Appendix B: Spanning Tree Protocol

B.1 Spanning Tree Protocol

In Chapters 3 and 9, we have seen that the Ethernet technology, born for applications in local area network (LAN) and private networks, is one of the candidates for the development of a next generation, packet-based, metro network.

In this appendix, we describe one of the main protocols of the Ethernet suite: the spanning tree. We look at all the advantages of the spanning tree protocol, but also the scalability limits that its adversaries underline to discourage its use in the carrier network.
