Summary of MSTP Configuration Tasks

Summary of MSTP Configuration Tasks

Before configuring Multiple Spanning Tree Protocol (MSTP), familiarize yourself with the concepts of basic MSTP functions, topology convergence, MSTP protection, MSTP multi-process, and MSTP interoperability between Huawei devices and non-Huawei devices. This will help you complete the configuration task quickly and accurately.

MSTP is used to block redundant links on the Layer 2 network and trim a network into a loop-free tree. In MSTP, multiple MSTIs can be created and VLANs are mapped into different instances to load-balance VLAN traffic. The basic configuration roadmap of MSTP is as follows:

  1. In a ring network, divide regions and create different instances for regions.

  2. Select a switching device functioning as a root bridge from switching devices for each instance.

  3. In each instance, calculate the shortest paths from the other switching devices to the root bridge, and select a root port for each non-root switching device.

  4. In each instance, select a designated port for each connection according to port IDs.
