Page 193: Stp/Rstp Overview
Huawei AR3200 Series Enterprise Routers Configuration Guide - LAN 7 STP/RSTP Configuration 7.1 STP/RSTP Overview STP/RSTP is used to block redundant links on Layer 2 networks and trim a network into a loop- free tree topology. Background Network designers tend to deploy multiple physical links between two devices (one link is the master and the others are backups) to fulfill network redundancy requirements.
Page 194 Huawei AR3200 Series Enterprise Routers Configuration Guide - LAN 7 STP/RSTP Configuration STP port roles – Root port The root port is the port that is nearest to the root bridge. The root port is determined based on the path cost. Among all the STP-capable ports on the network bridge, the port with the lowest root path cost is the root port.
Page 195 Huawei AR3200 Series Enterprise Routers Configuration Guide - LAN 7 STP/RSTP Configuration As shown in Figure 7-1, RSTP defines four port roles: root port, designated port, alternate port, and backup port. The functions of the root port and designated port are the same as those defined in STP.
Page 196 A port in the Discarding state can only receive BPDUs. CAUTION MSTP is the default mode for all Huawei datacom devices. After a device experiences the transition from the MSTP mode to the STP mode, an STP-capable port supports the same port states as those supported by an MSTP-capable port, including the Forwarding, Learning, and Discarding states.

To address this problem, enable the digest snooping function on the Huawei device. Context Perform the following steps on a switching device in an MST region to enable the digest snooping function.
Page 265: Checking The Configuration
The digest snooping function is enabled. ----End 8.6.5 Checking the Configuration After MSTP parameters are configured for the interoperability between Huawei devices and non-Huawei devices, you can verify the configurations. Prerequisites All the configurations for the interoperability between Huawei devices and non-Huawei devices are complete.

Page 267 Huawei AR3200 Series Enterprise Routers Configuration Guide - LAN 8 MSTP Configuration Loops will cause broadcast storms, thereby exhausting network resources and paralyzing the network. Loops also cause flapping of MAC address tables and damages MAC address entries. MSTP can be deployed to eliminate loops. MSTP blocks redundant links on a Layer 2 network and trims the network into a loop-free tree.
