Implementation of MSTP on devices
MSTP is compatible with STP and RSTP. STP and RSTP protocol packets can be recognized by devices
running MSTP and used for spanning tree calculation.
In addition to basic MSTP functions, the following functions are provided for ease of management:
• Root bridge hold
• Root bridge backup
• Root guard
• BPDU guard
• Loop guard
• TC-BPDU guard
• BPDU drop
Protocols and standards
The spanning tree protocols are documented in the following standards:
• IEEE 802.1d: Media Access Control (MAC) Bridges
• IEEE 802.1w: Part 3: Media Access Control (MAC) Bridges—Amendment 2: Rapid Reconfiguration
• IEEE 802.1s: Virtual Bridged Local Area Networks—Amendment 3: Multiple Spanning Trees
Spanning tree configuration task list
Plan the role (root bridge or leaf node) of each device in an MSTI before starting the configuration, and
then configure the devices as planned. An MSTI has only one root bridge, and all the other devices in the
MSTI are leaf nodes.
Complete the following tasks to configure MSTP:
Task Remarks

root bridge
