Designing and Supporting Computer Networks
StadiumCompany Story
The Discovery “Designing and Supporting Computer Networks” course uses the fictional StadiumCompany
network upgrade story in the main text and media presentation and in Packet Tracer activities. StadiumCompany
is a stadium management company that manages a large sports facility.
When the sports facility was built, the network that supported its business offices and security services provided
state-of-the-art communications capabilities. Over the years, the company added new equipment and increased
the number of connections without considering the overall business goals and long-term infrastructure design.
Some projects went ahead without an understanding of the bandwidth, traffic prioritization, and other
requirements needed to support this advanced and business-critical network. Now the StadiumCompany
management wants to improve the customer experience by adding high-tech features and support for concerts,
but the underlying network cannot support these additions.
The StadiumCompany management understands that they do not have sufficient network expertise to support the
network upgrade. The StadiumCompany decides to hire network consultants to provide design, project
management, and implementation support. The project will be implemented in three phases. The first phase is to
plan the project and prepare the high-level network design. The second phase is to develop the detailed network
design. The third phase is to implement the design.
After a few meetings, StadiumCompany hires the NetworkingCompany, a local network design and consulting
firm to support the phase 1, high-level design. NetworkingCompany is a Cisco Premier Partner employing 20
network engineers who have various CCNA, CCDA, CCNP, CCDP, and CCIE certifications and significant
industry experience.
To create the high-level design, the NetworkingCompany first interviewed the staff at the stadium and developed
a profile of the organization and the facility.

• 35 managers and executives
• 135 salaried personnel
Approximately 80 additional hourly workers are hired as needed to support events in the facility and security
departments.
Stadium
Management
Offices
StadiumCompany Phones and PCs
All the managers and executives at the StadiumCompany use PCs and phones connected to a digital voice PBX.
With the exception of the full-time grounds people and the janitors, all the salaried personnel also use PCs and
phones.
Fifty shared phones for the security staff are distributed throughout the stadium. There are also 12 analog
phones, some that support faxes and others that provide direct access to the police and fire stations. The security
group also has 30 security cameras implemented on a separate network.
Existing Facilities and Support
The StadiumCompany provides facilities and network support for two sports teams (Team A and Team B), a
visiting team, a restaurant, and a concessions vendor.

CCNA Discovery
The stadium is approximately 725 feet wide by 900 feet long (approximately 220 meters wide by 375 meters
long). There are two levels. Because of the size of the facility, multiple wiring closets connected with fiber-optic
cabling are distributed throughout the stadium.
The Team A and Team B locker rooms and player lounges are on the first level of the south side of the stadium.
The team offices are on the second level and measure 50 feet x 200 feet (approximately 15 meters wide by 60
meters long)
The office and locker room of the visiting team are also located on the first level.
StadiumCompany offices are in the north side of the stadium on both levels. The office space on the first level
measures 200 feet x 60 feet (approximately 60 meters wide by 18 meters long), and measures 200 feet x 50 feet
(approximately 60 meters wide by 15 meters long) on the second level.
Team A and Team B are in different sports leagues with different seasons. They both contract with the
StadiumCompany for offices and services at the stadium.
Team A Organization
Team A has 90 people in the organization:
• 4 executives
• 12 coaches
• 14 support staff (including doctors, masseuse, secretary, assistants, finance and accounting)
• 60 players
Team A has 15 offices in the stadium to support their non-player staff. Five of these offices are shared. There are
24 PCs and 28 phones installed in the offices.
Team A also has a player locker room and a large player lounge and workout room. The non-player staff uses the
facility year round. Players have access to the locker room and workout equipment both during the season and

