Page 1 of 3 IT Essentials 5.0 6.3.2.10 Adding Computers to an Existing Network Objectives Configure the computers to use DHCP. Configure Static addressing. Use ipconfig to retrieve host IP information. Use ping to verify connectivity. Hint : To ensure that the instructions always remain visible during an activity, click the Top check box in the lower left-hand corner of this instruction window. Background In this activity, you will configure two computers in the Branch Office network. The company uses DHCP for dynamic addressing of all PCs. Step 1: Study the Topology The topology shows two PCs, a switch, a server, a router, and a cloud. Considering the PCs: a. Notice the PCs are connected to BranchSwitch using straight-through cables. Packet Tracer uses solid lines to represent Ethernet straight-through links. b. Notice the green dots on each side of the straight-through links (next to each PC and next to BranchSwitch ). Green dots on both sides of a link indicate the correct cable type was used to inter- connect those devices. Note : There should be green dots at bot h ends of each cable connection. If you don’t see the green dots navigate to ‘ Options > Preferences’ from Packet Tracer menu and check the ‘ Show Link Lights’ check box. Step 2: Configure DHCP on the PCs a. Click PC0. A PC0 window will appear. b. From the PC0 window, select the Desktop tab. c. Click IP Configuration and select the DHCP button to enable the PC to act as a DHCP client. A DHCP client will receive IP address configuration information dynamically from a DHCP server. (You should see the following message after clicking the DHCP button: DHCP request successful .) d. Close the PC0 configuration window by selecting the x in the upper right-hand corner. e. Click PC1. A PC1 window will appear. f. From the PC1 window, select the Desktop tab. g. Click IP Configuration and select the DHCP button to enable the PC to act as a DHCP client. h. Close the PC1 configuration window.

Page 2 of 3 Step 3: Observe the IP Configuration Information Assigned to Each PC a. Click PC0. b. Select the Desktop tab. c. Click Command Prompt . d. At the PC> prompt, enter the ipconfig /all command. e. Record the IP address, subnet mask, default gateway, and DNS server address information that was dynamically assigned via DHCP to PC0. f. Record the IP address, subnet mask, default gateway, and DNS server address information that was dynamically assigned via DHCP to PC1. g. Using the ping command, test layer 3 connectivity between the PCs and their default router. At the PC0> prompt, enter ping At the PC0> prompt, enter ping At the PC1> prompt, enter ping At the PC1> prompt, enter ping 172.16.1.254 (BranchOffice FastEthernet 0/0 interface IP address) Step 4: Questions As seen in the topology, straight-through cables were originally used to connect PC0 and PC1 to BranchSwitch . If a cross-over cable had been used to connect PC1 to BranchSwitch , answer the following questions: a. In that scenario, would PC1 have acquired an IP address over DHCP? b. Why? c. What about PC0? Would it have acquired an IP address via DHCP if PC1 was connected to BranchSwitch through a cross-over cable? Step 5: Switching to Static Addressing Despite all the benefits of dynamic addressing schemes such as DHCP, sometimes a static scheme is required. Change PC1 from DHCP to static addressing. a. Click PC1 to bring up its configuration window. b. Click the Desktop tab. c. Click IP Configuration . d. Select Static. e. Enter the IP information as follows: IP Address: 172.16.1.20

6.5.1.2 Physical Topologies
Learning Objectives
Familiarize the student with Star, Extended Star, and Mesh physical topologies
Introduction
In this activity, you will build a few different physical topologies using the devices shown. The physical
topologies explored in this activity are:
Star
Extended Star (also known as Hierarchical)
Mesh
Once the devices are cabled in the specified physical topology manner, you will interconnect the topologies.
Task 1: Cable devices in a Star Physical Topology
Step 1. Cabling the first star
a. Locate the following devices: PC00, PC01 , PC02 , PC03 , and SW0. They should be located on the
top- left corner of Packet Tracer’s work area. These devices will comprise a star topology.
b.
From the Connections menu, choose Copper Straight-Through .
Tip: Hold down the as you click the Copper Straight-Through icon to add multiple
connections.
c. Cable the mentioned PCs to SW0. Connect PC00 to SW0’s Fast -Ethernet0/1 , PC01 to SW0’s
Fast-Ethernet0/2 , PC02 SW0’s Fast -Ethernet0/3, and PC03 to SW0’s Fast -Ethernet0/4.
d.
The mentioned devices are now connected in a star topology with SW0 acting as the star’s center.
Task 2: Create the other stars
Step 1. Cabling the second star
a. Locate SW1, PC10 , PC11 , PC12 , and PC13 . These devices should be located in the left-bottom
c
orner of Packet Tracer’s work area.
b.
Similarly to Task 1, cable the second star. From the Connections menu, choose Copper Straight-
Through .
Tip: Hold down the as you click the Copper Straight-Through icon to add multiple
connections.
c. Connect PC10 to SW1’s Fast -Ethernet0/1, PC11 to SW1’s Fast -Ethernet0/2, PC12 SW1’s Fast-
Ethernet0/3 , and PC13 to SW1’s Fast -Ethernet0/4.
d.
The second set of devices should be cabled as a star.

