name category and enter “net,” the Vision client displays VPNs “net” and “NET” in the names whether net appears at the beginning, middle, or at the end of the name.

• Choose Show All to display all the VPNs.

Step 4 Select the VPN that you want to add to the map.

Tip Press Shift or Ctrl to choose multiple adjoining or nonadjoining VPNs.

Step 5 Click OK.

The VPN is displayed in the navigation pane and the selected map or subnetwork in the Vision client window content pane. In addition, any tickets are displayed in the ticket area.

When a VPN service is added to a map, then a new link is available between the ethernet flow point that represents the pseudowire headend port and the site in the VPN to which it is connected.

If your network has a L3VPN connected to a pseudowire via a PWHe, then EVC will also include the L3VPN in the EVC that contains the pseudowire.

Removing a VPN from a Map

You can remove one or more VPNs from the current active map. This change does not affect other maps. Removing a VPN from a map does not remove it from the Prime Network database. The VPN will appear in the Add VPN dialog box, so you can add it back to the map at any time.

When removing VPNs from maps, keep the following in mind:

• Removing a VPN affects other users if they are working with the same map view.
• This option does not change the business configuration or database.
• You cannot remove virtual routers or sites from the map without removing the VPN.

To remove a VPN, in the Vision client pane or map view, right-click the VPN and choose Remove from Map.

The VPN is removed from the map view along with all VPN elements, such as connected CE devices. Remote VPNs (extranets) are not removed.

Note If the routing information changes after an overlay is applied, the changes do not appear in the current overlay. Click Refresh Overlay to update the routing information.

Moving a Virtual Router Between VPNs

You can move a virtual router (including its sites) from one VPN to another after you create a VPN and add it to the service view map.

Note Moving a virtual router moves all of its sites as well.

To move a virtual router:

Step 1 In the Vision client navigation pane or map, right-click the virtual router and choose Edit > Move selected.

Step 2 Right-click the required VPN in the navigation pane or map 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.

---

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

Applying VPN Overlays

You can select and display an overlay of a specific VPN on top of the devices displayed in a map view. 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 LSP used by the VPN are highlighted in the network map. All the devices and links that are not part of the VPN are dimmed.

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 interlinks use the same link.

To apply a VPN overlay:

Step 1 In the Vision client, display the network map on which you want to apply an overlay.

Step 2 From the main toolbar, click Choose Overlay Type and choose VPN.

The Select VPN Overlay dialog box is displayed.

Step 3 Do one of the following:

• Choose a search category, enter a search string, then click Go to narrow the search results to a range of VPNs or a specific VPN. Search categories include:

– Description

– Name

The search condition is “contains.” Search strings are case-insensitive. For example, if you choose the Name category and enter “net,” the Vision client displays VPNs “net” and “NET” in the names whether net appears at the beginning, middle, or at the end of the name: for example, Ethernet.

• Choose Show All to display all the VPNs.

Step 4 Select the VPN overlay that you want to apply to the map.

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 An overlay is a snapshot taken at a specific point in time and does not reflect changes that occur in the service. As a result, the information in an overlay can become stale. To update the overlay, click Refresh Overlay in the main toolbar.

Managing a VPN Overlay Display in the Map View

After a VPN overlay is applied to a map, you can manage its display by using the overlay tools in the main toolbar:

• To display the overlay, click Show Overlay on the main toolbar.
• To hide an active overlay, click Hide Overlay on the main toolbar.

Note The Show Overlay button is a toggle. When clicked, the overlay is displayed. When clicked again, the overlay is hidden.

• To remove the VPN overlay, choose Show Overlay Type > None.

Displaying VPN Callouts in a VPN Overlay

You can display or hide the callouts for VPN links displayed in a VPN overlay to show the details of the sites that are interlinked through the selected links. The callouts (see Figure 17-15) enable you to view the VPN traffic links for a specific link (either bidirectional or unidirectional).

The routing information is displayed as shown in Figure 17-17.

Figure 17-17 Routing Entity Table

Table 17-12 describes the information that is displayed in the Routing Entity table.

