  • This lab will focus on the ability to connect a PC to a router or a switch in order to establish a console session and observe the user interface. A console session allows the user to check or change the configuration of the switch or router and is the simplest method of connecting to one of these devices. This lab should be performed twice, once with a router and once with a switch to see the differences between the user interfaces. Start this lab with the equipment turned off and with cabling disconnected. Work in teams of two with one for the router and one for...

  • This lab focuses on the ability to connect the physical cabling between Ethernet LAN devices such as hubs and switches and the appropriate Ethernet interface on a router. The computer(s) and router should be preconfigured with the correct IP network settings. Start this lab with the computer(s), router and hub or switch all turned off and unplugged.

  • This lab helps the student become familiar with the router show commands. The show commands are the most important information-gathering commands available for the router. • show running-config (or show run) is probably the single most valuable command to help determine the current status of a router, because it displays the active configuration file running in RAM. • show startup-config (or show start) displays the backup configuration file that is stored in non-volatile RAM (NVRAM).

  • This lab introduces the CCNP lab equipment and certain IOS features that might be new to you. This introductory activity also describes how to use a simple text editor to create all (or part) of a router configuration file. After you create a text configuration file, you can apply that configuration to a router quickly and easily by using the techniques described in this lab.

  • Routers built around a single-stage crossbar and a centralized scheduler do not scale, and (in practice) do not provide the throughput guarantees that network operators need to make ecient use of their expensive long-haul links. In this paper we consider how optics can be used to scale capacity and reduce power in a router. We start with the promising load-balanced switch architecture proposed by CS. Chang. This approach eliminates the scheduler, is scalable, and guarantees 100% throughput for a broad class of trac.

  • 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...

  • 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.

  • This chapter addresses what most people think about when they start to secure a router—authenticating users and restricting access. There are many more ways to access Cisco routers than most network administrators realize. Each of these methods can have different authentication methods and can be set to allow various levels of privilege access. It is important that all methods of access are either secured or disabled.

  • Every time we teach a class to get students started with Cisco and networking technologies, there are always some common things that bug and stop students from getting some basic topics.We, as instructors, are always asked if there is a basic to the basic course they are taking. That’s why we are putting this router training white paper out—to help students with some of those “basic of the basic concepts.” This paper won’t attempt to answer all your questions, but it will definitely help with some of those concepts to make your class experience more enjoyable....

  • Each workstation should be able to ping the attached router. If for some reason this is not the case, troubleshoot as necessary. Check and verify that the workstation has been assigned a specific IP address and default gateway. If running Windows 98, check using Start Run winipcfg. If running Windows 2000 or higher, check using ipconfig in a DOS window.

  • This lab focuses on configuring a basic router-to-router WAN and then troubleshooting Layer 1 cabling problems and workstation Layer 3 IP addressing problems. Note: The two routers need to be preconfigured by the instructor or lab assistant to have the correct IP addresses on their LAN and WAN interfaces. Router A will provide the clocking signal as DCE. Use the prior lab “Basic Routed WAN” to set up this lab prior to starting the troubleshooting.

  • This book provides a succinct, in-depth tour of all the new features and functions in IPv6. It guides you through everything you need to know to get started, including how to configure IPv6 on hosts and routers and which applications currently support IPv6. The new IPv6 protocols offers extended address space, scalability, improved support for security, real-time traffic support, and auto-configuration so that even a novice user can connect a machine to the Internet.
