Summary:This chapter discusses wide area network (WAN) technologies and topologies. A WAN connects other networks, or groups of networks separated geographically or by organizational design. WAN provides the means for the networks on which those devices reside to reach remote destinations. A WAN can be configured to provide connectivity to any of the end devices; a single server at a distant location can be connected via a WAN to the rest of the organizational network. This chapter provides an overview of WAN technologies provided by Cisco, including their features and salient points. It also provides configuration details for deployment and support of WANs, especially on routers. The chapter also examines to-point connections and their benefit, the related protocols, and a simple point-to point configuration. It describes Frame Relay packets and the fields they contain. Finally, the chapter explains troubleshooting in a Frame Relay environment and the related troubleshooting commands.
