Spanning Tree Protocol (STP) allows Ethernet LANs to have the added benefit of redundant links while overcoming the known problems that occur when those extra links are added. Redundant links in a LAN design allow the LAN to keep working even when some links fail or even when entire switches fail. Proper LAN design should add enough redundancy so that no single point of failure crashes the LAN; STP allows the design to use redundancy without causing some other problems.
This chapter discusses the concepts behind STP. In particular, it discusses ...
