4.5.3 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).
