This volume is divided into two parts : the first part includes chapters on the user interface, configuring lines and interfaces, access lists, routing protocols, and dial-on-demand routing and security , the second part is a classic O'Reilly-style quick reference to all the commands that you need to work with TCP/IP, including the lower-level protocols on which it relies, and lots of examples of the most commonly encountered configuration steps for the routers themselves.