Locate SW2, PC20 , PC21 , PC22 , and PC23. These devices should be located in the center-top area of Packet Tracer’s work area. b. Cable the third star. From the Connections menu, choose Copper Straight-Through . Tip: Hold down the as you click the Copper Straight-Through icon to add multiple connections. c. Connect PC20 to SW2’s Fast -Ethernet0/1 , PC21 to SW2’s Fast -Ethernet0/2, PC22 SW2’s Fast- Ethernet0/3 , and PC23 to SW2’s Fast -Ethernet0/4. d. The third star should now be defined. Step 3. Cabling the fourth star a. Locate SW3, PC30 , PC31 , PC32 , and PC33. These devices should be located in the center-bottom area of Packet Tracer’s work area. b. Cable the fourth star. From the Connections menu, choose Copper Straight-Through . Tip: Hold down the as you click the Copper Straight-Through icon to add multiple connections. c. Connect PC30 to SW3 ’s Fast -Ethernet0/1 , PC31 to SW3 ’s Fast-Ethernet0/2 , PC32 SW3 ’s Fast- Ethernet0/3 , and PC33 to SW3 ’s Fast-Ethernet0/4 . d. The fourth star should now be defined. Star topologies are very useful to contain failures. If SW1’s Fast-Ethernet0/1 fails the only PC10 is affected. A very common design is to place a star at the spoke, creating an Extended Star. Task 3. Creating an Extended Star a. Locate SW0, SW1, SW2, SW3 , and Dist_SW . b. From the Connections menu, choose Copper Cross-Over . c. Connect SW0, SW1, SW2, and SW3 to Dist_SW based on the table below: Devices Switch Port Port on Dist_SW SW0 Fast - Ethernet0/24 Fast - Ethernet0/10 SW1 Fast - Ethernet0/24 Fast - Ethernet0/11 SW2 Fast - Ethernet0/24 Fast - Ethernet0/12 SW3 Fast - Ethernet0/24 Fast - Ethernet0/13 d. You should now have an extended star with 4 smaller stars acting as spokes.
IT Essentials Chapter 6 Packet Tracer/Instructor © 201 4 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public. Page 3 of 4 Task 4. Creating a Full Mesh Topology The biggest flaw with the star topology is the major point of failure it introduces. In even of failure of the device acting as the hub of the star, the entire star fails. In cases where a single point of failure is not accepted, devices are commonly cabled as a full mesh. By cabling each device to all other devices, a redundant topology is created. In this task you will connect the core devices, MainCulster_SW1, MainCulster_SW2 and MainCulster_SW3 as a full mesh by cable each one of them to all others. Because we have 3 devices, each device should have 2 outbound links. Step 1. Interconnecting the core switches. a. Locate MainCluster_SW1 , MainCluster_SW2 , and MainCluster_SW3 . These devices should be located in the right area of Packet Tracer’s work area. b. From the Connections menu, choose Copper Cross-Over . Tip: Hold down the as you click the Copper Cross-Over icon to add multiple connections. c. Interconnect the core devices based on the table below: Source Device Source Port Destination Device Dest ination Port MainCluster_SW1 GigabitEthernet0/1 MainCluster_SW2 GigabitEthernet0/1 MainCluster_SW1 GigabitEthernet0/2 MainCluster_SW3 GigabitEthernet0/1 MainCluster_SW2 GigabitEthernet0/2 MainCluster_SW3 GigabitEthernet0/2 d. With all MainCluster switches now connected to one another, a full mesh is created in between them. Step 2. Create a hybrid topology a. From the Connections menu, choose Copper Cross-Over. b. Connect Fast-Ethernet0/24 of MainCluster_SW1 to Fast-Ethernet0/24 of Dist_SW . By connecting the full mesh topology to the extended star, you create a hybrid topology. c. Packet Tracer should now report 100% completion. Note: If you don’t have 100%, double check the ports used. Packet Tracer is also grading the port choice in this activity. Task 5. Challenge Task Step 1. Analyzing the failure points (and Increasing redundancy) a. How many points of failure can you spot?
