b. What are the networks that are directly connected to the interfaces?
c. What is the clock rate of interface S0 on router Lab-A?
d. What is the password for Telnet lines VTY 0 thru 4?
Step 3 - Examine and document the workstation configurations. (If the workstations have not been configured, skip to step 6).
A. Verify the workstation IP configuration.
Click on Start/Settings and select Control Panel. Double-click on the Network icon. Select the TCP/IP protocol and click the Properties button. For each workstation, click the IP Address tab and record the current settings for the IP address, and Subnet mask in the table below. Click the Gateway tab and record the IP address of the default gateway in the table: (should be the IP address of the E0 router interface that the hub is connected to for each workstation). You may also use the winipcfg.exe utility at the DOS command prompt to verify settings at each workstation.
3. Fill in the IP configuration with information obtained from each workstation.
| Wkstn # | Wkstn. IP addr | Wkstn. Submet mask | Def. Gateway IP addr. |
Step 4 - Test the router lab connectivity.
A. Ping from router to router. Begin with router Lab-A and use the console workstation connection to it. Start the HyperTerminal program and ping the S1 interface of router Lab-B. This will verify that the WAN link between Lab-A and Lab-B is OK. Ping the serial interfaces of the other routers. Lab-A> ping 201.100.11.2
4. Was the ping from router Lab-A to Lab-B successful?
B. Ping from workstation to router. Begin with a workstation connected to the first hub. Click
Start/Programs/MS-DOS Prompt and ping the S1 interface of router Lab-B. This will verify that the
workstation's IP configuration and the WAN link between Lab-A and Lab-B is OK. Ping the serial
interfaces of the other routers. C:\WINDOWS> ping 201.100.11.2
5. Was the ping from router Lab-A to Lab-B successful?
Step 5 - Configure the routers for the standard lab setup (optional).
If the routers need to be configured, refer to the answers section 6 for the steps necessary. You will need to obtain assistance from your instructor or lab assistant.
Step 6 - Configure the workstations for the standard lab setup (optional).
If the workstations need to be configured, refer to the answers section 7 for the steps necessary. You will need to obtain assistance from your instructor or lab assistant.
Step 7 – The OSI model and associated TCP/IP protocol stack layer.
Task: Fill out the following charts based on your knowledge of the OSI model.
Explanation: Your understanding of the OSI model will greatly increase your ability to absorb and categorize networking information as you learn it.
1. List the 7 layers of the OSI model from the top to the bottom. Give a mnemonic word for each layer that can help you remember it and then list the keywords and phrases that describe the characteristics and function of each.
| Layer # | Name | Mnemonic | Key Words and Description of Function |
| 7 | |||
| 6 | |||
| 5 | |||
| 4 | |||
| 3 | |||
| 2 | |||

2. List the 7 layers of the OSI model. Indicate the TCI/IP Protocol Stack layer that is associated with each OSI layer. List the encapsulation unit used to describe the data grouping at each layer.
| Layer # | Name | Encapsulation Unit or Logical Grouping |
