Exampling for Configuring a Hard-Pipe Static SS-PW

This section provides an example for configuring a hard-pipe static SS-PW to carry a leased line service.

Networking Requirements

IP hard pipe is a pipe technology that establishes a static PW over a static bidirectional co-routed LSP to simulate an SDH leased line.

In an IP hard pipe scenario, hard pipe needs to be configured for PWs on the public network side. On the network shown in Figure 1, an SVC needs to be set up between CE1 and CE2. The SVC needs to be created on PEs with specified VC labels.

Figure 1 Hard-pipe static SS-PW networking

  • Interfaces 1 and 2 in this example represent GE 0/1/0 and GE 0/1/8, respectively.



Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure an IGP on the MPLS backbone network to ensure IP connectivity.

  2. Enable MPLS and MPLS L2VPN.

  3. Create a static L2VC connection between PEs and manually configure VC label information.

  4. Configuring Interface-based Hard Pipe Bandwidth Reservation.

Data Preparation

To complete the configuration, you need the in-label and out-label of the static L2VC connection.

The out-label of PE1 is the same as the in-label of PE2, and the in-label of PE1 is the same as the out-label of PE2.

Procedure

  1. Assign IP addresses to interfaces on the CEs, PEs, and P as shown in Figure 1.
  2. Configure an IGP (OSPF in this example) on the MPLS backbone network.
  3. Configure basic MPLS functions on the MPLS backbone network.

  5. Configure the ingress, transit node, and egress for a static bidirectional co-routed LSP.

    # Configure PE1 as the ingress.

    [~PE1] bidirectional static-cr-lsp ingress Tunnel10

[*PE2-bi-static-egress-lsp1] hard-pipe enable
[*PE2-bi-static-egress-lsp1] quit
[*PE2] commit

  6. Configure a reverse tunnel attribute on the tunnel interface of PE2 and bind the tunnel interface to the static bidirectional co-routed LSP.

    [~PE2] interface Tunnel20
[~PE2-Tunnel20] mpls te passive-tunnel
[*PE2-Tunnel20] mpls te binding bidirectional static-cr-lsp egress lsp1
[*PE2-Tunnel20] quit

  7. Enable MPLS L2VPN on the PEs and create a static L2VC connection.

    # Create a VC on GE0/1/0 that connects PE1 to CE1.

    [~PE1] mpls l2vpn
[*PE1-l2vpn] quit
[~PE1] tunnel-policy policy1

  8. Configuring Interface-based Hard Pipe Bandwidth Reservation.

    # Configure PE1.

    [*PE1] interface gigabitethernet 0/1/8
[*PE1-GigabitEthernet0/1/8] qos hard-pipe share-mode bandwidth 500 outbound
[*PE1] commit

    # Configure the P.

    [*P] interface gigabitethernet 0/1/0

[*P] interface gigabitethernet 0/1/8
[*P-GigabitEthernet0/1/8] qos hard-pipe share-mode bandwidth 500 outbound

    # Configure PE2.

[*PE2] commit

  9. Verify the configuration.

    Run the display mpls static-l2vc hard-pipe command on each PE to check hard-pipe VPWS information. The command output shows that a static L2VC has been set up. The following example uses the command output on PE1.
