6.1.2.1 Packet Tracer – Add Computers to an Existing Network Instructions

Packet Tracer – Add Computers to an Existing Network

Objectives

  • Configure the computers to use DHCP
  • Configure static addressing on the server
  • 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.

Introduction

In this activity, you will investigate the topology, configure DHCP and static addressing, and use commands to verify addressing and test connectivity.

Instructions

Step 1: Study the Topology.

The topology shows two PCs, a switch, a server, a router, and a cloud.

a. Notice the PCs are connected to BranchSwitch using straight-through cables.

b. Notice the green triangles on each side of the straight-through links (next to each PC and next to BranchSwitch). Green triangles on both sides of a link indicate the correct cable type was used to connect those devices.

Note: There should be green triangles at both ends of each cable connection. If you do not see the green triangles 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.

b. In the PC0 window, select the Desktop tab.

c. Click IP Configuration and select DHCP to enable the PC to act as a DHCP client. 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. Repeat steps 2a – 2d for PC1.

Step 3: Observe the IP Configuration Information Assigned to Each PC.

a. Click PC0. Click the Desktop tab.

b. Click Command Prompt. At the PC> prompt, enter the ipconfig /all command. Press the space bar to see all the output.

c. Record the IP address, subnet mask, default gateway, and DNS server address information that was dynamically assigned via DHCP to PC0.

d. Repeat steps 3a – 3c for PC1.

e. Using the ping command, test connectivity between the PCs and the default gateway (BranchOffice FastEthernet 0/0 interface IP address).

  1. At the PC0> prompt, enter ping PC1’s IP address.
  2. At the PC0> prompt, enter ping default gateway IP address.
  3. At the PC1> prompt, enter ping PC0’s IP address.
  4. At the PC1> prompt, enter ping default gateway IP address.

Step 4: Switch to Static Addressing.

Despite all the benefits of dynamic addressing schemes such as DHCP, sometimes a static scheme is required. Configure Server0 to use static addressing.

a. Click Server0 to open the configuration window.

b. Click the Desktop tab. Click IP Configuration.

c. Verify that it is using static IP addressing.

Enter the IP information as follows:

IP Address: 172.16.1.100
Subnet Mask: 255.255.255.0
Default Gateway: 172.16.1.254
DNS: 209.165.200.226

d. Server0 is now configured with a static address. Close IP Configuration.

e. Click PC1 to open its configuration window.

f. In the command prompt, ping Server0. The pings should be successful.

Check your score. It should be 100%.
