MISTP: Multiple Instances Spanning Tree Protocol
Multiple Instances Spanning Tree Protocol (MISTP) is a Cisco standard which allows several VLANs to be mapped to a reduced number of spanning-tree instances. This is possible since most networks do not need more than a few logical topologies. Each instance handles multiple VLANs that have the same Layer 2 topology. The Multiple Spanning Tree (MST) Protocol defined in IEEE 802.1s is based on the Cisco MISTP.
