To create a bidirectional MPLS-TP LSP
Purpose
A bidirectional LSP consists of MPLS-TP LSPs or LER LSPs that are created on the edge NEs, and the LSR cross-connect—or transit path—that is created on the transit NEs. The NFM-P guides you through the creation of the bidirectional MPLS-TP LSP. When the Apply or OK button is disabled, verify that all necessary parameters are configured. When all possible parameters are configured, the NFM-P displays a Hint button to provide instructions on the necessary actions.
This procedure requires the existence of a numbered or unnumbered L3 network interface on the NE that hosts the MPLS-TP instance. See NE routing and forwarding for more information about how to configure network interfaces.
Note: NFM-P guided provisioning is available only for the creation of bidirectional MPLS-TP LSPs. The Hint button does not appear if you are configuring an existing bidirectional MPLS-TP LSP.
Steps
1 |
Choose Manage→MPLS→MPLS-TP LSPs from the NFM-P main menu. The Manage MPLS-TP LSPs form opens. |
2 |
Click Create and choose Create Bidirectional TP-LSP. The Bidirectional TP-LSP (Create) form opens. |
3 |
Configure the required parameters. The TP-LSP ID must be in the range of the TP-LSP ID Minimum and TP-LSP ID Maximum parameters that you specified in Step 3 of To configure MPLS-TP on a routing instance . |
4 |
Click Select in the LER A panel and choose a source site and click OK. |
5 |
Click Select in the LER B panel and choose a source site and click OK. |
6 |
Click on the LSP Path tab and click Create. The Bidirectional TP-LSP Path (Create) form opens. |
7 |
Configure the required parameters Note: You can create one working path and one protecting path per LSP. As required, repeat Step 6 to Step 17 to create the alternate path type. The LSP Path Number parameter is a global LSP path number that configures the LSP path number on the LER A working and protecting paths, the LER B working and protecting paths, and on the LSR static hop.The LSP Path Number parameter must be the same on all of the hops. |
8 |
Click on the LER A tab and click Select. The Select Out-Link - Bidirectional TP-LSP Path list form opens. |
9 |
Choose a site and click OK. |
10 |
Click on the Hint button. A window appears displaying an instructional message. |
11 |
Perform one of the following:
|
12 |
Create an LSR path hop: Perform the following steps:
|
13 |
Click on the Hint button. Perform one of the following based on the message returned:
|
14 |
Click on the LER B tab. |
15 |
Click Select in the Out-Link panel and choose an interface and click OK. See To create an MPLS interface for information about how to configure MPLS interfaces. |
16 |
Click on the Hint button. The message “You have configured the LER-B Out-Link Interface. As a result, NFM-P has auto-completed the data between LER-B and its next hop on the forward path. The path configuration is now complete.” appears, click OK to complete the path configuration. |
17 |
Save your change and close the forms. |
18 |
Create a BFD template on the LER A and LER B. See To configure a BFD template policy . |
19 |
Create a proactive OAM template on the LER A and LER B. See To configure MPLS-TP on a routing instance . End of steps |
