long as you explain your assumption and justify it.
PART I – Case Study by Dr. Vinod Mirchandani
1. Background
A NSW Oysters export company BayOyst Inc. has hired you as a Network professional
to setup a fully functional network in Sydney. The company has headquarters (HQ) in
North Sydney with branches in East Sydney and West Sydney.
The two branches of BayOyst and headquarters each have one Cisco 1841 Router.
The Routers at each of the branches are connected to the Head Quarters Routers by
a WAN and necessary protocols. Further, each branch of BayOyst Inc has three LANs
while the HQ of BayOyst has two LANs. Each of the three LANs in each branch of
MN602 Wide Area Networks Page 2 of 6
BayOyst needs to support 20 PCs. The HQ of BayOyst needs to support 30 PCs. The
router interfaces between the HQ and each of the branch Routers also needs to be
provided with suitable IP addresses. BayOyst has given you the network address
192.168.Your Group number.X/24 for the purpose of creating the addressing and to
subnet in the above described network of BayOyst Inc.
You need to carry out the following tasks and Justify your approach:
• Specify the number of subnets in the network topology and number of IP
addresses per subnet.
• Choose a WAN technology and protocols between the HQ and each of the
branch offices in the above case study with proper justification.
• Create and draw the topology as per the description given in the above case
study
• Specify the subnet masks for the subnetworks and usable host IP addresses in
each subnet. Show the subnets addresses in the topology that you have drawn
• Each of Router interfaces should be assigned the first valid host address of
the respective subnet.
• Each of the 20 PCs in each part of the network (as given in the above
description) should be assigned the last 20 valid host IP address of the
respective subnet.
• After completing the above tasks confirm that the network is fully functional that
is all devices in it can ping each other.
• Troubleshoot the network for any flaws in the design on Packet tracer.
• Based on the class size and time availability you may be asked to demonstrate
the entire network or a part of it on Physical Routers during Lab 11
demonstration along with Viva voce (Oral test.)
Practical Demonstration of Part 1 on Physical devices (10 marks)

This mark will be allocated individually. Depending on the number of students and
available devices the Tutor/Lecturer will decide if you have to demonstrate full network
or a part of it

PART 2 – Analysis of VLAN Network in Figure 1 from Configuration and
troubleshooting point of view. Depending on the number of students and
equipment numbers your Lecturer/tutor will decide if the demonstration will be
done by each student in the group or group based.
Case Study by Dr Vinod Mirchandani
A Computer company has hired you to create the Network topology shown in Figure
1 and ensure that it is fully functional i.e. each device in the network can be pinged.
The company also wants you to prepare a document for Troubleshooting of this VLAN
based network.
Your tasks are:
• Assign proper IP addresses to the different devices.
• Use proper cabling and protocols.
• Identify the different reasons due to which the network may not be fully
functional i.e. some of the devices or VLANs may not be accessible i.e. not ping
each other. Once you have identified these reasons create a flow chart to
explain the methods by which you can overcome these reasons. Justify your
methods.
• Familiarise yourself with the VLAN network of Figure 1 as you will be asked to
create it or a part of it with Physical devices. Your tutor will then ask your group
to move far away from your physical network in the lab and he/she will create
deliberate fault(s) in the physical network. You then need to refer to your
flowchart for Troubleshooting and identify the faults included by the
Tutor/Lecturer.