CCNA Discovery
the off-season. There are 5 phones in the locker room, and 15 phones in the player lounge. There are rumors that
Team A recently installed a wireless hub in the player lounge.
Team B Organization
Team B has 64 people in the organization:
• 4 executives
• 8 coaches
• 12 support staff (including doctors, masseuse, secretary, assistants, finance and accounting)
• 40 players
Team B has 12 offices in the stadium to support their non-player staff. Three of the offices are shared. There are
19 PCs and 22 phones installed in the offices. They also have a player locker room and a large player lounge.
The non-player staff uses the facility year round. Players have access to the locker room and workout equipment
both during the season and the off season. There are 5 phones in the locker room, and 15 phones in the player
lounge.
Visiting Team Support
The visiting team locker room and lounge has 10 phones. Each visiting team requires temporary support on the
game day and for a few days before the game. The visiting teams also contract with the StadiumCompany for
office support and services at the stadium.
Concession Vendor
A concession vendor manages the concessions provided at games and events. There are five full-time
employees. They use two private and two shared offices with five PCs and seven phones. These offices are
located on the south side of the stadium between the Team A and Team B office space. Two part-time employees
take orders from the luxury boxes during events. The concession vendor uses seasonal hourly workers to support
32 permanent concession stands and other services distributed throughout the stadium. At this time, there are no
phones or PCs in the concession areas.
Luxury Restaurant Organization
There is one luxury restaurant at the stadium that is open year round. In addition to the customer and kitchen
areas, the restaurant contracts for office space from the StadiumCompany. The four managers have private
offices. The two salaried financial and accounting staff share an office. Six PCs and phones are supported. Two
additional phones are used for reservations in the customer area.

CCNA Discovery
Luxury Skybox Support
There are 20 luxury skyboxes. The StadiumCompany provides a phone in each skybox that supports local calls
and calls to the luxury restaurant and the concession vendor.
Press Area Support
The StadiumCompany provides a press box with three shared areas:
• The press print area typically houses 40 to 50 reporters during a game. There are 10 analog phones available
in this shared area, and two shared data ports. It is known that one newspaper intern brings in a small
wireless Access Point for games that she covers.
• The press radio area supports 15 to 20 radio announcers and has 10 analog phone lines.
• The press TV area typically supports 10 people. There are five phones available here.
Remote Site Support
The StadiumCompany currently has two remote locations: a ticketing office located in the downtown area, and a
souvenir shop in a local shopping mall. The remote locations are connected using DSL service to a local Internet
service provider (ISP).

CCNA Discovery
The stadium is connected to the local ISP using ISP1, a managed services router owned by the ISP. The two
remote sites have a connection to the same ISP supported by the ISP2 and ISP3 routers provisioned and
managed by the ISP. This connection provides the remote sites access to the databases located on servers in the
StadiumCompany management offices. The StadiumCompany also has a perimeter router named Edge Router
that connects to the ISP1 router at the stadium.
StadiumCompany Plans
The StadiumCompany wants to add new services, such as video, to their network. They are also thinking about
replacing the existing digital voice PBX. They would like better access to their existing security camera network.
Two new remote sites are planned in the near future:
• A film production company that has been hired to provide video during and after the sporting events and
concerts needs to connect to the stadium network to exchange files.
• Team A is expanding to a remote office location. They are requesting access to the same network resources
that they use on the stadium LAN.

1.3.2 Investigating Failure Domains
Objective
a. Observe the flow of network traffic in different topologies
b. Observe the change of flow in network traffic when a point of failure is introduced into the network
This activity has three different topologies: a partial mesh, a star, and a full mesh. When this activity is started,
you will need to allow time for each network topology to converge. This may take several minutes. Once
the networks have converged, you will note the following:
a. The partial mesh topology will have one link light on the PM4 switch that remains amber.
b. The star topology will have all the link lights green.
c. The full mesh topology will have three link lights amber; one on the FM1 switch and two on the FM3
switch.
Required file: Investigating Failure Domains.pka
In the partial mesh and full mesh topology the network has redundant links. However, in order to avoid switching
loops some of the links have been shutdown as noted by the amber link light. Note that the star topology does not

