Chapter 1-13 Labs Labs:
Chapter 1: Computer Basics
| There are no labs in Chapter 1
Chapter 2: WANs and Routers
2.2.2 | In this lab you will examine a Cisco router to gather information about its physical characteristics and begin to relate Cisco router products to their function. You will determine the model number and features of a specific Cisco router including which interfaces are present and to which cabling and devices they are connected.
2.2.3.1 | This lab will help you develop an understanding of how the Cisco lab routers are set up and connected for the Semester 2 topology. You will examine and document the physical connections between these routers and the other lab hardware components such as hubs, switches and workstations.
2.2.3.2 | This lab will help you develop an understanding of how the Cisco lab routers and workstations are configured for the Semester 2 topology. You will use IOS commands to examine and document the IP network configurations of each router.
Chapter 3: Router CLI
3.2.1 | This lab will introduce the Cisco Internetwork Operating System (IOS) command line user interface. You will log on to the router and use different levels of access to enter commands in "User Mode" and "Privileged Mode"
3.2.2 | When using router operating systems such as Cisco IOS, you will have to know each of the different user modes a router has and what each one of them is for. Memorizing every command in all of the user modes would be time consuming and pointless. Try to develop an understanding of what commands and functions are available with each of the modes. In this lab, you will work with the topology and the six main modes available with most routers: User EXEC Mode Privileged EXEC Mode (also known as Enable Mode) Global Configuration Mode Router Configuration Mode Interface Configuration Mode Sub-interface Configuration Mode
Chapter 4: Router Components
4.2.4 | In this lab you will use the show cdp command. Cisco Discovery Protocol (CDP) discovers and shows information about directly connected Cisco devices (routers and switches). CDP is a Cisco proprietary protocol that runs at the data link layer (layer 2) of the OSI model. This allows devices that may be running different network layer 3 protocols such as IP or IPX to learn about each other. CDP begins automatically upon a device's system startup, however if you are using Cisco IOS Release 10.3 or newer version of IOS you must enable it on each of the device's interfaces by using the cdp enable command. Using the command show cdp interface you will gather information CDP uses for its advertisement and discovery frame transmission. Use show cdp neighbors and show cdp neighbors detail to display the CDP updates received on the local router.
4.3.5 | In this lab, you will use the show cdp command. Cisco Discovery Protocol (CDP) discovers and shows information about directly connected Cisco devices (routers and switches). CDP is a Cisco proprietary protocol that runs at the data link layer (layer 2) of the OSI model. This allows devices that may be running different network layer 3 protocols such as IP or IPX to learn about each other. CDP begins automatically upon a device's system startup, however if you are using Cisco IOS Release 10.3 or newer version of IOS you must enable it on each of the device's interfaces by using the cdp enable command. Using the command show cdp interface you will gather information CDP uses for its advertisement and discovery frame transmission. Use show cdp neighbors and show cdp neighbors detail to display the CDP updates received on the local router.
4.4.2 | In this lab you will work with the telnet (remote terminal) utility to access routers remotely. You will telnet from your “local” router into another “remote” router in order to simulate being at the console on the remote router.
4.4.3 | In this lab you will use ICMP or Internet Control Message Control. ICMP will give you the ability to diagnose basic network connectivity. Using ping xxx.xxx.xxx.xxx will send an ICMP packet to the specified host and then wait for a reply packet from that host. You can ping the host name of a router but you must have a static host lookup table in the router or DNS server for name resolution to IP addresses.
4.4.4 | In this lab you will use the IOS traceroute command. The trace route command uses ICMP packets and the error message generated by routers when the packet exceeds its Time To Live (TTL).
4.4.7 | In this lab you will use show interface and clear counters. The router keeps very detailed statistics about data traffic it has sent and received on its interfaces.
4.5.1 | Through the use of show commands, you should be able to see which interfaces are up (using show interface), what devices the router is connected to (using show CDP neighbors) and how the user can get there (using show protocols). With the information received from the show commands, you should be able to remotely access the neighboring routers (using telnet) and through the use of troubleshooting commands (such as ping and trace) you should be able to see which devices are connected. Your final goal is to construct a logical topology drawing of the network by making use of all the above commands without referring to any diagrams ahead of time.
Chapter 5: Router Startup and Setup
5.2.3 | In this lab you will use the command setup to enter setup mode. Setup is a Cisco IOS utility (or program) that can help get some of the basic router configuration parameters established. Setup is not intended as the mode for entering complex protocol features in the router. Rather the purpose of setup mode is to bring up a minimal configuration for any router that cannot find its configuration from some other source.
5.3.1 | 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 above to determine which subnetwork numbers and which IP addresses you will use for the 8 network you will need to define. For this lab, setup all five routers. Be sure to configure the router you are using with a console port.
Chapter 6: Router Configuration
6.1.2 | In this lab you will use the Windows terminal emulation program, HyperTerminal, to capture and upload a router configuration as an ASCII text file.
