ThisPC-based product simulates a wide variety of Cisco routers as well as theCatalyst 1900, 2950, and 5000 switches. The NetSim supports multiple routingprotocols, including RIP, IGRP, EIGRP, and single-area OSPF. It supportsdifferent LAN/WAN protocols, including PPP/CHAP, ISDN, and Frame Relay.The exercises in this lab guide only require the NetSim they do not requireaccess to any external router or switch hardware.It should be noted that the NetSim supports many, but not all of the IOScommands available on a real router or switch. All the commands referenced inthis lab guide are supported through the Simulator.Getting StartedTo invoke the NetSim, double-click on the Boson NetSim icon on your PC screen. If there is not an icon on the PC screen, you can start the NetSim by pressing Start -> Boson NetSim -> Boson NetSim.You will be presented with a screen that has buttons at the top representingeach router, switch, or PC that you will be configuring.Press one of the buttons to configure a device. Some of the devices are hidden(Switch 3, Switch 4, PC1, and PC2) and can be accessedby pressing the More Devices button. There is also a button that can be pressedto show the network topology that the labs are based on. Lab TopologyThe Lab Topology is shown in the diagram on the next page (it can also be viewed by selecting the Topology button at the top of the NetSim screen).You will have:4 x Cisco 2500 routerseach router has one Ethernet and two serial interfacesone of the 2500 s, router1, has an ISDN BRI interface1 x Cisco 2600 router (identified as router2)has one Ethernet interfacehas both an ISDN BRI and a PRI interface2 x Catalyst 1912 switcheseach switch has twelve 10baseT and two Fast Ethernet ports2 X Catalyst 2950 switcheseach switch has twelve 10/100 Ethernet ports2 x PC sThe LAN/WAN interfaces and subnet numbers are indicated on the diagram.Specific interface IP addresses are included in a table on page 6.

They include: Lab 1 - Basic Router Configuration Lab 2 - Advanced Router Configuration Lab 3 - CDP Lab 4 - Telnet Lab 5 - TFTP Lab 6 - RIP Lab 7 - IGRP Lab 8 - EIGRP Lab 9 - OSPF Lab 10 Catalyst 1900 Switch Configuration Lab 11 - VLANs & Trunking (Catalyst 1900) Lab 12 - Catalyst 2950 Switch Configuration Lab 13 - VLANs and Trunking (Catalyst 2950) Lab 14 - IP Access Lists Lab 15 - NAT/PAT Lab 16 - PPP & CHAP Lab 17 - ISDN BRI-BRI using Legacy DDR Lab 18 - ISDN BRI-BRI using Dialer Profiles Lab 19 - ISDN PRI using Dialer Profiles Lab 20 - Frame RelayThere is also an optional IPX lab contained in Appendix A of this lab guide.These labs build upon each other so the best approach is to follow the labssequentially. You will also be asked questions at various points during thelab. Answers to these questions are contained in Appendix B at the back of this lab guide. Appendix C also contains the completed configurations for selectedlabs.Saving/Restoring Configuration FilesYou can save your work and exit at any point. First, make sure you haveselected the appropriate router/switch/PC button at the top of the NetSimscreen.The next step is to press File -> Save Device Config from the top of the screen. You will then be prompted for a file name.Each individual device configuration must be saved separately. At a minimum,you should plan to save all configurations each time you power off your PC. To restore a configuration file, make sure you have pressed the appropriaterouter/switch/PC button. The next step is to press File -> Load Device Config (Overwrite) at the top of the screen and to select the correct savedconfiguration file. The configuration will then be loaded.Note: this process can take 15-20 seconds to complete and you will see configuration commands flash across the screen. Be patient! LAB 1 BASIC ROUTER CONFIGURATION1. In this lab, you will get practice with basic configuration and show commands on the Cisco router.2. Select Router1 from the tool bar. Press enter to get to the user promptRouter>3. The greater-than symbol ( >) in the prompt indicates you are in user mode.Type ? to see a list of commands that can be entered in user mode. Router> ?4. Type enable to get into privileged mode. The pound sign (#) indicates youare now in privileged mode.Router> enableRouter#5. Type ? to see a list of commands that can be entered in privileged mode.Notice that there are more commands available inprivileged mode than are available in user mode. Configure and reload are twosuch commands that can only be issued in privileged mode.Router# ?6. Exit privileged mode by typing disable.Router# disableRouter>7. Re-enter privileged mode and type configure terminal to get intoconfiguration modeRouter> enableRouter# configure terminalRouter(config)#8. Configure a hostname of router1 (without the quote marks). Notice how theprompt changes.Router(config)# hostname router1router1(config)#9. In global configuration mode on router1, type enable ?. This will show valid parameters that can be entered with the enable command.Configure an enable password of ccnalab that will not be encrypted whenviewing the router configuration file and an enablepassword of cisco that will be encrypted.a. Question: when both encrypted and unencrypted enable passwords areconfigured, which one is used?router1(config)# enable ?router1(config)# enable password ccnalabrouter1(config)# enable secret cisco10. Configure an IP address for the Ethernet0 interface on router1 (refer to the table on page 6 for all IP addresses and masks).Activate the interface it is currently in shutdown mode. You should see a
