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 add two computers to the Branch Office network. The company uses DHCP for dynamic addressing of all PCs. Step 1: Study the Topology
The topology shows 2 PCs, a switch, a server, a router, and a cloud. Considering the PCs:
a. Notice the PCs are connected to BranchSwitch through 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 both 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. 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 <PC1’s IP address>
At the PC0> prompt, enter ping <router’s IP address>
At the PC1> prompt, enter ping <PC0’s IP address>
At the PC1> prompt, enter ping <router’s IP address> Step 4: Questions
As seen in the topology, straight-through cables were originally used to connect PC0 and PC1 to
