(Optional) Configuring Global Dynamic Bandwidth Pre-verification

(Optional) Configuring Global Dynamic Bandwidth Pre-verification

Global dynamic bandwidth pre-verification enables a device to check dynamic bandwidth usage before a static CR-LSP, or a static bidirectional co-routed LSP is established.


When dynamic services or both static and dynamic services are configured, a device only checks static bandwidth usage when a static CR-LSP or a static bidirectional co-routed LSP is configured. The configuration is successful even if the interface bandwidth is insufficient, and the interface status is Down. To percent such an issue, global dynamic bandwidth pre-verification can be configured. With this function enable, the device can prompt a message indicating that the configuration fails in the preceding situation.

    The system view is displayed.

  2. Run:


    MPLS is enabled globally, and the MPLS view is displayed.

  3. Run:

    mpls te

    MPLS TE is enabled globally.

    Global dynamic bandwidth pre-verification can only be configured after MPLS TE is enabled globally.

  4. Run:

    mpls te static-cr-lsp bandwidth-check deduct-rsvp-bandwidth

    Global dynamic bandwidth pre-verification is enabled.
