Troubleshooting Remote Access Networks (CCIE Professional Development)

This chapter is divided into two separate sections that cover dial design solutions and dial configuration solutions.

The dial design solutions section covered the essentials of dial-in network connectivity, dial-out network connectivity, and DDR along with dial-out for support purposes and large-scale dial-out services.

The dial configuration solutions section provided detailed information about common and specific dial configurations, including the following:

• Text dial-in configuration

• PPP dial-in configuration

• Large-scale dial-in configuration

• Text dial-out configuration

• PPP dial-out configuration

• Large-scale dial-out configuration

• Dial-on-demand backup configuration

Before the troubleshooting process starts, it is important to understand entirely the design and configuration specifics of the dial solution. This gives you a better understanding of the troubleshooting methodology that's used for dial in the next chapter.
