1) Network requirements
Device A connects to Device B, a third-party device that has different MSTP implementation. Both
devices are in the same region.
Device B is the regional root bridge, and Device A is the downstream device.

Configuring Protection Functions

An MSTP-enabled device supports the following protection functions:
BPDU guard
Root guard
Loop guard
TC-BPDU guard
BPDU dropping
Configuration prerequisites
MSTP has been correctly configured on the device.
Enabling BPDU guard
For access layer devices, the access ports generally connect directly with user terminals (such as PCs)
or file servers. In this case, the access ports are configured as edge ports to allow rapid transition. When
these ports receive configuration BPDUs, the system will automatically set these ports as non-edge