Viewing IPv4 Label in BGP Routes

The labeled BGP IPv4 (RFC 3107) enables BGP to distribute MPLS label along the routes it advertises. The label mapping information for a particular route is added in the same BGP update message that is used to distribute the route itself. The label mapping information is carried as a part of the Network Layer Reachability Information (NLRI) in the multiprotocol extension attributes. Hence, the use of any other label distribution protocol is eliminated.

The outer label again identifies the LSP and the inner label identifies the MPLS service. In this case, the RFC 3107 edge device replaces the outer label with two labels, generating a three-label stack.

In Prime Network, the IPv4 BGP Label Routing table displays incoming and outgoing labels. Path tracer follows a service that relies on RFC 3107 and it reflects the BGP label in the MPLS label stack.

RFC3107 is supported on the following device types: ASR9K, ASR901, ASR903, and ME3600/3800X.

To view the BGP label information:

Step 1 Double-click the required element in the Vision client.

Step 2 Choose Logical Inventory > Routing Entities > Routing Entity.

Step 3 In the IPv4 BGP Label Routing table, view the details of incoming and outgoing labels.

Table 17-13 describes the information in the IPv4 BGP Label Routing Table tab.

Table 17-13 IPv4 BGP Label Routing Table Properties

Viewing the ARP Table

To view the ARP table:

Step 1 Right-click the required device in the Vision client and choose Inventory.

Step 2 In the logical inventory window, choose Logical Inventory > Routing Entities > Routing Entity > ARP.

Table 17-14 describes the information that is displayed in the ARP table.

Viewing the NDP Table

Neighbor Discovery Protocol (NDP) is used with IPv6 to discover other nodes, determine the link layer addresses of other nodes, find available routers, and maintain reachability information about the paths to other active Neighbour nodes.

NDP functionality includes:

• Router discovery
• Autoconfiguration of addresses (stateless address autoconfiguration [SLAAC])
• IPv6 address resolution (replaces Address Resolution Protocol [ARP])
• Neighbour reachability (neighbour unreachability detection [NUD])
• Duplicate address detection (DAD)
• Redirection

To view the NDP table:

Step 1 Right-click the required device in the Vision client and choose Inventory.

Step 2 In the logical inventory window, choose Logical Inventory > Routing Entities > Routing Entity > ARP Entity.

Note Rate Limit information applies only to certain operating systems, such as Cisco IOS.

Table 17-16 describes the information that is displayed in the Rate Limits tab of the IP Interface Properties dialog box.

Viewing VRRP Information

Virtual Router Redundancy Protocol (VRRP) is a non-proprietary redundancy protocol that is designed to increase the availability of the static default gateway servicing hosts on the same subnet. This increased reliability is achieved by advertising a virtual router (a representation of master and backup routers acting as a group) as a default gateway to the hosts instead of one physical router. Two or more physical routers are then configured to stand for the virtual router, with only one doing the actual routing at any given time. If the current physical router that is routing the data on behalf of the virtual router fails, another physical router automatically replaces it. The physical router that forwards data on behalf of the virtual router is called the master router; physical routers standing by to take over for the master router if needed are called backup routers.

To view VRRP information:

Step 1 Double-click the required element in the Vision client.

Step 2 In logical inventory, choose Logical Inventory > Routing Entities > Routing Entity.

Step 3 In the IP Interfaces tab, double-click the required interface to view the IP interface properties. If VRRP is configured on the IP interface, the VRRP Groups tab is displayed.

Figure 17-19 VRRP Properties in IP Interface Properties Window

Table 17-17 describes the information in the VRRP Groups tab.

Viewing Label Switched Entity Properties

Logical inventory can display any or all of the following tabs for label switched entities, depending on the configuration:

• Label Switching Table—Describes the MPLS label switching entries used for traversing MPLS core networks.
• LDP Neighbours—Details all MPLS interface peers that use the Label Distribution Protocol (LDP). LDP enables Neighbouring provider (P) or PE routers acting as label switch routers (LSRs) in an MPLS-aware network to exchange label prefix binding information, which is required to forwarding traffic. The LSRs discover potential peers in the network with which they can establish LDP sessions in order to negotiate and exchange the labels (addresses) to be used for forwarding packets.

