Example for Configuring a Dynamic VPWS SS-PW over SRv6 TE Policy (Manual Configuration)

This section provides an example for configuring a dynamic VPWS SS-PW over an SRv6 TE Policy.

Networking Requirements

On the network shown in Figure 1, PE1, the P, and PE2 are in the same AS and run IS-IS to implement IPv6 network connectivity. It is required that a bidirectional SRv6 TE Policy be deployed between PE1 and PE2 to carry VPWS PWs.

Figure 1 Configuring a dynamic VPWS SS-PW over an SRv6 TE Policy
  • In this example, interfaces 1 and 2 represent GE 0/1/0 and GE 0/1/8, respectively.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Enable IPv6 forwarding and configure an IPv6 address for each interface on PE1, the P, and PE2.

  2. Enable IS-IS, configure an IS-IS level, and specify a network entity title (NET) on PE1, the P, and PE2.

  3. Configure SRv6 SIDs and enable IS-IS SRv6 on PE1, the P, and PE2.

  4. Deploy an SRv6 TE Policy between PE1 and PE2.

  5. Set up LDP sessions between PEs.
  6. Enable MPLS L2VPN on PEs and establish a VPWS PW.

Data Preparation

To complete the configuration, you need the following data:

  • IPv6 address of each interface on PE1, the P, and PE2

  • IS-IS process ID of PE1, the P, and PE2

  • IS-IS level of PE1, the P, and PE2

Procedure

  1. Enable IPv6 forwarding and configure an IPv6 address for each interface.

    # Configure PE1. The configurations of the P and PE2 are similar to the configuration of PE1. For configuration details, see Configuration Files in this section.

    Configure an IPv4 address for the loopback interface, as the L2VPN source address needs to be an IPv4 address.

  2. Configure IS-IS.

    # Configure PE1.

    After the configuration is complete, perform the following operations to verify the IS-IS configuration:

    # Display IS-IS neighbor information. The following example uses the command output on PE1.

    [~PE1] display isis peer
                          Peer information for ISIS(1)

    After the configuration is complete, run the display segment-routing ipv6 locator [ locator-name ] verbose command to check SRv6 locator information.

    The following example uses the configuration on PE1.

    [~PE1] display segment-routing ipv6 locator verbose

  5. Establish an LDP session.

    Establish a remote session between PE1 and PE2.

    # Configure PE1.

    [~PE1] mpls ldp
[*PE1-mpls-ldp] quit
[*PE1] mpls ldp remote-peer 3.3.3.3

[*PE2-mpls-ldp-remote-1.1.1.1] commit

    After the configuration is complete, an LDP session is successfully set up between the PEs.

    The following example uses the command output on PE1.

    [~PE1] display mpls ldp session

    • The VC IDs at the two ends of the VPWS PW to be established must be the same. Otherwise, the PW cannot go up.

    • No IP address needs to be configured on the PE interfaces connecting to CEs.

  7. Verify the configuration.

    View VPWS PW information on PEs. The command output shows that a VC has been established and its status is up.

    The following example uses the command output on PE1.

    <PE1> display mpls l2vc interface gigabitethernet 0/1/8
