Bandwidth and path and the above table costs。

Configuration process

Switch#configure terminal

Switch(config)#interface <if-name>

Switch(config)#spanning-tree mst instance <instance-id> path-cost <path-cost>

Configure the version number of the send protocol package

The default configuration sends the MSTP protocol package with a configuration range of

0-3 and a mapping relationship of 0-stp, 2-rstp, 3-mstp。

Configuration process：

Switch#configure terminal

Switch(config)#interface <if-name>

Switch(config)# spanning-tree mst force-version <version-id>

Configure connection type

If connected to the other port a port through the point-to-point mode, and become a local port

(designated port, RSTP proposal-agreement through the designated port) (proposal agreement)

negotiation a rapid migration of its connected ports become the root port to determine a loop free

topology。

Here is a brief introduction to the negotiation process of proposal-agreement。

When the switch receives a proposal message on one of its ports and the port is selected as

the new root port, RSTP forces all other ports to synchronize the new root port information。

If all other ports are synchronized with the better (superior) root information received from

the root port, the switches are synchronized。

When RSTP forces it to synchronize the new root information, if a specified port is in the

forwarding state and is not configured as an edge port, it migrates to the blocking state. Typically,

when the RSTP forces a port to synchronize a new root message and the port does not satisfy the

above conditions, the port state is set to blocking。

When all ports are synchronized, the switch sends a agreement message to the corresponding

port of the root port. When the switch is connected to a point-to-point connection in their port role

of agreement, the RSTP immediately transfers the port state to forwarding。

If shared connection, the 802.1D port is calculated to determine the state of the port。

The default port connection type is point-to-point connection。

The connection type of the configuration port is point-to-point connection：