Two LDP peer discovery types are supported:

– Basic discovery—Used to discover directly connected LDP LSRs. An LSR sends hello messages to the all-routers-on-this-subnet multicast address, on interfaces for which LDP has been configured.

– Extended discovery—Used between indirectly connected LDP LSRs. An LSR sends targeted hello messages to specific IP addresses. Targeted sessions are configured because the routers are not physically connected, and broadcasting would not reach the peers. The IP addresses of both peers are required for extended discovery.

If two LSRs are connected with two separate interfaces, two LDP discoveries are performed.

• MPLS Interfaces—Contains information on MPLS interfaces and whether traffic engineering tunnels are configured on an interface.
• MPLS Label Range—Identifies whether MPLS uses static or dynamic routing, and the label range.
• Traffic Engineering LSPs—Describes the MPLS traffic engineering Label Switched Paths (LSPs) provisioned on the switch entity. MPLS traffic engineering LSP, an extension to MPLS TE, provides flexibility when configuring LSP attributes for MPLS TE tunnels.
• VRF Table—Describes MPLS paths that terminate locally at a VRF.

To view information for label switched entities:

Step 1 Double-click the required device in the Vision client.

Step 2 In the logical inventory window, choose Logical Inventory > LSEs > Label Switching.

Table 17-18 describes the information that is displayed for label switched entities.

Step 3 Double-click an entry in any of the tables to view additional properties for that entry.

Multicast Label Switching (mLADP)

Multicast Label Distribution protocol (mLDP) provides extensions to the Label Distribution Protocol (LDP) for the setup of point-to-multipoint (P2MP) and multipoint-to-multipoint (MP2MP) Label Switched Paths (LSPs) in MPLS networks. A P2MP LSP allows traffic from a single root (or ingress) node to be delivered to a number of leaf (or egress) nodes.

A MP2MP LSP allows traffic from multiple ingress nodes to be delivered to multiple egress nodes. Only a single copy of the packet will be sent on any link traversed by a multipoint LSP. Container is the holder of MPLS MLDP databases and neighbors instances for Multicast.

Cerent Trap Support

Cerent traps are alarms supported for CPT devices. There are 170 traps supported.There are various kinds of traps supported which are listed below:

• Communications
• Equipment
• Environmental
• Integrity Violation
• Quality of Service

The alarms can be categorized by their severity such as Critical, Major, Minor, Not Reported and Not Alarmed. Examples of each severity categories are as follows:

• Critical- Equipment failure
• Major- High Voltage, Battery Failure
• Minor- Loss of frame, Loss of signal
• Not Reported- Unqualified PPM Inserted
• Not Alarmed- Transit Node Clock Traceable

Change Settings in Cisco Transport Controller (CTC)

Any configurations settings made in CPT should be done through CTC. To receive traps in a particular server, that server IP needs to be entered in the device through CTC. Most of the traps are on device dependencies.

CMP Tool

The default trap format can be used to send the alarms through CMP tool which can be generated in Prime Network. The default trap format is given as follows:

Locking/Unlocking MPLS-TP Tunnels in Bulk

An MPLS-TP network has one or multiple LSPs running between endpoint devices. If you want to shutdown one of the interfaces in the network, the MPLS-TP packet must be diverted through an alternative LSP. This can be achieved by locking the interface. Before attempting to lock or unlock a tunnel, ensure that MPLS-TP tunnels have been configured for the link. Also, ensure that you have the appropriate rights (Configurator and above) to lock or unlock a tunnel.

The MPLS-TP bulk lockout/unlock option in Prime Network allows you to lock or unlock multiple MPLS-TP tunnels on different VNEs at the same time.

Your permissions determine whether you can run these commands (see Permissions for Managing MPLS Services). To find out if a device supports these commands, see the Cisco Prime Network 5.2 Supported Cisco VNEs.

