Describes how to run the RSVP-TE optimization tool to improve LSP routing and bandwidth allocation in your network.

Use this task optimize RSVP-TE LSPs and interfaces to enhance routing and ensure bandwidth requirements are met.

Before you begin

  • If this is the first time using the tool and if you want to use your own preconfigured RSVPTEOpt properties, you must manually edit the LSPs and Interfaces tables to create them:

    • LSP RSVPTEOpt::Group: Place LSPs into the Opt, Fit, or Fix groups. Any remaining LSPs are placed in the Ignore group.

    • LSP RSVPTEOpt::RequiredBW: Define an exact amount for the sum total of LSP bandwidth that is using the interface.

    • Interface RSVPTEOpt::BWBound: Define an exact amount of bandwidth that the interface can hold.

    • Interface RSVPTEOpt::Metric: Define an exact amount to use in shortest path calculations.

  • If you are creating disjoint paths between LSPs in the same disjoint group, you must first add the LSPs to the disjoint groups in the Edit LSPs page. Here, you can also assign priorities to LSPs within these groups. Higher priority LSPs are assigned shorter routes based on the metric being used for shortest path calculations. The higher the number, the lower the priority.

Procedure

  1. Open the plan file (refer to Open plan files). It opens in the Network Design page.

  2. From the toolbar, choose Actions > Tools > RSVP LSP optimization > RSVP-TE optimization.

    Alternatively, choose Preset workflows > Perform optimization, select RSVP LSP Optimization as the optimization type, select RSVP-TE optimization from the drop-down list, and click Launch.

  3. In the Specify LSP groups section, make selections for optimizing LSPs based on Opt, Fit, or Fix LSP groups, or based on those defined in the RSVPTEOpt::Group property. For more information, refer to LSP group options.

  4. Expand the LSP parameters panel. In the Required BW field, set bandwidth requirements for the primary LSP paths. For more information, refer to Optimization parameters.

  5. Expand the Interface parameters panel. In the BW bound field, set how much bandwidth the interfaces can carry. In the Metric field, specify on which property to base the shortest path. For more information, refer to Optimization parameters.

  6. Click Next.

  7. On the Run Settings page, choose whether to execute the task now or schedule it for a later time. Choose one of these Execute options:

    • Now: Choose this option to execute the job immediately. The tool runs and changes are applied to the network model immediately. A summary report appears. You can access the report any time later using Actions > Reports > Generated reports option.

    • As a scheduled job: Choose this option to execute the task as an asynchronous job. Set these options:

      • Priority: Select the priority of the task.

      • Engine profiles: Select the engine profile as needed. This section lists all the available asynchronous engine profiles.

      • Schedule: Set the time at which you want to run the tool.

      The tool runs at the scheduled time using the selected engine profile. You can track the status of the job at any time using the Job Manager page (from the main menu, choose Job Manager). Once the job completes, import the output plan file into user space to visualize it. For more information, refer to Access output plan files from job manager.

      Note
      Ensure that you save the plan file before you schedule the job. Any unsaved changes in the plan file are not considered when you run the tool as a scheduled job.

  8. (Optional) If you want to display the result in a new plan file, specify a name for the new plan file in the Display results section.

    In the previous step:

    • If you have selected to run the task immediately, by default, the changes are applied on the current plan file. If you want to display the results in a new file, select the Display results in a new plan file check box and enter the name of the new plan file.

    • If you have scheduled the task to run at a later time, by default, the results are displayed in the Plan-file-1. Update the name, if required.

  9. Submit your changes.
