> | Lab 2.2.3.1 Routers - Overview Estimated time: 20 min. Objectives: Setup the Cisco lab equipment according to the semester 2 topology diagram or analyze the physical connections of an existing lab setup. Document the cabling and connections between devices. Draw a diagram of your lab equipment setup. Background: This lab will help you develop an understanding of how the Cisco lab routers are set up and connected for the Semester 2 topology (see diagram on previous page). You will examine and document the physical connections between these routers and the other lab hardware components such as hubs, switches, and workstations. This lab will utilize the standard setup consisting of 5 routers, 4 hubs, 1 switch, and at least 5 workstations plus all associated cabling and adapters. The next lab 2.2.3.2 will give you an opportunity to document the IP addressing and internal IOS configuration of the routers if the are already configured. If they are not configured, instructions will be provided to configure and test them. Tools / Preparation: Prior to starting this lab you will need to have the equipment from the standard 5-router lab available (routers, hubs, switch, etc.). The routers and hubs should be disconnected and stacked. Each cabling type (WAN, LAN, console, power) should be grouped together. If it is not possible to start with equipment disconnected, you should review the steps of the lab with the equipment already connected. This will familiarize you with the physical connections and device interfaces. The routers may be pre-configured by the instructor or lab assistant with the correct IP interface settings etc. The workstations may also be pre-configured to have the correct IP address settings prior to starting the lab. The routers and workstations should be labeled as indicated in this lab. Start with the routers, switches, hubs, and cabling disconnected if possible. Your team will need to connect them according to the topology diagram in the overview at the beginning of this lab and then document your findings. This lab requires that you assemble the routers into the standard lab topology or as close as possible depending on the equipment you have. Work in teams of 3 or more. Before beginning this lab you may want to review Chapters 3 and 4 in the Cisco Networking Academy First-Year Companion Guide and Semester 2 On-line Chapter 2. The following resources will be required: 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.

When setting up the lab equipment from scratch you will need to give some thought to the questions listed below. Even if you are starting with an existing assembled lab setup, you should review all steps and answer all questions to become more familiar with how the routers are connected. Even though you may not be actually connecting the equipment, you should locate, examine and document the cabling and physical connections between routers, hubs and workstations. Where should the PC's be placed? Where should the routers be placed? Where should the switch and hubs be placed? How should the Ethernet, serial and power cables be run? How many outlets and power strips will be needed? Which PC connects to which router? · Which PC connects to which hub or switch? Which Router connects to which hub or switch? How should devices and cabling be labeled? Step 2 - Arrange Lab Equipment. Your arrangement of the routers and equipment will vary depending on space and physical setup of your lab area. The goal is to group each combination of router/hub/workstation closely together since they can represent separate LANs and geographical locations in the real world. It is easier to see the relationships between equipment with this arrangement. Equipment should be positioned so that all interfaces are facing the same direction and so that cabling and connections can be accessed easily. A. Table or work surface setup - If you are setting the routers out over tables or desks, place the labeled routers side by side in order from left to right (Lab-A, Lab-B…). Place the switch on top of router Lab-A. Place hub 1 on top of the switch and hubs 2, 3 and 4 on top of routers B, C and D. Place router Lab-D with its hub on top of Lab-E since they are connected to the same LAN. Workstations should be located close to or on the tables for the routers and hubs to which they connect. B. Single rack setup - If you have a single 19" network equipment rack, mount the first router, Lab-A up high in the rack and mount the switch just above it. Mount the other routers in the rack in sequence from top to bottom with about 4 to 6 inches between each router. Place a hub on top of the switch above router Lab-A and on top of routers B, C and D. Workstations should be spread out around the rack to allow workspace and will be numbered from left to right. C. Multiple rack setup - If you have multiple racks, put a router and hub in each rack from top to bottom and left to right depending on how many racks you have. Place workstations as close to the routers as possible while still allowing workspace. Step 3 - Connect Serial WAN Cabling. Next you will connect serial cables (DCE-DTE) between routers. With this lab setup, the router interface serial 0 (S0) is connected to the DCE cable. DCE refers to Data Circuit-Terminating Equipment (or Data Communications Equipment) connections and represents the clocking end of the synchronous WAN link. The DCE cable has a large female V.35 (34-pin) connector on one end and a DB-60 connector on the other end which attaches to the router serial interface. Interface serial 1 (S1) is connected to the DTE (Data Terminal Equipment) cable. The DTE cable has a large male V.35 connector on one end and a DB60 on the other end which attaches to the router serial interface. Cables are also labeled as DCE or DTE. 1. Examine the cables and connections on the routers and document the connections in the table:
> From Router Name | Interface | To Router Name | Interface
> Step 4 - Connect the Router Ethernet Cabling. For routers that have an AUI (Attachment Unit Interface) Ethernet 0 (E0) or E1 port, you will need an external transceiver which converts the DB15 AUI to an RJ45 10BASE-T connector. The 2500 series routers usually have an AUI port. The 1600 series has both AUI and RJ45 ports and you can use the RJ45 port without the need for the external transceiver. All Ethernet cabling from routers to hubs or switches must be Category 5 (Cat 5) and wired "straight-thru" (pin 1 to pin 1, pin2 to pin 2 etc.). Connect the Ethernet cabling as indicated in the diagram and then label the cabling at each end. Hubs should be numbered Hub 1, Hub 2, etc. 2. Record the router Ethernet interfaces in use and which hub (or switch) they attach to in the table:
> From Router Name | Router Interface | To which Ethernet Device
> Lab-A |  |
> Lab-B |  |
> Lab-C |  |
> Lab-D |  |
> Lab-E |  |
> Lab-F |  |
> Step 5 - Connect the Workstation Ethernet Cabling. Place the PC's at their planned locations and label them (WS-1, WS-2…) from left to right according to the diagram. Run straight-through CAT 5 cables from each PC to where the switch and hubs are located. Connect the Ethernet cabling as indicated and then label the cables at each end depending on what device and interface they connect to. The following table shows the connections for all 10 workstations. Connect at least one workstation to each hub or switch. 3. Indicated which Ethernet device each workstation connects to in the table below:
> From Workstation | To which Ethernet Device
> WS-1 |
> WS-2 |
> WS-3 |
> WS-4 |
> WS-5 |
> WS-6 |
> WS-7 |
> WS-8 |
> WS-9 |
> WS-10 |
> Step 6 - Connect the Console Workstations to Routers. Connect one end of the rollover cables from workstations 4, 6, 8, 9, and 10 to the console interface of routers Lab-A, B, C, D and E. Connect the other end of each of the rollover cables to an RJ-45-to-DB-9 serial connector. Connect the serial connector to the serial ports of the 5 workstations. Label the cables at each end. 4. What type of cable is the console cable? Step 7 - Connect Power Cords to All Devices. Plug in and turn on all devices. Verify all of them are activated by checking their indicator lights. 5. Are the link lights for the switch, the hubs and the Network Interface Cards (NICs) in the workstations on? Are the OK lights on the back of the routers on? Step 8 - Draw your lab diagram. In the space provided below or in your engineering journal redraw the router lab diagram to match your physical setup. Label all LAN (Ethernet) and WAN (serial) interfaces and cabling.
