Question: 1 / 655

What BPDU version does RSTP use?

802.3

802.1W

Rapid Spanning Tree Protocol (RSTP) uses the Bridge Protocol Data Unit (BPDU) version defined by the IEEE 802.1W standard. RSTP is an evolution of the original Spanning Tree Protocol (STP), which is outlined in the IEEE 802.1D standard. However, RSTP introduced enhancements to how bridges and switches communicate their status and topology changes, which is encapsulated in the BPDU format defined by 802.1W.

This essential distinction allows RSTP to provide faster convergence times and improved network stability compared to its predecessor. The BPDU used in RSTP includes additional information, such as flags indicating the protocol version and entries for bridge priority and port role, which are key for the rapid transitions RSTP aims to achieve. Thus, the answer identifies the correct standard associated with RSTP's operation and its optimized features.
