(Optional) Configuring Auto Bypass Tunnel Re-Optimization

(Optional) Configuring Auto Bypass Tunnel Re-Optimization

Auto Bypass tunnel re-optimization allows paths to be recalculated at certain intervals for an auto bypass tunnel. If an optimal path is recalculated, a new auto bypass tunnel will be set up over this optimal path. In this manner, network resources are optimized.

Context

Network changes often cause the changes in optimal paths. Auto bypass tunnel re-optimization allows the system to re-optimize an auto bypass tunnel if an optimal path to the same destination is found due to some reasons, such as the changes in the cost. In this manner, network resources are optimized.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    mpls

    The MPLS view is displayed.

  3. Run:

    mpls te auto-frr reoptimization [ frequency interval ]

    Auto bypass tunnel re-optimization is enabled.

  4. (Optional) Run:

    return

    Return to the user view.

  5. (Optional) Run:

    mpls te reoptimization [ auto-tunnel name tunnel-interface | tunnel tunnel-number ]

    Manual re-optimization is enabled.

    After you configure the automatic re-optimization in the MPLS view, you can return to the user view and run the mpls te reoptimization command to immediately re-optimize the tunnels on which the automatic re-optimization is enabled. After you perform the manual re-optimization, the timer of the automatic re-optimization is reset and counts again.

  6. Run:

    commit

    The configurations are committed.
