Configuring an MPLS Tunnel

Configuring an MPLS Tunnel

On a PSN network, the MPLS tunnel carries PWs where various services are encapsulated. In this manner, data packets can be transparently transmitted between NEs. One MPLS tunnel can carry several PWs. Before configuring a service, you need to configure the MPLS tunnel that carries the service. On the NMS, you can use the per-NE configuration scheme to configure an MPLS tunnel.

Context

NOTE:
Before configuring MPLS tunnels, you need to plan MPLS tunnels according to the description of MPLS tunnel numbers in "Functions and Features" of Hardware Description.

Configuring LSR ID

In the Basic Configuration interface, you can set LSR (Label Switch Router) ID.

Prerequisites

You are an NM user with Administrators rights or higher.

Procedure

  1. In the NE Explorer, select the NE and choose Configuration > Packet Configuration > MPLS Management > Basic Configuration from the Function Tree.
  2. Set LSR ID.

    For details about LSR ID, see Basic Configuration.

    NOTE:
    • When the LSR ID is specified for the first time, a warm-reset occurs on the NE but does not affect services. If the specified LSR ID is then changed, no warm-reset occurs on the NE and services are not affected.
    • If a tunnel exists, do not change the LSR ID.

Configuring an MPLS Tunnel in an End-to-End Mode

This topic describes how to configure an MPLS tunnel in end-to-end mode by using the NMS.

Configuring a Unidirectional MPLS Tunnel

When creating a unidirectional MPLS tunnel in end-to-end mode, you select the source NE, sink NE, or transit NE directly in the physical topology and then complete creation of the unidirectional MPLS tunnel on the NMS.

Prerequisites

Procedure

  1. Choose Service > Tunnel > Create Tunnel from the Main Menu. Then, the Create Tunnel window is displayed.
  2. Set the basic information about the MPLS tunnel. For details about the parameters, see the Parameters for Configuring a Static Tunnel (in End-to-End Mode).



    • Protocol Type: MPLS
    • Signaling Type: Static CR
    • Select Create Reverse Tunnel.

  3. Set the information in NE List of the MPLS tunnel. For details about the parameters, see the Parameters for Configuring a Static Tunnel (in End-to-End Mode).

    1. Select the source NE, sink NE, and transit NE, and adjust the position of the NE on the entire MPLS tunnel.

      Three methods can be used to select the source, sink, and transit NEs:
      • Method 1: In Physical Topology at the upper right, right-click an NE and choose Add.
      • Method 2: In Physical Topology at the upper right, double-click an NE.
      • Method 3:
        1. Click the Add button and then choose NE from the drop-down menu.
        2. Select an NE from the window that is displayed and then click OK.
      NOTE:
      • You can specify the position of an NE on the entire tunnel by setting NE Role or adjust the position of an NE on the entire tunnel by clicking Up or Down.

      • Select Deploy to deliver the tunnel configuration data to the NEs.

  4. Set CIR and PIR for the NEs on the MPLS tunnel.

  5. Click the Details button and set the information about the tunnel. For details about the parameters, see the Parameters for Configuring a Static Tunnel (in End-to-End Mode).

    NOTE:
    • Click Auto-Assign following the Tunnel ID field box. Then, Tunnel ID is automatically allocated.
    • Click the blank cell under Outbound Interface/Ring of an Ingress node and then click . Select the output port of the ingress node in the list box that is displayed. Use the same method to select the input and output ports of the transit node and the input port of the egress node.
    • After the output port label is added at the ingress node and transit node, the next-hop address is generated automatically.
    • Click Auto-Assign Label at lower right of the window. Then, Outgoing Label of the ingress node, Outgoing Label and Incoming Label of the transit node, and Incoming Label of the egress node are allocated automatically.
    • After you set the parameters of the forward tunnel, the parameters of the reverse tunnel are generated automatically. Therefore, you need not set the parameters of the reverse tunnel manually.
    • Click Configure TP OAM(Y.1731) and configure MPLS-TP OAM parameters. Ensure that the OAM protocol version at the source and sink is Y.1731. Otherwise, the button will be grayed.
    • When the configured tunnel bandwidth is larger than the available bandwidth at a port, the NMS will reports an error. Therefore, plan and configure services based on the actual conditions.

  6. Click OK.
Configuring a Bidirectional MPLS Tunnel

When creating a bidirectional MPLS tunnel in end-to-end mode, select the source NE, sink NE, or transit NE directly in the physical topology and then complete creation of the bidirectional MPLS tunnel on the NMS.

Prerequisites

Procedure

  1. Choose Service > Tunnel > Create Tunnel from the Main Menu. Then, the Create Tunnel window is displayed.
  2. Set the basic information about the MPLS tunnel. For details about the parameters, see the Parameters for Configuring a Static Tunnel (in End-to-End Mode).



    • Protocol Type: MPLS
    • Signaling Type: Static CR
    • Service Direction: Bidirectional

  3. Set the information in NE List of the MPLS tunnel. For details about the parameters, see the Parameters for Configuring a Static Tunnel (in End-to-End Mode).

Configuring an MPLS Tunnel on a Per-NE Basis

This topic describes how to configure an MPLS tunnel on a per-NE basis by using the U2000.

Configuring a Unidirectional MPLS Tunnel

You can configure an end-to-end unicast MPLS tunnel on a per-NE basis. You need to configure the MPLS tunnel on each node that the MPLS tunnel traverses.

Prerequisites

Procedure

  1. In the NE Explorer, select the source NE of the MPLS tunnel and choose Configuration > Packet Configuration > MPLS Management > Unicast Tunnel Management from Function Tree.
  2. Click the Static Tunnel tab and click New > Unidirectional Tunnel. Then, the New Unicast Tunnel dialog box is displayed.
  3. Set the parameters of the forward and reverse MPLS tunnels. For details about the parameters, see Parameters for Configuring a Static Tunnel (on a Per-NE Basis).

    NOTE:
    • When Node Type is set to Egress, Bandwidth(kbit/s) is the same as the tunnel bandwidth in the Ingress direction and cannot be changed manually.
    • Set Next Hop Address to be the IP address of the port of the next node.
    • When the configured tunnel bandwidth is larger than the available bandwidth at a port, the NMS will reports an error. Therefore, plan and configure services based on the actual conditions.

  4. Click OK to complete the configuration of the static MPLS tunnel.
  5. Refer to steps 1-4 to configure the static MPLS tunnels on the intermediate NEs and sink NE.
