Example for Configuring LSP Jitter Test for a TE Tunnel

Networking Requirements

In Figure 1:

  • The OSPF protocol runs on SwitchA, SwitchB, and SwitchC. They have learned the 32-bit host routes of each other on their loopback interfaces.

  • MPLS, MPLS TE, and MPLS RSVP-TE are enabled on SwitchA, SwitchB, and SwitchC.

  • MPLS, MPLS TE, and MPLS RSVP-TE are enabled on the VLANIF interfaces on SwitchA, SwitchB, and SwitchC to set up a TE tunnel from SwitchA to SwitchC.

An NQA LSP Jitter test needs to be performed for the TE tunnel.

Figure 1 Networking diagram for configuring the LSP Jitter test

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure SwitchA as the NQA client and create an LSP Jitter test instance on SwitchA.

  2. Configure SwitchC as the NQA server.

Procedure

  1. Configure SwitchA, SwitchB, and SwitchC and run OSPF to implement reachable routes between them.

  3. View the status of the TE tunnel.

    The display on SwitchA is used as an example.

  4. Create an NQA test instance on SwitchA.

    # Enable the NQA client and create an LSP Jitter test instance for the TE tunnel.

    [SwitchA] nqa test-instance admin lspjitter
[SwitchA-nqa-admin-lspjitter] test-type lspjitter

  5. Start the test instance. 

    [SwitchA-nqa-admin-lspjitter] start now

  6. Verify the test result.

    # When the network runs stably, verify the test result.

    [SwitchA-nqa-admin-lspjitter] display nqa results test-instance admin lspjitter
