ASSIGNMENT-1 (20%)
LOCAL AREA NETWORK TECHNOLOGIES
Objective:
By completing this assignment, students will be demonstrating their
knowledge and skills leant from week 1-5 that include:
o IP address planning
o Local Area Network technologies
o Implement and configure Local Area Network of medium complexity in
Cisco Packet Tracer
Scenario
Victoria University Company has recently restructruing and needs to develop a new
local area network to meet business requirements. You are hired by the company to
design and build the network.
The initial phase involves design and development of a network for a number of
uilding as shown in the below map.
The physical organization is as follows:
Building L hosts Sport and Health Departments
Building M hosts Sport and Health Departments
Building G hosts Business and Engineering Departments
Building A hosts Human Resources and Business Departments

NIT2222 –NETWORK TECHNOLOGIES
Building K hosts main servers of all departments.
The network requirement of each department is detailed as follow:
Sport
Number of employee 100
Each employee has 01 PC + 01 IP Phone
The department has 1 server
Health
Number of employee 50
Each employee has 01 PC + 01 IP Phone
The department has 1 server
Business
Number of employee 50
Each employee has 01 PC + 01 IP Phone
The department has 1 server
Engineering
Number of employee 30
Each employee has 01 PC + 01 IP Phone
The department has 1 server
Human Resources
Number of employee 10
Each employee has 01 PC + 01 IP Phone
The department has 2 servers
After discussing with the company leaders and their technical staff, both sides have
agreed with the following technical requirements:
Each department should be placed on a separate SUBNET for management.
Departments located within the same building should use the same Layer-2
switches. VLAN must be used to separate traffics between departments.
Layer-3 switches must be used for routing between VLANs of the internal
networks.
The network should be designed with high performance and high availability
equirements using Ether channel and First Hop Redundancy technologies.

The company uses a single gateway router to access an outside router of ISP.
Network Address Translation should be used on the gateway router to hide IP
address of internal network.
The network should be designed to optimize the cost i.e. you should try to use
least numbers of network devices and links.
The company was assigned the following IP address range to use for their
networks: 172.XY.0.0/16 (XY is the last 2 digits of your student ID)
Specific Assignment Requirement
To complete this assignment, you are recommended to take the steps below:
1. Design and draw network topology using packet tracers (or other drawing
tools). Clearly label the buildings, departments, switches and router.
(10 marks)
2. Identify how many subnets are required for your proposed topology. Design
the subnets based on the given network address (172.XY.0.0/16) to optimize
the address spaces (using the second approach – number of hosts needed).
Note: the link between the gateway router of the university and ISP router has
een assigned with network 200.1.X.0/24 (X is the first digits of your student
ID).
Create a table and provide details of the network design for each network such
as below:
Sport
Allocated subnet/Mask
Network address
Default gateway address
Valid host address range
Broadcast address
(20 marks)
3. Label the drawn network topology with co
esponding subnets and ip
addresses and then take screenshot
(5 marks)

4. Design appropriate configuration script for Routers and Switches to implement
the proposed network. Where necessary, our configuration design should
account for VLAN, Routing, NAT, and Redundancy.
Place configuration of each device into a table as below:
Then, enter the script into packet tracer to implement a functional network.
(50 marks)
5. Perform necessary verification to test the performance of the proposed
network. All computers should be able to ping to any other computers on
different networks and to the port on router. If either of the Layer 3 switches
fails, the network should still be functional.
Use necessary screenshots of ping and show commands on computers,
switches and routers to show the status and performance of your network.
(15 marks)
Submission
You have to submit a design document as outlined above with a working packet
tracer file to VU Collaborate Submission Box by the due date.
DO NOT ZIP THE SUBMISSION FILES
You may be asked to demonstrate your solution a long with the document to the
lecturer / lab tutor.
