Layer2 based loop-free protection mechanism – Each device using STP/RSTP send BPDU frames, and root bridge, root port, designated port, backup port and alternate port are decided by BPDU frame.

• Some topology (instance) can be treated with same STP network • The VLANs are divided into some groups (instances), and blocking port is decided in the each group (instance). • MSTP is based on RSTP (IEEE 802.1w), and can used RSTP independently in each VLAN – Enables load balancing, over a large number of VLANs • The restructuring of each VLAN becomes possible. As a result, the time required to restructure can be shortened. NEC Confidential

See below

The MSTP maximum hop count value is the maximum number of hops in the region. The MSTI root bridge sends BPDUs with the hop count set to the maximum value. When a bridge receives this BPDU, it decrements the remaining hop count by one and propagates this hop count in the BPDUs it sends. When a bridge receives a BPDU with a hop count of zero, the bridge discards the BPDU NEC Confidential
