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.

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

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.

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
Designing and Supporting Computer Networks
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.
Background / Preparation
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.
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
have redundant links between switches. Why are all of the link lights green in this topology?

Designing and Supporting Computer Networks
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 reconverge. 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 the Simulation tab.
b. By default, Scenario 0 should be displayed in the Scenario window. Click 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 the Simulation tab.
c. Play Scenario 0 again by clicking 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 the dropdown arrow to the Scenario window and select Scenario 1.
b. Play Scenario 1 by clicking 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.
b.
c.
d.
Delete the trunk link between Star1 and Star2.
Since the star topology has no redundant links, the network will not need to re-converge.
Play Scenario 1 again and observe the flow of traffic from S2A to S4B.
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 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.
b.
c.
d.
e.
Delete the trunk link between FM2 and FM3.
Switch to the Realtime mode.
Allow time for the network to converge. (This may take several minutes.)
Play Scenario 2 again and observe the flow of traffic from FM1A to FM3B.
Click Clear Event List when the Buffer Full window appears and click the Reset Simulation button.
Reflection
1. How was the effect of the network failure in the star topology different from the partial mesh and full mesh
topologies?

CCNA Discovery
Designing and Supporting Computer Networks
Background / Preparation
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 of their employees, the HR server is only accessible by 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.
Step 1: Verify network connectivity
a. Verify that all of the PCs can communicate with each other and with the servers.
b. Verify that the Internet Host can access the Web server (192.168.0.3), Sales server (192.168.10.2) and
HR server (192.168.40.2) using the browser.
Step 2: Examine the Access Control Lists that are configured on the routers
a. Access the Distribution2 router. Use the following commands to view the ACL that has been configured
on the Distribution2 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:
• show running-config
• show access-lists 100
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.
f. Your completion percentage should be 100%. If not, click Check Results to see which required
components are not yet completed.
Step 4: Examine the effects of the ACLs
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.
Reflection
1. How can ACLs be used to control the flow of network traffic?

3.1.1 Investigating Existing Network Devices
Objective
•
Use router and switch commands to obtain information about an existing network.
Background / Preparation
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 commands 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.
Do 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.

3.4.3 Placing Wireless Access Points
Objective
•
Use available tools to perform a wireless site survey.
Background / Preparation
A wireless network consists of one or more wireless access points to provide coverage for wireless clients in
an office environment. The goal of the site survey is to find the optimal number and placement of access
points to provide coverage where it is needed and, for security reasons, to minimize coverage where it is not
needed. We will use the tools available in Packet Tracer to simulate a site survey of a one story office
building with two access points installed in the ceiling.
The Linksys WRT300N wireless access routers are used to simulate access points installed in the ceiling, a
PC with a Linksys WMP300N interface installed is used to simulate a laptop computer with wireless capability.
Required file: Placing Wireless Access Points.pka
Step 1: Conduct the wireless site survey.
a. In the logical view of the network observe which access point the Wireless PC is associated with.
b. Access the Wireless PC and choose the PC Wireless button on the Desktop tab. Click the Connect
tab in the Linksys window and observe the signal strength from both access points. Minimize the
Wireless PC window.
c.
Click the Physical Workspace tab in the upper left hand corner of the interface. Click the Home
City. The crosshatch ovals represent areas of wireless coverage. Note the areas outside of the
Corporate Office that have coverage.
d. Click the Corporate Office. Observe the areas of coverage inside the building and the placement of
the access points and the Wireless PC. In a real environment the wireless coverage areas would be
invisible. Mark the location of the access points on the Building Diagram below. Mark the location if
the Wireless PC and note the signal strength for each access point.

