¾MSTP

MSTP divides a network into several MST regions. The CST is generated between these MST regions, and multiple spanning trees can be generated in each MST region. Each spanning tress is called an instance. As well as STP, MSTP uses BPDUs to generate spanning tree. The only difference is that the BPDU for MSTP carry the MSTP configuration information on the switches.

¾Port States

In an MSTP, ports can be in the following four states:

zForwarding: In this status the port can receive/forward data, receive/send BPDU packets as well as learn MAC address.

zLearning: In this status the port can receive/send BPDU packets and learn MAC address.

zBlocking: In this status the port can only receive BPDU packets.

zDisconnected: In this status the port is not participating in the STP.

¾Port Roles

In an MSTP, the following roles exist:

zRoot Port: Indicates the port that has the lowest path cost from this bridge to the Root Bridge and forwards packets to the root.

zDesignated Port: Indicates the port that forwards packets to a downstream network segment or switch.

zMaster Port: Indicates the port that connects a MST region to the common root. The path from the master port to the common root is the shortest path between this MST region and the common root.

zAlternate Port: Indicates the port that can be a backup port of a root or master port.

zBackup Port: Indicates the port that is the backup port of a designated port.

zDisabled: Indicates the port that is not participating in the STP.

The following diagram shows the different port roles.
