Identify the three layers of a hierarchical network and how they are used in network design.
Instructor Note: This activity can be completed individually or in small groups.
A network administrator is tasked with designing an expanded network for the company.
After speaking with network administrators in other branches of the company, it was decided to use the Cisco three-layer hierarchical network design model to guide the expansion. This model was chosen for its simple influence upon network planning.
The three layers of the expanded network design include:
Access
Distribution
Core
World Wide Web access
Presentation software
a. Find two images that show the three-layer hierarchical design model.
b. Note the online image’s web address.
a. Notice the types of equipment in each layer of the designs you have chosen.
b. Differentiate why it is assumed the types of equipment shown in the images are located where they are on the design.
c. Notice any other differences between the chosen images.
Number of devices used within the layers
Redundancy, if any
a. The two chosen designs with hyperlinks as to their Internet site locations.
b. A statement on each slide as to why the particular image was chosen.
c. Comparison statements as to how the two images differ, but with an explanation of why they are classified as three-level hierarchical designs.
Design Hierarchy
Student or Group Notes as to why this graphic was chosen:
Access layer shows PCs, access switches, VPN gateways, printers, teleworker, home office, and wireless router. Also shown in this layer are redundant links to the distribution layer.
The distribution layer shows several multilayer switches and link connections to the core layer.
The core layer shows multilayer switches and connections to the distribution layer and the cloud.
Basic equipment types are located in the access layer, closest to the user and work with the distribution layer
above it. Most of the network devices are located at this level on both images.
The distribution layer equipment interfaces with both core and access layers in both images. This hierarchical
level seems to contain the most sophisticated and multifunctional equipment. Redundancy is clearly apparent to both core and access layers as shown in the first model. It would seem that high-powered multifunction
Design Hierarchy
switches would be located at this level of the two graphics. The number of network devices shown in both graphics at this level is smaller than the access layer, but larger than the core layer.
As shown in the two previous graphics, the core layer has the most sophisticated equipment. There are fewer
network devices at this layer, which seems to indicate that the devices are highly functioning and fast traffic processors.

Part 1: Investigate Dedicated WAN Technologies and Providers
Part 2: Investigate a Dedicated Leased Line Service Provider in Your Area
Today’s broadband Internet services are fast, affordable, and secure using VPN technologies. However, many companies still find the need for a 24-hour dedicated connection to the Internet or a dedicated point-to- point connection from one office location to another. In this lab, you will investigate the cost and availability of purchasing a dedicated T1 Internet connection for your home or business.
Device with Internet access
Part 1: Investigate Dedicated WAN Technologies and Providers
In Part 1, you will research basic characteristics of dedicated WAN technologies, and in Step 2, you will discover providers that offer dedicated WAN services.
Use search engines and websites to research the following WAN technologies to complete the table below.

Navigate to http://www.telarus.com/carriers.html. This webpage lists the Internet service providers (also known as carriers) that partner with Telarus to provide automated real-time telecom pricing. Click the links to the various carrier partners and search for the dedicated WAN technologies that they provide. Complete the table below by identifying each service provider’s dedicated WAN services, based on the information provided on the website. Use the extra lines provided in the table to record additional service providers.
Lab – Researching WAN Technologies
Choose Internet T1 (1.5 MB) and scroll down to Step 3 on the webpage.
Lab – Researching WAN Technologies
a. In the Installation BTN field, enter your sample business telephone number. This should be a landline number.
b. Enter your address, city, state, and zip code.
a. Do not click the first radio button ( Please call me ASAP at ), but do provide your contact telephone number.
b. Click the I am just window shopping radio button.
c. Click Continue.
You should see a list of quotes showing the available pricing of a T1 connection to the location you specified. Was the pricing in the area you chose comparable to those pictured below?
Answers will vary depending on service location and availability.
What was the range of prices from your results?
Answers will vary depending on service location and availability.

Select WAN access technologies to satisfy business requirements in a small-to-medium-sized business network.
Instructor Note: This activity can be completed individually or in small groups – it can then be shared and discussed with another group of students, with the entire class, or with the instructor.
Your medium-sized company is upgrading its network. To make the most of the equipment currently in use, you decide to purchase WAN modules instead of new equipment.
All branch offices use either Cisco 1900 or 2911 series ISRs. You will be updating these routers in several locations. Each branch has its own ISP requirements to consider.
To update the devices, focus on the following WAN modules access types:
World Wide Web
Word processing software
Note: If the above link is no longer valid, search the Cisco site for “Interfaces and Modules”.
Ethernet
Broadband
T1/E1 and ISDN PRI
BRI
Serial WAN
WAN Device Modules
T1 and E1Trunk Voice and WAN
Wireless LANs and WANs
Instructor Notes:
This is a good place to have students discuss the terminology. For instance, WIC2T = WAN Interface Card with 2 serial ports.
Students can also add various cards to routers in PT and use commands such as show ip interface brief to view the changes.
Please encourage students to read the datasheet information listed on the modular card graphics sites – they will become familiar with different interface types by doing so.
All graphics will vary as shown in the students’ final matrix – the graphics shown in this Activity Example Solution are representative in nature and were copied from the Cisco products sites. Each graphic is hyperlinked to the source available at the time this activity was created.
