common internal spanning tree?
"The root bridge for Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP) is determined by comparing attributes of each bridge in the network.
The protocol considers bridge priority first. If more than one bridge has the same priority, then the protocol must consider the bridge ID. The bridge with the lowest ID becomes the root bridge. For MSTP, this bridge is called the Common and Internal Spanning Tree (CIST) Root because it is the root of the entire physical network."
