Objective:
By completing this assignment, students will be demonstrating their knowledge and skills leant from week 1 to week 5 that include:
- IP address planning
- Local Area Network technologies
- Implement and configure Local Area Network of medium complexity in Cisco Packet Tracer
Scenario
Sydney Wonderers Limited is a manufacturing company who has recently restructured their business model. As part of their restructuring process they need to develop a new Local Area Network to meet their business requirements. You are hired by the company to design and build their computer network.
The first phase of the project involves designing and development of a network for a number of buildings of the company, as shown in the Figure 1 below.
Figure 1: Building Location
The location of different departments within the buildings and the location of main servers of the computer network are as follows.
- Buildings A and B hosts Manufacturing and Warehouse Departments
- Building C and H hosts Laboratory and Engineering Departments
- Building F hosts Stores department
- Building D hosts Human Resources Department
- Building K hosts main servers of all departments
The computers and the other equipment requirements are given in the table below;

The following are the requirements that need to be fulfilled in designing the network.
- Each department should be placed on a separate subnet for network management purposes.
- Departments located within the same building should use the same Layer-2 switches. VLANs must be used to separate the traffic between the departments.
- Layer-3 switches must be used for routing between VLANs within the internal network.
- The network should be designed with high performance and high availability requirements in mind, using Ether channel and First Hop Redundancy technologies.
- The company uses a single gateway router to access the ISP network. Network Address Translation should be used on the gateway router to hide internal IP addresses.
- 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 (X and Y are the last 2 digits of your student ID).
Specific Requirements:
To complete this assignment, you are required to take the following steps.
1. Design and draw the network topology using Packet Tracer software (or other drawing tools). Clearly label the buildings, departments, switches and the router in your topology diagram.
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 company and the ISP router has been assigned with network 220.2.X.0/24 (X is the first digit of your student ID).
Create the tables and provide the necessary details of the design for each subnet similar to below.

3. Label the drawn network topology with corresponding subnets and IP addresses and then take screenshots of the diagram.
4. Design appropriate configuration scripts for the router and for the switches to implement the proposed network. Where necessary, your configuration design should account for VLAN, Routing, NAT, and Redundancy.
Place configuration of each device into a table similar to the one below.
|
SWITCH1
|
|
(Type the script here as below, NOT using screenshot from Packet Tracer)
S1: enable
S1: configure terminal S1: . . .
|
Then, enter the scripts onto the designed network on Packet Tracer to implement a functional network.
5. Perform necessary verifications 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 the 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.
