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:

  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.

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 17-4), you can see components and 
links in the MPLS-TP tunnel, including: 
MPLS-TP tunnel endpoints
LSP endpoints
LSP midpoints
