(Optional) Disabling LDP LSP Flapping Suppression

LDP LSP flapping suppression helps effectively prevent label flapping. This function can be disabled.

Context

After an LDP LSP goes Up, it goes Down due to a protocol or interface failure. A device attempts to reestablish the LDP LSP, which maximizes the LDP LSP protocol hard convergence. If LDP LSP alternates between Up and Down when a downstream node frequently sends a label to an upstream node or a label is withdrawn, CPU usage increases. To prevent label suppression, configure LDP LSP flapping suppression.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run mpls

    The MPLS view is displayed.

  3. Run mpls ldp

    MPLS LDP has been enabled globally.

  4. Run protocol-packets suppress disable

    LDP LSP flapping suppression is disabled.

  5. Run commit

    The configuration is committed.
