Labs Content Information

LAB 1	Networking overview In this session, you´ll learn about the various devices used on networks and uncover the functions of each one. You´ll also learn about the International Organization for Standardization (ISO) that developed the OSI reference model and why it´s important when it comes to dealing with routers. You´ll also learn ... Exactly what you need to know about TCP/IP and IP addressing to begin working with routers, including decimal to binary conversion How to use subnets and subnet masks The primary hardware components in routers, including console ports, serial ports, WAN cards, Ethernet® ports and more The different methods a router uses to boot and how to decipher the messages that appear during the boot process The differences between access modes on a router and how to get into each one How to login to a router using the console port and the common commands used to identify router settings
LAB 2	Initial and manual router configuration In this session, you´ll learn how to use the Initial Configuration Dialog to set up a non-configured router. Then you´ll discover the commands necessary to manually configure a variety of settings on a router. You´ll find out how to set bandwidth and clock rate settings on serial interfaces, manually configure IP address settings on all network interfaces, set passwords and more. You´ll find out ... The difference between global and interface parameters How to launch the System Configuration Dialog on a router that already has a configuration loaded How to save your changes to the startup configuration file What actually happens on the router when you copy the startup configuration to the running configuration and why it´s important to understand this process The difference between enable, enable secret and virtual terminal passwords
LAB 3	Configuring static routes and host tables In this session, you´ll find out the difference between static and dynamic routing. You´ll also learn the principles of static routing and how to program static routes on a Cisco® router. You´ll then discover how to manually create host tables that will allow your router to communicate with other routers and computers using host names instead of just IP addresses. You´ll learn ... What it takes to build static routes on a network with multiple routers How to manually enter host table information How to integrate a host table from a text file into your running configuration How to specify a default gateway for your router to uses The difference between enable, enable secret and virtual terminal passwords
LAB 4	Configuring Routing Protocols This session will teach you the basics of routing protocols, and you´ll discover the difference between link-state and distance-vector routing protocols. You´ll learn about the metrics used by routing protocols to determine path selection. You´ll also find out how to decide when to use static routing versus dynamic routing. Also in this session ... Uncover the difference between routed protocols and routing protocols Learn the basics of how data travels from end stations through intermediate stations and on to the destination end station Discover how easy it is to implement RIP routing and configure it on a Cisco® router Find out what an autonomous system number is and how it is used when configuring IGRP Learn about the other routing protocols that are available on Cisco routers and when to use—or not use—each one
LAB 5	Telnet sessions and router performance This informative session starts off by teaching you how to establish Telnet sessions with routers. You´ll learn the limitations of Telnet sessions and how to tell if someone is connected to your router via a Telnet session. You´ll also find out how to quickly disconnect an unauthorized Telnet user from your router. You´ll also learn ... How to identify the processes running on your router and how to shut down the ones you don´t need to improve router performance How to clear interface counters and get current interface transmission statistics A quick way to take a look at processor utilization on your router over several time intervals How to determine memory utilization on a Cisco router What Cisco and third-party software is available for you to monitor router performance
LAB 6	Router troubleshooting Very rarely do things always work the way they´re supposed to and that´s why we´ve created this eye-opening session. We´ll show you tried-and-tested methods to troubleshoot a problematic router and how to use the debug command to isolate router problems. You´ll find out how to debug serial and Ethernet® interfaces to quickly find out if the problem you´re having is related to your configuration or if it´s a hardware failure. You´ll also find out ... Why debugging information doesn´t appear in a Telnet session window How to view the configuration register setting of the router to make sure it´s booting into the correct mode How to modify the configuration register setting to boot the router into a diagnostic mode How to troubleshoot a problematic console connection How to quickly recover a lost router password without having to reload all your router settings
LAB 7	Router security Nothing is more important on today´s networks than security, and this session will show you how to increase the security of your network by using the features of a Cisco® router. You´ll learn how to build standard access lists that can be used to block access to your network from a single computer or an entire network. You´ll also learn ... The difference between standard and extended access lists How to block Telnet access to your router using an extended access list How to protect your Internet-connected systems using Network Address Translation (NAT) How to configure NAT to translate not only addresses but ports as well
LAB 8	Network Address Translation (NAT) This informative session starts off by teaching you how to establish Telnet sessions with routers. You´ll learn the limitations of Telnet sessions and how to tell if someone is connected to your router via a Telnet session. You´ll also find out how to quickly disconnect an unauthorized Telnet user from your router. You´ll also learn ... How to identify the processes running on your router and how to shut down the ones you don´t need to improve router performance How to clear interface counters and get current interface transmission statistics A quick way to take a look at processor utilization on your router over several time intervals How to determine memory utilization on a Cisco router What Cisco and third-party software is available for you to monitor router performance
