User Roles Required to Work with MPLS Networks
This topic identifies the roles that are required to work with MPLS networks. Prime Network determines whether you are authorized to perform a task as follows:
•
For GUI-based tasks (tasks that do not affect elements), authorization is based on the default permission that is assigned to your user account.
•
For element-based tasks (tasks that do affect elements), authorization is based on the default permission that is assigned to your account. That is, whether the element is in one of your assigned scopes and whether you meet the minimum security level for that scope.
For more information on user authorization, see the Cisco Prime Network 3.9 Administrator Guide.
The following tables identify the tasks that you can perform:
•
Table 17-1 identifies the tasks that you can perform if a selected element is not in one of your assigned scopes.
•
Table 17-2 identifies the tasks that you can perform if a selected element is in one of your assigned scopes.
By default, users with the Administrator role have access to all managed elements. To change the Administrator user scope, see the topic on device scopes in the Cisco Prime Network 3.9 Administrator Guide.

Working with MPLS-TP Tunnels
MPLS-Transport Profile (MPLS-TP) is considered to be the next generation transport for those using SONET/SDH TDM technologies as they migrate to packet-switching technology. Although still under definition by the IETF, MPLS-TP provides:
•
Predetermined and long-lived connections.
•
Emphasis on manageability and deterministic behavior.
•
Fast fault detection and recovery.
•
Inband OAM.
MPLS-TP features include:
•
Manually provisioned MPLS-TP LSPs.
•
Reserved bandwidth for static MPLS-TP LSPs.
•
One-to-one path protection for MPLS-TP LSPs.
•
Working/Protected LSP switchover.
•
Continuity Check (CC), Proactive Continuity Verification (CV), and Remote Defect Indication (RDI) based on BFD.
•
New fault OAM functions resulting from the MPLS-TP standardization effort.
Prime Network automatically discovers network MPLS-TP tunnels from end to end, including LSPs, tunnel endpoints, and bandwidth. Network LSPs contain LSP endpoints and midpoints and are identified as working or protected.
Prime Network links the MPLS-TP tunnel components appropriately, provides a visual representation in Prime Network Vision maps, and displays the properties in logical inventory.
Prime Network employs warm start technology when rebooting. That is, when rebooting, Prime Network compares existing MPLS-TP tunnel information to topology changes that occur while Prime Network is down and updates MPLS-TP tunnel accordingly when Prime Network returns to operation.
The following options are available for working with MPLS-TP tunnels in Prime Network Vision:
•
Adding an MPLS-TP Tunnel
•
Viewing MPLS-TP Tunnel Properties
•
Viewing LSPs Configured on an Ethernet Link
•
Viewing LSP Endpoint Redundancy Service Properties
•
Applying an MPLS-TP Tunnel Overlay
•
Viewing MPLS-TP BFD session properties—See Viewing BFD Session Properties.
Adding an MPLS-TP Tunnel
Prime Network Vision automatically discovers MPLS-TP tunnels, endpoints, and midpoints and enables you to add MPLP-TP tunnels to maps.
To add an MPLS-TP tunnel to a map:
Step 1
In Prime Network Vision, display the map to which you want to add the MPLS-TP tunnel.
Step 2
Do either of the following:
•
From the File menu, choose Add to Map > MPLS-TP Tunnel.
•
In the main toolbar, click Add to Map, then choose Add to Map > MPLS-TP Tunnel.
The Add MPLS-TP Tunnel 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 MPLS-TP tunnels or a specific MPLS-TP tunnel. Search categories include:
–
Description
–
Name
–
System Name
•
Choose Show All to display all the MPLS-TP tunnels.
Step 4
Select the MPLS-TP tunnel that you want to add to the map.
Step 5
Click OK.
The MPLS-TP tunnel is added to the map and to the navigation pane.
In Figure 17-1:
•
The devices are on the left side of the map, and the MPLS-TP tunnel is displayed in a thumbnail on the right.
•
The devices are connected to each other and to the MPLS-TP tunnel via tunnels.
•
Physical links connect the devices to the Working and Protected LSPs.
•
A redundancy service badge is displayed next to the Protected LSP in the navigation and map panes.
•
In the thumbnail:
–
The tunnel endpoints are connected to each other via a tunnel.
–
A physical link connects the Working and Protected LSPs.
–
Business links connect the Working and Protected LSPs to each endpoint.
Figure 17-1 MPLS-TP Tunnel in Prime Network Vision Map
If an LSP is in lockout state, it is displayed with the lock badge (
).
By expanding all aggregations in the MPLS-TP tunnel (see Figure 17-2), you can see components and links in the MPLS-TP tunnel, including:
•
MPLS-TP tunnel endpoints
•
LSP endpoints
•
LSP midpoints
Figure 17-2 MPLS-TP Tunnel Expanded
If an LSP is configured for redundancy service, a redundancy service badge is applied to the secondary (backup) LSP in the navigation and map panes in the navigation and map panes.
For more information about LSP redundancy service, see Viewing LSP Endpoint Redundancy Service Properties.
Viewing MPLS-TP Tunnel Properties
Prime Network Vision discovers and displays MPLS-TP attributes in the MPLS-TP branch in logical inventory as described in this topic.
Additional information about MPLS-TP tunnel properties are available in the following branches:
•
Routing Entities—See Viewing Routing Entities.

