Example for Configuring the PWE3 Trace Test on a Multi-Hop PW

Networking Requirements

In Figure 1, CE-A and CE-B are respectively connected to U-PE1 and U-PE2 through VLAN. U-PE1 and U-PE2 are connected through the MPLS backbone network. The LSP needs to be used and S-PE is set as the switching node to set up a dynamic multi-hop PW between U-PE1 and U-PE2.

The PWE3 Trace function of the multi-hop PW needs to be performed to test the connectivity of the PW between U-PE1 and U-PE2.

Figure 1 Networking diagram for configuring the PWE3 Trace test on a multi-hop PW

Configuration Roadmap

The configuration roadmap is as follows:

  1. Run the IGP protocol on the backbone network to make the routes between Switches on the backbone network reachable.

  2. Configure the basic MPLS functions on the backbone network and set up an LSP tunnel. Set up MPLS LDP peer relations between U-PE1 and S-PE, and between U-PE2 and S-PE.

  3. Create an MPLS L2VC connection between the two U-PEs.

  4. Create a switching PW on the switching node S-PE.

  5. Configure a PWE3 Trace test on the multi-hop PW on U-PE1.

Procedure

  1. Configure a dynamic multi-hop PW.

    Configure a dynamic multi-hop PW on the MPLS backbone network. For the detailed configuration procedure, see PWE3 Configuration in the S2720, S5700, and S6700 V200R019C10 Configuration Guide - VPN.

  2. Configure a PWE3 Trace test of the multi-hop PW.

    # Configure U-PE1.

    <HUAWEI> system-view
[HUAWEI] sysname U-PE1
[U-PE1] nqa test-instance test pwe3trace
[U-PE1-nqa-test-pwe3trace] test-type pwe3trace
[U-PE1-nqa-test-pwe3trace] local-pw-id 100
[U-PE1-nqa-test-pwe3trace] local-pw-type vlan
[U-PE1-nqa-test-pwe3trace] label-type control-word
[U-PE1-nqa-test-pwe3trace] remote-pw-id 200

  3. Perform the test.

    [U-PE1-nqa-test-pwe3trace] start now

  4. Verify the test result.

    After running the display nqa history command on the PE device, you can see that the status is successful.

    Running the display nqa results command on the PE device, you can see that the test is successful.
