Configuring Shared-Link Protection on a Switch

Context

Shared-link protection is used in scenarios where a switch is dual homed to a network.

If a shared link fails, shared-link protection forcibly changes the working mode of a local switch to RSTP. This function can be used together with root protection to avoid network loops.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run stp process process-id

    The MSTP process view is displayed.

    NOTE:

    Skip this step if you perform configurations in the MSTP process 0.

  3. Run stp link-share-protection

    Shared-link protection is enabled.