Locking MPLS-TP Tunnels

To lock MPLS-TP tunnels in bulk:

Step 1 In the map view, right-click the required link and choose Properties.

Step 2 In the link properties window, right-click on the required physical link and choose the Show MPLS-TP tunnels option. The MPLS-TP tunnels’ commands dialog box is displayed, which lists all the tunnels in the selected link.

Step 3 In the MPLS-TP tunnels’ commands dialog box, choose the tunnels that you want to lock and select the Lock Out option in the Commands field.

Step 4 Click Execute Now. You are prompted to confirm the lockout operation.

Step 5 Click Yes to confirm. A message is displayed confirming that the selected tunnels have been locked. The status of the tunnel is automatically updated as Lockout(UP) after this operation.

Unlocking MPLS-TP Tunnels

To unlock MPLS-TP tunnels in bulk:

Step 1 In the map view, right-click the required link and choose Properties.

Step 2 In the link properties window, right-click on the required physical link and choose the Show MPLS-TP tunnels option. The MPLS-TP tunnels’ commands dialog box is displayed, which lists all the tunnels in the selected link.

Step 3 In the MPLS-TP tunnels’ commands dialog box, select the locked tunnels that you want to unlock and select the Unlock option in the Commands field.

Step 4 Click Execute Now. You are prompted to confirm the unlock operation.

Note If you attempt to unlock a tunnel that is not locked, a message is displayed indicating that there are no valid tunnels to perform the unlock operation.

Linear Protection for MPLS-TP

As explained earlier, MPLS-TP is the transport profile that fulfills the deployment in the network for the MPLS technology. This technology provides fast protection switching for end-to-end segments wherein the protection switching time is generally less than 50 milliseconds.

Protection switching is a mechanism wherein route and resources of a protection path are reserved for a selected working path or set of working paths.

Linear protection provides rapid and simple protection switching because it can operate between any pair of points within the network. For every working Label Switched Paths (LSP) in the network, there is a protected LSP that is not related to any other working entity. When a working LSP fails, the protected LSP is ready to take up transmission of data.

In Prime Network, the following commands are available for linear protection:

• Force Switch (Lockout)—This command is used to switch normal traffic from a working LSP to a protected LSP. This command can only be applied on a working LSP. If Force Switch is enabled, then the Working LSP becomes standby and the Protected LSP becomes active.
• Manual Switch—This command is used to switch normal traffic from a working LSP to a protected LSP. This command can be applied only on a working LSP. If Manual Switch is enabled, then the working LSP becomes standby and the protected LSP becomes active.

Note The Force Switch and Manual Switch commands are both used to switch traffic from the working LSP to the protected LSP. However, if the Manual Switch command is used, and there is a failure in the protecting LSP, then the working LSP becomes active. In case of the Force Switch command, then the working LSP does not become active if there is a failure in the protecting LSP.+

• Lockout of Protecting (Lockout)—This command is used to switch traffic from the protected LSP to the working LSP. This command can be applied only on a protected LSP. If Lockout of Protecting is enabled, then the working LSP becomes active and the protected LSP becomes standby.
• Clear Force Switch (no Lockout)—This command is used to clear the force switch on a working LSP after which the working LSP becomes active and the protected LSP becomes standby.
• Clear Manual Switch—This command is used to clear the manual switch made on a working LSP, after which the working LSP becomes active and the protected LSP becomes standby.
• Clear Lockout of Protecting (no Lockout)—This command is used to clear the lockout of protecting made on a protected LSP. The working LSP becomes standby and the protected LSP becomes active after this command is executed.

Figure 17-24 depicts the MPLS-TP topology along with the working and protected LSPs:

Figure 17-24 Linear Protection for MPLS-TP

Note In the above figure, you can find working and protected LSPs between two routers. In case of maintenance or network upgrade, the Force Switch and Manual Switch commands can be used to shut down the working LSP link. Similarly, the Lockout of Protecting command can be used to shut down the protected LSP link.