6.1.4 | In this lab we will use a TFTP (Trivial File Transfer Protocol) server to save a copy of the router's configuration file.
6.2.1 | In this lab you will use the router's Global configuration mode and enter one-line commands that change the entire router.
6.2.5 | In this lab you will use the router’s interface configuration mode to configure an IP address and subnet mask for each router interface.
6.3.3 | There will be circumstances where the password for a router needs to be reset. The password may have been forgotten, or the previous administrator may have left the employment of the company that owns the router. The technique described requires physical access to the router, so that the console cable may be plugged in. Since this technique is well known, it is vital that routers are in a secured location, with limited physical access.
6.4.1 | You and your group are administrators of a LAN. Due to the rapid expansion of this company, you need to link the headquarters (your group's router) to the rest of network. Before starting this lab the, Lab Assistant or the Instructor should erase the running configuration and the startup configuration for Lab-A only and make sure that the rest of the routers are configured with the standard lab setup. You will also need to verify your workstation IP configuration so you can test the connectivity between workstations and routers.
6.4.2 | This lab is intended to help you become familiar with Cisco ConfigMaker. Cisco ConfigMaker is an easy-to-use Windows 95/98/NT application that configures Cisco routers, switches, hubs, and other devices.
6.4.3 | With Cisco IOS version 11.0, the ip http server command allows the router to act as a limited HTTP (Hyper Text Transfer Protocol) web server
Chapter 7: IOS Images
7.1.3 | In this lab you will gather information on the version of IOS software that is currently running on the router. You will also check the configuration register values to see where the router is currently configured to boot from.
Chapter 8: Router Configuration 2
8.1.2 | There will be circumstances where the password for a router needs to be reset. The password may have been forgotten, or the previous administrator may have left the employment of the company that owns the router. The technique described requires physical access to the router, so that the console cable may be plugged in. Since this technique is well known, it is vital that routers are in a secured location, with limited physical access.
8.2.1 | In this lab you will configure one of the 5 lab routers from the command line by yourself without the use of any notes, only the network topology. You may use the router help facility and the router diagram above. Your goal will be to configure the router as quickly as possible without errors. You will also configure the IP settings for one of the corresponding Ethernet attached workstations.
Chapter 9: TCP/IP
9.2.4.1 | In this lab you will view the ARP table stored in the router and clear the router's ARP table. These two commands are very important in troubleshooting a network problem.
9.2.4.2 | You and your group have been assigned to help a system administrator of a network for XYZ company. The system administrator of this network would like to know the MAC addresses of each of the Ethernet interfaces on the routers.
Chapter 10: IP Addressing
10.1.4 | In this lab you will work with other group members to design a 5-router network topology and an IP addressing scheme.
10.4.1 | You and your group members have just received your Cisco certification. Your first job is to work with other group members in designing a topology and IP addressing scheme. It will be a 5-router topology similar the standard 5-router lab diagram shown above but with a few changes. Refer to the modified 5-router lab diagram shown in the worksheet. You must come up with a proper IP addressing scheme using multiple Class C addresses which are different from those of the standard lab setup. You will then use ConfigMaker to do your own diagram of the network. You may do this lab using the worksheets or work with the actual lab equipment if it is available.
Chapter 11: Routing
| There are no labs in Chapter 11
Chapter 12: Routing Protocols
12.1.5 | In this lab you will configure a static route between neighboring routers.
12.3.5 | In this lab you will configure RIP as the routing protocol.
12.5.1 | As a system administrator, there will be times where configuring static routes can be very useful. Static routes are useful for stub networks because there is only one way to get to that network. Security is anther reason to use static routes, if you have a network or networks that you don't want the rest of the network to be able to "see" you would not want RIP or other routing protocols sending periodic updates to other routers. With simple networks (few routers) it is sometimes more efficient to use static routes since it conserves bandwidth on WAN links. In this lab you will use static routes for troubleshooting purposes and to see their relationship to dynamic routes and routing protocols.
12.5.2 | In this lab you will setup a WAN connection between Lab-A and Lab-E to create alternate paths in the standard router lab setup. Using a set of WAN serial cables, connect Lab-A Serial 1 to Lab-E Serial 0. Remember to set the clock rate on the DCE side of the cable (Lab-E's Serial 0 interface).
12.5.3 | In the previous challenge lab, you saw how long it took to converge when a link went down. In this lab, your task is to find out how to prevent and control routing loops. The use of hold-down timers, defining a maximum hop count, counting to infinity, poison reverse and split-horizon are all methods of controlling routing loops. You will use the RIP hop count metric to control routing loops in this lab.
Chapter 13: Network Troubleshooting
13.1.6 | For this lab, your instructor will create/introduce multiple problems in the network. You have a limited amount of time in which to find and solve the problems so that you can have the entire network up and running. The tools that you may use for the hardware are in your tool kit. The tools that you may use for the software (IOS) include ping, trace ip route, telnet, and show arp. You may use your Engineering Journal and any Web-based resources (including the curriculum) that are available.
