Adding an Interface to an MSTP Process - Share Link

Adding an Interface to an MSTP Process - Share Link

The link shared by multiple access rings is called a share link. The interfaces on the share link need to participate in Multiple Spanning Tree Protocol (MSTP) calculation in multiple access rings in different MSTP processes. After being added to MSTP processes, interfaces on the access links can participate in MSTP calculation.

Context

Do as follows on the devices connected to access rings:

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The view of the Ethernet interface participating in STP calculation is displayed.

    The interface specified in this command must be an interface on the share link between the devices configured with MSTP multi-process but not the interfaces that connect an access ring and a device.

    NOTE:
    The following configuration can be configured both on a Layer 2 interface and a Layer 3 interface.

  3. Run stp binding process process-id [ to process-id ] link-share

    The interface is added to multiple MSTP processes to complete MSTP calculation.

    NOTE:

    For a process with share links, you must run the stp enable command globally. For an interface that is added to the process in link-share mode, you must run the stp enable command in the interface view.

  4. Run commit

    The configuration is committed.
