Huawei AR3200 Series - 8 MSTP Configuration

8 MSTP Configuration
About This Chapter
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.
8.1 MSTP Introduction
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.
8.2 MSTP Features Supported by the AR3200
Before configuring MSTP, familiarize yourself with the concepts of basic MSTP functions,
topology convergence, MSTP protection, and MSTP interoperability between Huawei devices
and non-Huawei devices.
8.3 Configuring Basic MSTP Functions
MSTP based on the basic STP/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.
8.4 Configuring MSTP Parameters on an Interface
Proper MSTP parameter settings achieve rapid convergence.
8.5 Configuring MSTP Protection Functions
This section describes how to configure MSTP protection functions. You can configure one or
more functions.
8.6 Configuring MSTP Interoperability Between Huawei Devices and Non-Huawei Devices
To enable Huawei devices to work with non-Huawei devices on an MSTP-capable network,
configure the BPDU format, MSTP protocol packet format, and digest snooping function on the
Huawei devices.
8.7 Maintaining MSTP
MSTP maintenance includes clearing MSTP statistics.
