Most larger networks implement redundancy in case of failure, and this redundancy canbe multiple WAN connections, multiple paths in a Layer 3 network, and/or multiple paths in a Layer 2 network. This chapter focuses on Layer 2 redundancy and the problems caused by Layer 2 loops, including two features that are commonly used to solve these problems: the Spanning Tree Protocol (STP) and EtherChanneLAuthentication Objectives 13.0113.1 Layer 2 RedundancyTo help design campus networks, Cisco has developed a hierarchical model that includes 3 layers. Cisco uses this model to simplify the design, implementation, and management of large networks. While traditional network design typically placed network services at the center of the network and users at the periphery, many aspects of the networking landscape have changed in the last decade, including improvements in applications, the development of graphical user interfaces (GUIs), the emergence of multimedia applications, the explosive growth of the Internet, and rapid changes in user traffic patterns. This model from Cisco is designed to accommodate these rapid changes.13.1.1 Hierarchical Campus Network Design
