How MSTP works 

MSTP divides an entire Layer 2 network into multiple MST regions, which are connected by a 
calculated CST. Inside an MST region, multiple spanning trees are calculated. Each spanning tree is 
an MSTI. Among these MSTIs, MSTI 0 is the IST. Like STP, MSTP uses configuration BPDUs to 
calculate spanning trees. An important difference is that an MSTP BPDU carries the MSTP 
configuration of the bridge from which the BPDU is sent. 

CIST calculation 

The calculation of a CIST tree is also the process of configuration BPDU comparison. During this 
process, the device with the highest priority is elected as the root bridge of the CIST. MSTP 
generates an IST within each MST region through calculation. At the same time, MSTP regards each 
MST region as a single device and generates a CST among these MST regions through calculation. 
The CST and ISTs constitute the CIST of the entire network. 

MSTI calculation 

Within an MST region, MSTP generates different MSTIs for different VLANs based on the 
VLAN-to-instance mappings. For each spanning tree, MSTP performs a separate calculation 
process similar to spanning tree calculation in STP. For more information, see "

Calculation process 

of the STP algorithm

." 

In MSTP, a VLAN packet is forwarded along the following paths: 

•

 

Within an MST region, the packet is forwarded along the corresponding MSTI. 

•

 

Between two MST regions, the packet is forwarded along the CST. 

Implementation of MSTP on devices 

MSTP is compatible with STP and RSTP. Devices that are running MSTP and that are used for 
spanning tree calculation can identify STP and RSTP protocol packets. 

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: 

•
