Multiple Spanning Tree Protocol
NETWORK PROTOCOL THAT BUILDS A LOOP-FREE LOGICAL TOPOLOGY FOR ETHERNET NETWORKS
Multiple Spanning Tree protocol; Common Spanning Tree; MISTP
The Multiple Spanning Tree Protocol (MSTP) and algorithm, provides both simple and full connectivity assigned to any given Virtual LAN (VLAN) throughout a Bridged Local Area Network. MSTP uses BPDUs to exchange information between spanning-tree compatible devices, to prevent loops in each MSTI (Multiple Spanning Tree Instances) and in the CIST (Common and Internal Spanning Tree), by selecting active and blocked paths.
