| Lab 5.3.1 Router setup challenge - Overview Estimated time: 60 min. Objectives: To learn the procedure to recover when a password is forgotten. Apply what you have learned in chapter 14 in the Cisco Networking Academy First-Year Companion Guide, online chapter 5 and Lab 5.2.2.1 on the setup utility. Demonstrate your ability to subnet a class B IP address. Learn to use setup mode to set basic configuration parameters for the router. Use HyperTerminal to capture the running configuration for the routers. Background: When you first open up a router and the operating system is loaded, you have to go through the process of initial setup. In this scenario, you have just received a shipment of new routers and you need to setup a basic configuration. You have received a class B IP network address of 156.1.0.0, and you will need to subnet your class B address using 5 bits for you subnets. Use the standard 5-router diagram on the previous page to determine which subnetwork numbers and which IP addresses you will use for the 8 networks you will need to define. For this lab, setup all five routers. Be sure to configure the router you are using with the console port. Tools / Preparation: Prior to starting this lab you will need to have the equipment for the standard 5-router lab available (routers, hubs, switches, cables, etc.). If the routers are configured then the Lab Assistant or Instructor will have to erase the configuration before you begin. The routers, hubs and workstations should be labeled. This lab assumes that you have completed the prior lab and that the lab equipment (routers, hub, workstations, etc.) are assembled and connected in the standard lab topology. Work in teams of 3 to 5. Before beginning this lab you may want to review Chapters 14 in the Cisco Networking Academy First-Year Companion Guide and Semester 2 On-line Chapter 5. Resources Required: One Floppy Disk. 5 PC workstations (min.) with Windows operating system and HyperTerminal installed. 5 Cisco Routers (model 1600 series or 2500 series with IOS 11.2 or later). 4 Ethernet hubs (10BASE-T with 4 to 8 ports). One Ethernet switch (Cisco Catalyst 1900 or comparable). 5 serial console cables to connect workstation to router console port (with RJ45 to DB9 converters). 3 Sets of V.35 WAN serial cables (DTE male/ DCE female) to connect from router to router. CAT5 Ethernet Cables wired straight through to connect routers and workstations to hubs and switches. AUI (DB15) to RJ45 Ethernet transceivers (Quantity depends on the number of routers with AUI ports) to convert router AUI interfaces to 10BASE-T RJ45. Websites Sites Required: Routing basics General information on routers 2500 series routers 1600 series routers Terms and acronyms IP routing protocol IOS command summary Notes: Step 1 - Login to the router in enable mode and issue the setup command. If the router has not been configured it may enter setup automatically. If the router is configured you will need to login to the router and enter enable mode and issue the setup command. Step 2 - Follow the on-screen prompts and use the following information: Use Lab-A to Lab-E as the host name for the routers. The enable secret password should be class. Use IGRP for you routing protocol with autonomous system number 1. Be sure to specify the correct IP addresses and number of subnet bits for each interface. When you are asked to "use this configuration?" answer yes 1. How many subnets can you create with a 5-bit mask and a Class B network address? 2. How many hosts per subnet ? 3. What will the subnet mask be in decimal? Step 3 - Document you configuration. After answering yes to "Use this configuration?" you will want to capture the output from the show running-config command of all five routers to hand into your instructor. You do this in HyperTerminal by clicking on the Transfer then Capture Text. In the Capture Text window you can specify the file name and where you want the capture text to be saved. Save your text to a floppy disk and name the text file output from each router the same as the router name (lab-a.txt, lab-b.txt etc.) Then click on start button to start capturing text. Now, from an enable mode prompt issue the show running-config command. After capturing the running-configuration click on Transfer then Capture text, then Stop. The output from the show running-configuration will be on the floppy disk. Take your floppy disk to a computer that has a printer and print the captured text, or display the text file for your instructor. Step 4 - Repeat for all 5 routers. 4. See answers section for running configuration from all five routers using the class B address with 5 bits of subnetting.
