This PC- based product simulates a wide variety of Cisco routers as well as the Catalyst 1900, 2950, and 5000 switches. The NetSim supports multiple routing protocols, including RIP, IGRP, EIGRP, and single-area OSPF. It supports different LAN/WAN protocols, including PPP/CHAP, ISDN, and Frame Relay. The exercises in this lab guide only require the NetSim – they do not require access to any external router or switch hardware. It should be noted that the NetSim supports many, but not all of the IOS commands available on a real router or switch. All the commands referenced in this lab guide are supported through the Simulator. Getting Started To 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 representing each 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 accessed by pressing the More Devices button. There is also a button that can be pressed to show the network topology that the labs are based on. Lab Topology The 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 routers o each router has one Ethernet and two serial interfaces o one of the 2500’s, router1, has an ISDN BRI interface • 1 x Cisco 2600 router (identified as router2) o has one Ethernet interface o has both an ISDN BRI and a PRI interface • 2 x Catalyst 1912 switches o each switch has twelve 10baseT and two Fast Ethernet ports Copyright (c) 1998-2004 Boson Software, Inc. All Rights Reserved. • 2 X Catalyst 2950 switches o each switch has twelve 10/100 Ethernet ports • 2 x PC’s The LAN/WAN interfaces and subnet numbers are indicated on the diagram. Specific interface IP addresses are included in a table on page 6. LAB TOPOLOGY Copyright (c) 1998-2004 Boson Software, Inc. All Rights Reserved.

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 Relay There 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 labs sequentially. You will also be asked questions at various points during the lab. Answers to these questions are contained in Appendix B at the back of this lab guide. Appendix C also contains the completed configurations for selected labs. Saving/Restoring Configuration Files You can save your work and exit at any point. First, make sure you have selected the appropriate router/switch/PC button at the top of the NetSim screen. 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 appropriate router/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 saved configuration 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.