PC window and click the Refresh button. Note on the Building Diagram, at each location, the access
points (if any) and their signal strength. Minimize the Wireless PC window.
f.
Continue until the entire building is surveyed.
Step 2: Relocate the access points to their optimal location.
a. Move the access points to assure that all areas inside the building have wireless coverage and that
coverage outside of the building is minimized.
b. Verify your placement by spot checking key locations within the building using the techniques from
Step 1 and adjust the placement as needed.

expect the result of performing these tasks will be?
____________________________________________________________________________
____________________________________________________________________________
____________________________________________________________________________
b. Why do you think that network administrators use redundant links in their network?

____________________________________________________________________________
____________________________________________________________________________
c.
Why is Spanning Tree Protocol necessary where there are redundant links?
____________________________________________________________________________
____________________________________________________________________________
____________________________________________________________________________
Background / Preparation
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.
Step 1: Connect the Access Layer switches to the Distribution Layer switches.
a. Using the proper cables, connect the first interface on switch Access1 to the first interface on switch
Distribution1 and the second interface on switch Access1 to the first interface on switch
Distribution2.
b. Using the proper cables, connect the first interface on switch Access2 to the second interface on
switch Distribution1 and the second interface on switch Access2 to the second interface on switch
Distribution2.
c.
Using the proper cables, connect the first interface on switch Access3 to the third interface on switch
Distribution1 and the second interface on switch Access3 to the third interface on switch
Distribution2.
d. Using the proper cables, connect the first interface on switch Access4 to the fourth interface on
switch Distribution1 and the second interface on switch Access4 to the fourth interface on switch
Distribution2.
e. Your completion percentage should be 100%. If not, click Check Results to see which required
components are not yet completed.

Step 2: Observe the operation of Spanning Tree Protocol.
a. Wait a few minutes for Spanning Tree Protocol to open up forwarding ports that are indicated by the
green link lights. The ports whose link lights remain orange are blocked by Spanning Tree Protocol.
b. Observe which ports are blocked. Enter Simulation mode to verify that packets from any switch can
be sent to every other switch in the network. Be sure that all events are visible in the Event List, then
click Auto Capture / Play.
Step 3: Reflection
a. Why do you think Spanning Tree Protocol blocked the links that it did?

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.
Background / Preparation
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.
Step 1: Verify network connectivity
a. Start this activity in Realtime mode.
b. Observe the link lights on the connections. Before testing basic connectivity all links should be green.
c.
Verify that both PC devices can communicate with each other by using the command prompt on the
PCs to ping all end devices (PCs and servers).
d. Verify that each PC can view the web pages of both servers.
Step 2: Create the Access Control Lists that will be configured on the Edge1 router
NOTE: There are many possible ways to write an ACL and the true test is does it work or not. However, for the
purpose of this activity there is a specific way that the ACL must be written to show 100% Completion. Special
considerations:
• Use any instead of 0.0.0.0 255.255.255.255.
• Use the name of the port rather than the number (ex. – www instead of 80).
• Use 100 to identify the ACL.

