This chapter provides procedures for configuring the basic parameters of your Cisco router, including
global parameter settings, routing protocols, interfaces, and command-line access. It also describes the
default configuration on startup.Individual router models may not support every feature described throughout this guide. Features not
supported by a particular router are indicated whenever possible
This software configuration guide provides instructions for using the Cisco command-line interface (CLI) to configure features of the following Cisco 1800 series integrated services fixed-configuration routers: •Cisco 1801, Cisco 1802, and Cisco 1803 DSL Access Routers •Cisco 1811 and Cisco 1812 Ethernet Access Routers
This preface describes the intended audience, the organization of this guide, and the text and command conventions used throughout the guide. The preface includes the following topics:...
"Secure Router Configuration - IOS 15.1" aims at providing network security engineers with the knowledge and skills needed to secure Cisco IOS router based networks. Readers of this book will be able to secure the network environment using existing Cisco IOS Software features, as well as install and configure components of the Cisco IOS Software, such as zone-based policy firewall and Cisco IOS Intrusion Prevention System (IPS).
You should also install and configure a TFTP server in your lab
network. This is fairly easy to do, and any PC or laptop can function
as your TFTP server for the purposes of this lab. For more
information about finding TFTP software, see Backing Up Router
Configuration Files in the Basic Router Maintenance and
Troubleshooting section of the Basic Router Operation Tutorial.
Organized for maximum efficiency: describes actual commands and options in the sequence they should be used
Helps network pros eliminate time-consuming documentation searches
Extensive updates: IPv6, MPLS, AutoQoS, SIP, MGCP, voice troubleshooting, VPNs, security, and more
"At-a-glance" illustrations offer fast answers and easy double-checking
Upon completing this lesson, you will be able to:
Use the CLI to interact with the Cisco IOS software, given an operational router
Verify the default configuration of the device, given a functioning router
Complete the initial device configuration, given a functioning router
Configure IP addresses and IP subnet masks on router interfaces, given a functioning router
This chapter shows you how to configure Voice over IP (VoIP) on the Cisco 3600 series. For a
deion of the commands used to configure Voice over IP, refer to the “Voice-Related
Commands” chapter in the Voice, Video, and Home Applications Command Reference.
VoIP enables a Cisco 3600 series router to carry voice traffic (for example, telephone calls and faxes)
over an IP network.
Linux can be a terrific "poor man’s" router. It takes a little more startup configuration than a typical
hardware router, but once it is going, very little will stop it, at least in our experience. We’ve been using
the router setup detailed below in production for six months now (a few months more worth of
pilot-testing), and the only faults we’ve encountered were either service-provider related or due to
water-soaked cables -- unbelievable, but true, and a really long story I won’t get into here!...
This chapter provides information about configuring Layer 2 features on the Cisco 7600 Series Ethernet
Services Plus (ES+) and Ethernet Services Plus T (ES+T) line card on the Cisco 7600 series router.
Cable a network similar to the one shown in the diagram. Any router that meets the interface
requirements displayed on the above diagram may be used. For example, router series 800, 1600,
1700, 2500 and 2600 or any such combination can be used. Please refer to the chart at the end of
the lab to correctly identify the interface identifiers to be used based on the equipment in the lab. The
configuration output used in this lab is produced from 1721 series routers. Any other router used may
produce slightly different output.
This is the first part of the Semester 2 practical final exam. It will focus on your ability to configure
the lab routers to communicate properly. You will work in teams of five to configure all five Cisco
routers and attached workstations so that they share an IP addressing / subnet scheme and a common
dynamic routing protocol (e.g.: RIP, IGRP etc.). This will enable them to route packets from a
network on router LAB-A to a network on router LAB-E. The NVRAM (startup config file) in all five
routers will be erased prior to starting the exam. Your team will select a single class...
This chapter presents the basics of configuring the 1900 and 2950 Catalyst switches
as well as Cisco routers. As you continue throughout this book, you will build upon
these fundamental and important concepts for accessing, configuring, and managing
your Cisco devices. I am making the assumption that you have never configured a Cisco device
before and therefore will begin with the very basics by explaining the operating system that these
devices use, the advantages that Cisco’s operating system provides, and how to use some basic
operating system commands to configure your Cisco device....
Practical Cisco Routers is an excellent "first purchase" for anyone interested in Router technology. It provides hands-on steps and easy-to-follow screen captures for the basic configuration of a new router. This book provides the basic knowledge base needed to cope with a rapidly proliferating technology. Practical Cisco Routers is written in an easy-to-understand and straightforward manner to provide the essential information for technology professionals new to routers by an author who teaches the information daily.
A new router will not find its configuration file when started and should automatically enter the setup
dialog. If the router has already been configured the setup command may be used at the command
line while in privileged mode. The setup dialog prompts for basic setup options, such as which
protocols will be used and the IP address and subnet mask for each interface the router has. The
setup dialog provides default values for most of the configurable options. The user can either accept
these or enter their own.
