Switches exchange which type of messages with other switches to communicate about STP?

Spanning Tree Protocol communicates using Bridge Protocol Data Units. A BPDU carries the topology information switches need to run STP, such as the identity of the root bridge, the cost to reach that root, and the transmitting bridge’s ID and port. With this data, each switch can select its root port (the best path toward the root) and determine which ports should be designated on each network segment, building a loop-free tree. There are two BPDU flavors: the configuration BPDU used to establish the tree, and the topology-change BPDU used to signal changes. The correct term for these messages is Bridge Protocol Data Unit. Other terms listed aren’t used to describe STP messages.
