8.2.6 Configure MSTP Protection Function
Background Information
BPDU protection
For the access layer device, the access interface usually connects with user
terminal (such as PC) or file server. At this time, the access interface can be
configured the as edge interface to realize interface fast switching. Under normal
circumstances, the edge interface will not receive BPDU message of STP. But if
anyone forges configuration message and attacks switch maliciously. When the
edge interface receives the configuration message, system will configure these
interfaces to be non-edge interface automatically and will calculate STP again.
This will results in network topology concussion. BPDU protection function can
prevent this network attack.

- Cost is ercb the domain root is rrb the inner root path cost is ircb the 187
- Designated bridge id is b the designated port is b the designated port id 187
- In cist priority vector is composed of the total root outer root path cost domain 187
- In order to facilitate the subsequent description we make the following 187
- In the initial condition the information carried in the message sent out by the 187
- Is pb the id of port receiving bpdu message is pb 187
- Msti priority vector calculation method as follow 187
- Pb port of the bridge b is as follow the total root is rb the outer root path 187

- The message the most important information carried in the message is the 187
- The mstp role of all bridges is computed according to the carrying information in 187
- A switch a role selection process 190
- And the switchb is better than switchc the link path costs are 4 5 and 10 190
- Another domain alone 190
- Figure 8 1 supposing that the bridge priority of switcha is better than switch b 190
- In initial state the port of every device will be calculated to be the designated port and 190
- Role selection process 190
- State of the figure 8 1 is shown in the table 8 2 190
