To configure a dynamic MS-PW service using PW routing

Steps
 

Choose Manage→Service→Services from the NFM-P main menu. The Manage Services form opens.


Configure the filter criteria for Service→VLL (VLL)→Epipe Service→(Epipe). A list of services appears at the bottom of the Manage Services form.


Choose the required VLL Epipe service that contains the T-PE site and click Properties. The Epipe Service (Edit) form opens.


Click on the Spoke SDP FECs tab.


Click Create. The Spoke SDP FEC (Create) form opens.

Only one spoke can be configured on the terminating site, including both regular spoke SDP bindings and spoke SDP FECs.


Configure the required parameters.

The Auto Config parameter enables automatic endpoint configuration. This allows the configuration of a spoke SDP endpoint without specifying the TAII associated with that spoke SDP. In this mode, the far end T-PE actively initiates MS-PW signaling and will send the initial label mapping message using T-LDP, while the T-PE for which Auto Config is specified will act as the passive T-PE. The Auto Config parameter cannot be enabled if the Signaling Type is set to Master or if the TAII Address is specified.

If you are going to use SAII and TAII addresses instead of Auto Config, then you must decide which method will be used for the PW routing.

  • For dynamic PW routing, the local prefix associated with the SAII/TAIl address should be configured with a route distinguisher, with an optional community (see To configure PW routing on an NE ). The SAII and TAII addresses must be unique in the network.

  • For static routing, the local prefix should be associated with static routes configured under PW routing (see Step 5 and Step 6 in To configure PW routing on an NE ). A spoke SDP FEC cannot be turned up if no local prefix is configured under PW routing.

  • When using a specified path, the Path parameter must be configured. The associated Select button allows you to select a path that will be used for this spoke SDP and which is configured under PW Routing. If no path is configured, then each next hop of the MS-PW used by the spoke SDP will be chosen locally at each S-PE and T-PE, using dynamic PW routing.


If redundancy is required, select an Endpoint.


Configure the required parameters.


To configure a return spoke SDP FEC:

  1. Click on the Return Spoke SDP FEC tab.

    This tab is displayed only when the TAII Address configured in Step 6 was set by selection for the current spoke SDP FEC.

  2. Configure the PW ID parameter for the return spoke SDP FEC and click Apply.

    When a valid PW ID for the return spoke SDP FEC is entered, additional parameters are displayed. If the PW ID is not valid, then the return spoke SDP FEC is not created.

  3. Configure the required parameters.

  4. Select an Endpoint.

    When the return spoke SDP FEC is created, it will have corresponding attributes such as the SAII and TAII Address values and AC ID cross-matching with the current spoke SDP FEC.

Save the changes and close the forms.

When a spoke SDP FEC is successfully created, it will be listed under the Spoke SDP FECs tab for this Epipe site.

The Spoke SDP Associated tab lists the spoke SDP bindings created by using this Spoke SDP FEC for MS-PW routing. All such spoke SDP bindings have their Creation Mode attribute set as Multi-Segment PW. The related SDP FEC Auto-bind tab shows the associated SAII or TAII defined in the Spoke SDP FEC.

The Faults tab displays any mis-configuration alarms associated with this spoke SDP FEC.

When the configuration for both T-PEs is complete, the NEs can start negotiating and establishing the spoke SDP bindings from T-PE to S-PE and from S-PE to T-PE.
