STP and RSTP Configuration

The Spanning Tree Protocol (STP) 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. The Rapid Spanning Tree Protocol (RSTP) develops rapid convergence and introduces the edge port and its protection function based on STP.

Overview of STP/RSTP: STP/Rapid Spanning Tree Protocol (RSTP) is used to block redundant links on the Layer 2 network and trim a network into a loop-free tree topology.

Configuration Precautions for STP and RSTP

Configuring Basic STP/RSTP Functions: STP/Rapid Spanning Tree Protocol (RSTP) is used to block redundant links on the Layer 2 network and trim a network into a loop-free tree topology.

Configuring STP/RSTP Parameters on an Interface: A feedback mechanism is provided to confirm topology convergence. Thus, rapid convergence is implemented for Rapid Spanning Tree Protocol (RSTP).

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

Configuring STP/RSTP Interoperability Between Huawei Devices and Non-Huawei Devices: To support STP/Rapid Spanning Tree Protocol (RSTP) interoperability between Huawei devices and non-Huawei devices, proper parameters are required on Huawei devices running STP/RSTP to ensure nonstop communication.

Maintaining STP/RSTP: STP/Rapid Spanning Tree Protocol (RSTP) maintenance includes resetting STP/RSTP statistics.

Configuration Examples for STP/RSTP: This section shows typical usage scenarios of STP/Rapid Spanning Tree Protocol (RSTP) by describing networking requirements, configuration roadmap, and data preparation, and provides related configuration files.
