The implementation of MSTP is according to IEEE 802.1Q 2005
Clause 13 – Multiple Spanning Tree Protocol. 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. Proper configuration of MSTP in an 802.1Q VLAN
environment can ensure a loop-free data path for a group of vlans
within an MSTI. Redundant path and load balancing in vlan
environment is also achieved via this feature.A spanning tree
instance called CIST(Common and Internal Spanning Tree) always
exists . Up to 64 more spanning tree instances (MSTIs) can be
provisioned.