CCNA Discovery
have redundant links between switches. Why are all of the link lights green in this topology?
___________________________________________________________________________
Good Distribution Layer design can limit the parts of the network that are affected by a network failure. The failure
of a single device should not cause the network to go down. In this activity you will observe the flow of the
network traffic in each topology. Then you will introduce a point of failure in each network topology by deleting a
trunk link between two switches. Once the link is removed, you will need to allow time for the network to re-
converge. After the network has re-converged, you will again observe the flow of traffic and note how the network
failure affected the flow of traffic.
Step 1: Observe the flow of traffic on the partial mesh topology
a. Once the network has converged, enter simulation mode by clicking on the Simulation tab.
b. By default, Scenario 0 should be displayed in the Scenario window. Click on the Auto Capture/Play
button and observe the flow of traffic from PM3B to PM4B
c. When the Buffer Full window appears, click Clear Event List.
d. Click the Reset Simulation button
Step 2: Introduce a point of failure on the partial mesh topology
a. Delete the trunk link between PM2 and PM4
b. Change to simulation mode by clicking on the Simulation tab.
c. Play Scenario 0 again by clicking on the Auto Capture/ Play button and observe the flow of traffic from
PMB to PM4B
d. When the Buffer Full window appears, click Clear Event List.
e. Click the Reset Simulation button
Step 3: Observe the flow of traffic on the star topology
a. Click on the dropdown arrow to the Scenario window and select Scenario 1.
b. Play Scenario 1 by clicking on the Auto Capture/ Play button and observe the flow of traffic from S2A to
S4B
c. Click Clear event List when the Buffer Full window appears and click the Reset Simulation button
Step 4: Introduce a point of failure on the star topology
a. Delete the trunk link between Star1 and Star2
b. Since the star topology has no redundant links, the network will not need to re-converge
c. Play Scenario 1 again and observe the flow of traffic from S2A to S4B
d. Click Clear event List when the Buffer Full window appears and click the Reset Simulation button
Step 5: Observe the flow of traffic on the full mesh topology
a. Click on the dropdown arrow to the Scenario window and select Scenario 2
b. Play Scenario 2 by clicking the Auto Capture / Play button and observe the flow of traffic from FM1A to
FM3B
c. Click Clear event List when the Buffer Full window appears and click the Reset Simulation button
Step 6: Introduce a point of failure on the full mesh topology
a. Delete the trunk link between FM2 and FM3
b. Switch to the Realtime mode
c. Allow time for the network to converge. (This may take several minutes.)
d. Play Scenario 2 again and observe the flow of traffic from FM1A to FM3B
e. Click Clear event List when the Buffer Full window appears and click the Reset Simulation button

1.3.4 Placing ACLs
Objectives
• Verify network connectivity
• Examine the Access Control Lists (ACLs) that are configured on the routers
• Determine the appropriate interface to apply the ACLs
• Examine the affects of the ACL

CCNA Discovery
This activity demonstrates how the flow of network traffic is affected by applying an ACL to permit or deny traffic in
the network. The network administrator has decided that all external web traffic goes only to the Web server.
Also, in order to protect the data o their employees, the HR server is only accessible to HR employees.
Therefore, ACLs will need to be implemented on the network. Another network technician has already configured
the necessary ACLs on both the Gateway and Distribution2 routers. However, the ACLs have not been applied to
an interface. You have been asked to apply the ACLs and verify that the appropriate traffic is permitted or denied.

a. Access the Distribution1 router. Use the following commands to view the ACL that has been configured
on the Distribution1 router:
• show running-config
• show access-lists 1
b. Access the Gateway router. Use the following commands to view the ACL that has been configured on
the Gateway router:
Step 3: Determine the appropriate interface to apply the ACLs
a. After examining the ACLs determine on which interface the ACLs should be applied
b. The ACL must be applied to an interface or subinterface before it will affect the network traffic
c. The extended ACL should be placed closest to the source and the standard ACL should be closest to the
destination.
d. Remember that only one ACL per port, per protocol, per direction is allowed.
e. Apply the ACL to the appropriate interface or subinterface.
Step 4: Examine the affects of the ACL
a. Internet Host should be able to ping any device in the network, except HR1 or HR server.
b. Internet Host should be able to access Web server (192.168.0.3) using the browser.
c. Internet Host should not be able to access either the HR server (192.168.40.1) or Sales server
(192.168.10.2) using the browser.
d. HR2 should be able to access HR server (192.168.40.1) using ping or the browser.
e. RandD2 should not be able to access HR server (192.168.40.1) using ping or the browser.

