(Optional) Configuring a Protection Switching Trigger Mechanism


After configuring a tunnel protection group, you can configure a protection switching trigger mechanism to force traffic to switch to the primary LSP or the bypass LSP. Alternatively, you can perform switchover manually.

When configuring a protection switching trigger mechanism, note switch request criteria.

Perform the following steps on the ingress of the tunnel protection group.


  1. Run:


    The system view is displayed.

  2. Run:

    interface tunnel interface-number

    The tunnel interface view is displayed.

  3. Select one of the following protection switching trigger methods as required:

    • To forcibly switch traffic from the working tunnel to the protection tunnel, run:

      mpls te protect-switch force
    • To prevent traffic from switching on the working tunnel, run:

      mpls te protect-switch lock
    • To switch traffic to the protection tunnel, run:

      mpls te protect-switch manual
    • To clear the configuration of the protection switching trigger mechanism, run:
