2-6 MSTP
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 a 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.
