Basic Configurations

This chapter contains basic configuration examples for connecting a Cisco 700 series router to an Internet service provider (ISP) or to a central site, such as your company network. It is assumed that your router is cabled as described in the Cisco 700 Quick Reference Guide. Before you proceed with the examples in this chapter, have the information regarding ordering the ISDN line and the connection information in the Cisco 700 Quick Reference Guide (shipped with your router package) available.

The chapter is written so that a knowledgeable beginner can perform a basic configuration of the router, guided by the examples. Explanations are kept to a minimum, but they do show how the individual commands fit into the framework of a configuration.

This chapter has the following sections:
