Explanation

RSTP (Rapid Spanning Tree Protocol) operates at Layer 2 - the Data Link layer - of the OSI model. STP and RSTP are designed to prevent Layer 2 switching loops in Ethernet networks by logically blocking redundant paths between switches. These protocols work with MAC addresses and switch ports, which are Data Link layer concepts. Layer 1 (Physical) deals with electrical signals and cabling. Layer 3 (Network) handles IP routing. Layer 4 (Transport) manages end-to-end communication (TCP/UDP). Loop prevention for switched/bridged networks is strictly a Layer 2 function.