Applying an MPLS-TP Tunnel Overlay
You can select and display an overlay of a specific MPLS-TP tunnel 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 an MPLS-TP tunnel is selected in the map, the following elements are highlighted in the map:
•
Elements on which TP endpoints and LSPs are configured.
•
Links that carry TP traffic.
All elements and links that are not part of the MPLS-TP tunnel are dimmed.
To apply an MPLS-TP tunnel overlay:
Step 1
In Prime Network Vision, display the network map on which you want to apply an overlay.
Step 2
From the main toolbar, click Choose Overlay Type and choose MPLS-TP tunnel.
The Select MPLS-TP tunnel 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 MPLS-TP tunnels or a specific MPLS-TP tunnel. Search categories include:
–
Description
–
Name
–
System Name
The search condition is "contains." Search strings are case-insensitive. For example, if you choose the Name category and enter "net," Prime Network Vision displays MPLS-TP tunnels that have "net" in their names whether net appears at the beginning of the name, the middle, or at the end: for example, Ethernet.
•
Choose Show All to display all MPLS-TP tunnels.
Step 4
Select the MPLS-TP tunnel overlay you want to apply to the map.
The elements and links used by the selected MPLS-TP tunnel are highlighted in the network map, and the MPLS-TP tunnel name is displayed in the window title bar as shown in Figure 17-10.
Figure 17-10 MPLS-TP Tunnel Overlay
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 VPNs
The following topics describe:
•
Creating a VPN
•
Adding a VPN to a Map
•
Removing a VPN from a Map
•
Moving a Virtual Router Between VPNs
Creating a VPN
You can change business configurations by manually creating VPNs. The VPNs that are manually created do not contain virtual routers and sites.
To create a VPN:
Step 1
In the Prime Network Vision navigation pane, select the map root.
Step 2
From the File menu, choose Add to Map > VPN > New.
Step 3
In the Create VPN dialog box, enter the following:
•
Name—A unique name for the new VPN.
Note
VPN business element names are case sensitive.
•
Icon—To use a custom icon for the VPN, click the button next to the Icon field and navigate to the icon file.
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 Vision 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 Prime Network Vision, 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," Prime Network Vision displays VPNs that have "net" in their names whether at the beginning of the name, the middle, or the end.
•
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 Prime Network Vision window content pane. In addition, any tickets are displayed in the ticket area.
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 Vision 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 Prime Network Vision 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 Prime Network Vision 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.
Working with VPN Overlays
The following topics describe:
•
Applying VPN Overlays
•
Managing a VPN Overlay Display in the Map View
•
Displaying VPN Callouts in a VPN Overlay
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 Prime Network Vision, 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," Prime Network Vision displays VPNs that have "net" in their names whether net appears at the beginning of the name, the middle, or at the end: 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 17-13) enable you to view the VPN traffic links for a specific link (either bidirectional or unidirectional).
Note
The link must be displayed in the VPN overlay and not dimmed for you to display the link callouts.

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 Prime Network Vision.
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.

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 Neighbors—Details all MPLS interface peers that use the Label Distribution Protocol (LDP). LDP enables neighboring 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
