17-6 Cisco Prime Network 4.3.2 User Guide Chapter 17 Managing MPLS Networks Working with MPLS-TP Tunnels 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 Vision client 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 the Vision client: Adding an MPLS-TP Tunnel, page 17-7 Viewing MPLS-TP Tunnel Properties, page 17-9 Viewing LSPs Configured on an Ethernet Link, page 17-13 Viewing LSP Endpoint Redundancy Service Properties, page 17-15 Applying an MPLS-TP Tunnel Overlay, page 17-17 Viewing BFD Session Properties, page 17-50.
17-7 Cisco Prime Network 4.3.2 User Guide Chapter 17 Managing MPLS Networks Working with MPLS-TP Tunnels Adding an MPLS-TP Tunnel Prime Network 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 1In the Vision client, display the map to which you want to add the MPLS-TP tunnel. Step 2Do 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 3Do 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 4Select the MPLS-TP tunnel that you want to add to the map. Step 5Click OK. The MPLS-TP tunnel is added to the map and to the navigation pane. In Figure 17-3: 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.