inside address.
e. Permit an ICMP echo-reply to reach any inside destination from any source.
f.
Permit an ICMP unreachable message to reach any inside destination from any source.
g. Deny all other traffic.
Step 3: Examine the Access Control Lists that are configured on the routers
a. Click on the CLI tab on Edge1 to examine the ACLs that have been configured.
b. Use the following commands to view the ACLs that have been configured on the routers:
• show running-config
• show access-lists 100
Step 4: Determine the appropriate interface to apply the ACLs
a.
b.
c.
d.
e.
After examining the ACLs determine where the ACLs should be applied.
The ACL must be applied to an interface before it will affect the network traffic.
Remember that only one ACL per port, per protocol, per direction is allowed.
Using the CLI mode, apply the ACL to the appropriate interface on the Edge1 router.
Your completion percentage should be 100%. If not, click Check Results to see which required
components are not yet completed.
Step 5: Examine the effects of the ACL
a. Verify that the appropriate traffic is permitted or denied.
b. The Inside PC should be permitted to:
• Ping all devices (use the command prompt)
• Make HTTP request from the Web Server at 192.168.2.10 (use the Web browser on the Inside
PC)
• Telnet to the Internet router at 172.16.1.1 (use the command prompt) – password = cisco. Use
the command exit to return to PC prompt.
• Use FTP to reach other devices (use Simulation mode and a Complex PDU to simulate the FTP
traffic – for the Complex PDU set the Select Application: FTP, Destination IP Address:
192.168.1.10, Source Port: 50000, One Shot Time: 1)
c. The Outside PC should be denied the following:
• Ping to Edge1, Core, Inside PC, and Data Center (use the command prompt)
• Make HTTP request from the Data Center 10.0.10.20 (use the Web browser on the Inside PC).
However, it should still be able to reach the Web Server at 192.168.2.10.
• Use FTP to reach other devices (use Simulation mode and a Complex PDU to simulate the FTP
traffic – for the Complex PDU set the Select Application: FTP, Destination IP Address:
10.0.10.10, Source Port: 50000, One Shot Time: 1)
d. All other network traffic should be denied from reaching the 10.0.10.0 network.
Reflection
1. With the current ACL applied, would you be able to Telnet from the Outside PC to the Edge1 router at
172.16.1.2? Why?
_______________________________________________________________________________________
_______________________________________________________________________________________
2. Why is it always necessary to have at least one Permit statement in an ACL?

Disable auto-summarization in RIPv2.
Test and verify full connectivity
Background / Preparation
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.
This activity has multiple windows of instructions. Select the ">" button to view the next portion of instructions.
Task 1: Examine the network requirements.
The addressing for the network has the following requirements:
• The link between R1 and R2 is currently configured with the 209.165.202.244/30 network.
• The link between R1 and R3 is currently configured with the 209.165.202.248/30 network.
• The link between R1 and R4 is currently configured with the 209.165.202.252/30 network.
• The R2 LAN and its devices are already configured with the 192.168.40.32/27 network.
• The R3 LAN and its devices are already configured with the 192.168.40.64/27 network.
• The R4 LAN and its devices are already configured with the 192.168.40.96/27 network.
Task 2: Verify connectivity to next-hop device.
You should not have connectivity between end devices on different subnets yet. However, you can test
connectivity between two routers and between an end device and its default gateway.
Step 1. Verify WAN connectivity.
a. Verify that R2 can ping across the WAN link to R1.
b. Verify that R3 can ping across the WAN link to R1.
c. Verify that R4 can ping across the WAN link to R1.
Step 2. Verify that Host-A, Host-B, Host-C, Host-D, and Printer can ping their respective default
gateways. If the pings are unsuccessful, check device configurations.

For each test to be performed state the goals of the test, the data to record during the test, and the
estimated time to perform the test. Test 1 is given as an example.
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:
Itemize the procedures to follow to perform the test.
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.
3. Console into one of the devices in the topology and ping all of the other devices in the topology.
Record any anomalies.
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.
Test 1. Expected Results and Success Criteria:
List all of the expected results. Specific criteria that must be met for the test to be considered a
success should be listed.
1. All networking devices, except ISPX, are connected and accessible through Telnet.
2. Hosts can ping successfully to other hosts, except ISPX on the network.
Test 1. Results and Conclusions
Record the results of the tests and the conclusions that can be drawn from the results.
Test 2. Description: Floating Static Routes Configuration Test
Goals of Test:
Data to Record:

8.2.5 Testing Design Redundancy
Objectives
•
Using the test plan, configure the backup links and verify the failover works as expected.
Background / Preparation
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 Stadium Redundancy Test
Plan document in addition to the PT activity.
Required files: Stadium Redundancy Test Plan
Test 1 Frame Relay Connectivity Test
•
Configure Edge2 and BR3 hostnames and the LAN connection to Switch0. Use the address table in the
Stadium 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 which circuit needs to be used to reach the distant IP address. Lastly, enable 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.