1.5.3 Using Redundant Links on Server Farm Devices
Objective
• Determine how redundancy affects server availability.
The physical topology of the first network (Topology 1) has been designed without redundancy. To test the fault
tolerance of the network, links should be removed to test the effect on the network and to determine if the network
can recover from the removed link.
The physical topology of the second network (Topology 2) has been designed and redundancy has been
incorporated into the design. To test the fault tolerance of the network, links should be removed to test the effect
on the network and to determine if the network can recover from the downed link.

3.1.1 Investigating Existing Network Devices
Objective
• Use router and switch commands to obtain information about an existing network.
You have been given the task of documenting a large campus network. When you arrive at the site you
discover that the network administrator is not available and he has the only keys to the wiring closets and the
cabinets containing the existing network documentation. Since information on the network is needed as soon
as possible, you decide to discover as much information as possible using router and switch commands.
You are given access to the administrator’s PC and are told that the Telnet access password for all devices is
cisco and the password to enter privileged exec mode is class.
Step 1: Discover and document the first device.
a. Access the Admin PC and issue the ipconfig command from the command prompt to discover the
default gateway.
b. Telnet to the IP address of the gateway device and enter privileged exec mode using the passwords
given above.
c. Issue IOS commands such as show running-config, show ip route, show interfaces, show ip
interface brief, show version and other commands to learn about the device.
d. Issue IOS commands such as show cdp neighbors and show cdp neighbors detail to discover
information about connected devices. It may take a few minutes for the network to converge. If you do
not see any neighboring devices initially, repeat the command until you do.
e. Document the information you gather in the appropriate table below.
f. Close the Telnet session by issuing the exit command.
Step 2: Discover the remaining devices.
a. Packet Tracer works best when you successfully ping a device before attempting to Telnet to it.
Issue the ping command to the IP address of one of the devices you discovered in Step 1. Repeat
the ping command until it succeeds.
b. Telnet to the IP address of the device and repeat the process in Step 1 to document the device.
c. To not overuse the resources of Packet Tracer, do not Telnet from device to device. Always exit to
the command prompt before accessing the next device.
d. Repeat the process until all devices in the network are discovered and documented.

Equipment installed at the Network Distribution Layer usually consists of multi-layer, modular switches that
connect to Layer 2 Access Layer switches through redundant links. These Distribution Layer switches then
connect to Core Layer devices, also through redundant links. Spanning Tree Protocol allows these redundant
connections without the problems associated with switching loops.
Packet Tracer only supports devices typically found in the CCNA academy lab bundle, not the type of
switches typically used at the Network Distribution Layer. We will use regular Layer 2 switches to represent
these switches as we connect the redundant links between the Access and Distribution Layer switches and
observe the operation of Spanning Tree Protocol.

5.5.3 Implementing Access Control Lists
Objective
• Test basic connectivity
• Create and apply an Access Control List (ACL)
• Verify the application of the ACL
As part of an IT staff, you have been asked to work with the network designer to define the firewall rule set to
be implemented in the new network design. The firewall rule set dictates the exact types of network activity
permitted. As the designer of a network, you are responsible for the first line of security on the network. The
security policies will dictate which users and groups are permitted access to what resources, and what type of
access is denied. When designing firewall rule sets and access control lists, the general policy is to deny all
traffic that is either not specifically authorized or is not in response to a permitted inquiry. Each firewall rule set
may require more than one ACL statement and may require both inbound and outbound placement. In this
scenario, you will be creating a sampling of ACLs that might be applied in a firewall rule set.
Required file: Implementing Access Control Lists.pka
Step 1: Discover and document the first device.
a. Access the Admin PC and issue the ipconfig command from the command prompt to discover the

• Disable auto-summarization in RIPv2.
• Test and verify full connectivity
In this lab activity, you will be given a preconfigured topology with discontiguous subnetworks. The routers are
configured with RIPv2 and auto-summarization is running by default. The discontiguous networks are each of
the three LANs separated by the WAN links. The default auto-summarization in RIPv2 is preventing traffic
from routing properly throughout this topology.

