MSTP Configuration

The Multiple Spanning Tree Protocol (MSTP) trims a ring network into a loop-free tree network. It prevents replication and circular propagation of packets, provides multiple redundant paths for Virtual LAN (VLAN) data traffic, and enables load balancing.

Overview of MSTP: The Multiple Spanning Tree Protocol (MSTP) incorporates the functions of the Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP), and outperforms them. It enables rapid convergence and provides load balancing across redundant paths.

Configuration Precautions for MSTP

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.

Configuring Basic MSTP Functions: Multiple Spanning Tree Protocol (MSTP) based on the basic STP/Rapid Spanning Tree Protocol (RSTP) function divides a switching network into multiple regions, each of which has multiple spanning trees that are independent of each other. MSTP isolates user traffic and service traffic, and load-balances VLAN traffic.

Configuring MSTP Multi-process: After a Multiple Spanning Tree Protocol (MSTP) device binds its ports to different processes, the MSTP device performs the MSTP calculation based on processes, and only relevant ports in each process take part in MSTP calculation.

Configuring MSTP Parameters on an Interface: Multiple Spanning Tree Protocol (MSTP) implements Rapid Spanning Tree Protocol (RSTP) rapid convergence. To achieve rapid convergence, you need to configure proper MSTP parameters.

Configuring MSTP Protection Functions: Multiple Spanning Tree Protocol (MSTP) protection functions are as follows, and you can configure one or more functions as required.

Configuring MSTP Interoperability Between Huawei Devices and Non-Huawei Devices: To enable Huawei devices to interwork with non-Huawei devices, configure proper parameters and functions, including the Bridge Protocol Data Unit (BPDU) format, Multiple Spanning Tree Protocol (MSTP) protocol packet format, and digest snooping function, on the Huawei devices running MSTP.

Maintaining MSTP: Multiple Spanning Tree Protocol (MSTP) maintenance includes resetting MSTP statistics.
