3-4-1. RSTP

The Rapid Spanning Tree Protocol (RSTP) provides rapid convergence of the
spanning tree by assigning port roles and by determining the active topology.
The RSTP builds upon the IEEE802.1D STP protocol to select the switch with
the highest switch priority as the root switch.

3-4-2. RSTP

3-4-3. MSTP

The Multiple Spanning Tree Protocol (MSTP) algorithm and protocol provides
simple and full connectivity for frames assigned to any given VLAN throughout
a Bridged Local Area Network comprising arbitrarily interconnected Bridges,
each operating MSTP, STP (Clause 8 of IEEE Std 802.1D, 1998 Edition), or
RSTP (Clause 17 of IEEE Std 802.1D,1998 Edition).

MSTP allows frames assigned to different VLANs to follow separate paths,
each based on an independent Multiple Spanning Tree Instance (MSTI), within
Multiple Spanning Tree (MST) Regions composed of LANs and or MST
Bridges. These Regions and the other Bridges and LANs are connected into a
single Common Spanning Tree (CST).