Test 1. Description: Frame Relay Connectivity Test
Goals of Test:
The goal of the baseline is to verify that the Frame Relay network is up and running with the
proper protocols and features.
Data to Record:
Configurations
Interface status
Routing Tables
CPU & Memory
Ping Test Output
Estimated Time:
45 minutes total
30 minutes build
15 minutes test
Test 1. Procedures:
1. Build the topology according to the diagram shown in Figure 1 without Ethernet backup link.
Assign IP addresses according to the IP address plan. To configure the serial connections
through the Frame Relay network, you will need to change the encapsulation type to frame relay.
Then use the frame-relay map ip command to identify what circuit needs to be used to reach
the distant IP address. Lastly, turn on the interface. For example, on the Edge2 router, you need
to enter:
Edge2(config)#interface Serial 0/1/1
Edge2(config)#encapsulation frame-relay
Edge2(config-if)#frame-relay map ip 172.18.0.10 100 broadcast
Edge2(config-if)#no shutdown
Notice that you are using the BR3 Serial 0/1/0 address and connecting it to the local 100 DLCI.
The ‘broadcast’ will allow EIGRP multicast updates to use the link as well. The BR3 router Serial
0/1/0 will need to be configured in a like manner.
2. Create a basic configuration on each device. Include applicable passwords, device names,
default routes, default gateways, and activate interfaces.
4. Telnet to each device in the configuration and verify that each is reachable.

5. Start a log file and get the “show running-config”, “show ip route”, “show processes
cpu sorted”, “show interfaces” and the first few lines of “show memory” . Save the log file
for later analysis. Repeat for all devices in the topology.

8.2.5 Testing Design Redundancy
Objectives
• Using the test plan, configure the backup links and verify the failover works as expected.
In this exercise, you will configure a Frame Relay network and a backup link. Once the network is built and
configured, you can perform a Frame Relay Connectivity Test, Floating Static Routes Configuration Test and a
Link Failure Test specified in the designer’s test plan. Download and complete the Redundancy Test Plan
document in addition to the PT activity.
Required files: Testing Design Redundancy.pka and Redundancy Test Plan
Test 1 Frame Relay Connectivity Test
• Configure Edge2 and BR3 hostnames and LAN connection to Switch0. Use the address table in the
Redundancy Test Plan. To configure the serial connections through the Frame Relay network, you will need
to change the encapsulation type to frame relay. Then use the frame-relay map ip command to identify what
circuit needs to be used to reach the distant IP address. Lastly, turn on the interface. For example, on the
Edge2 router, you need to enter:
Edge2(config)#interface Serial 0/1/1
Edge2(config)#encapsulation frame-relay
Edge2(config-if)#frame-relay map ip 172.18.0.10 100 broadcast
Edge2(config-if)#no shutdown
Notice that you are using the BR3 Serial 0/1/0 address and connecting it to the local 100 DLCI. The
‘broadcast’ will allow EIGRP multicast updates to use the link as well. The BR3 router Serial 0/1/0 will need to
be configured in a like manner.
• Configure EIGRP (AS 1) on Edge2 and BR3. Advertise only the networks connected to the FrameCloud and
Switch0. On BR3, do not send advertisements out fa0/1.

CCNA Discovery
Test 2 Floating Static Routes Configuration Test
• On Edge2, configure fa0/1 using the addressing given in the Test Plan.
• On Edge2, configure floating static routes (AD=130) to 172.18.225.0/25 and 172.18.225.248/30 through
the back-up network using the local interface argument.
• On BR3, configure fa0/0 using the addressing given in the Test Plan.
• On BR3, configure a floating default route (AD=130) through fa0/0.
Test 3 Link Failure Test
• On Edge2, shutdown interface s0/1/1 and wait a few seconds.
• From Edge2, ping 172.18.225.1. Troubleshoot until it is successful.
• On Edge2, turn interface s0/1/1 back on and wait a few seconds.
• From Edge2, ping 172.18.225.1. Ensure the path is back through the Frame network.
