Project scope
In this project modern network for VIC Warehouse pty Ltd. which consists both wired and wireless IT
infrastructure to connect to its branches located at Footscray, Ballarat, and Bundoora. The headquarter
is located at Melbourne CBD.the host requirements for the network is given in the table below
Locations Buildings Number of Hosts
Footscray 1 6
2 14
3 22
4 28
Ballarat - 40
Bundoora - 20
The Footscray warehouse consists of four buildings with different hosts requirements , building 1 has 6
hosts , building 2 has 14 hosts, building 3 has 22 hosts , and building 4 has 28 hosts also the building 4
has marketing and finance department and the hosts are shared by both of these departments .
There is requirement of wireless access using WIFI routers at each branches. There should not be any
restriction for the employees to use the network they must be within the company, they should have
privilege to access the network from anywhere an at any time. Also the reliability of the network with
the time delay is very crucial parameter that must be followed strictly by the network engineer as the
customers can order products online, so there must be central server which is located in Melbourne and
it should be secured from any unauthorized access.
Project requirements (Hardware & Software)
 Routers: IP address 172.16.100.0/22 is the internal address of the LAN network which is to be
connected to the internet and other branch network, to do so we will need routers that will use
various routing protocol to route the data from one network to other. Recommendations are
shown in Appendix A. [1]
 Layer 3 Switch: it is similar to routers when we are routing data from local area network to other
networks. It is also helpful in DHCP protocol to allocate the IP address to the network.
 Switch: switch is a multiport networking device connecting all the local hosts like PCs in a star
topology, it works in OSI model layer 2 with MAC address
 PCs: the end point user interaction devices havingRJ45 connectors inbuilt and network interface
cards. [5]
 Wireless devices: the laptops and tablets are to be connected with WLAN devices working in
IEEE802.11 WIFI protocols. [7]

Network Topology Diagram
The network topology diagram is the connectivity diagram of each networking devices with each other
in the local area network. The diagram shown below is the demonstration of the network infrastructure
which is proposed for the company as per there requirements. The branches located at Footscray ,
Ballarat,and Bundoora are connected via routers and ISP , that is provided by the internet service
providers as the data is going out of LAN to internet . The routers are connected with the switches and
then the switches connects the end hosts. All the IP address or logical address are used within the LAN
are license free network address and thus whenever the data flows out or is received by the LAN from
ISP routers NAT (Network Address translation ) protocol is invoked to know exact location of source and
destination. The topology proposed here is star topology as it is most reliable and secure infrastructure,
whenever there is fault between any end devices the other network is not disturbed. [1]
The result of the structure configuration is a lot of outlines that give a physical format to the majority of
this data and demonstrate the connections among segments of the structure . One huge contrast
between a structure plan and a system configuration is that there is frequently an imaginative part to a
structure plan, while there is once in a while one for a system structure. There can be an imaginative
part to a system, for example, when it is a piece of a display, show, or meeting; be that as it may, most
by far of systems isn't seen by its clients.[2]
IP address for the organization
3 | P a g e

The logical address of all the layer 3 device in OSI model is crucial in any network design architecture,
the IP address can be classful or classless, here we are using classless IP address as subnetting used in
this case does not require any specific mask, and it can be variable. The 172.16.100.0 network address
used here is a public

Detailed Network Design in Packet Tracer
4 | P a g e

Switch configuration is Cisco packet tracer
VLAN configuration in switch
The VLAN is the backbone of modern computer network architecture as the large local area network is
very difficult to manage, it is bifurcated using VLAN. The network is said to be consisting of single
network when a large organization is using same set of network ID and managing the network centrally,
this reduces the cost and work of the network engineering also controlling and securing the network
becomes easier. The NAT or network address translation is other protocol which is very handy to
manage the network when using private IP address inside LAN. The VLAN ID is used in the switch where
the computers connected to the particular switch virtually knows it iis in different network so, it can’t be
accessed by other devices connected to the network, it can be accessed if same VLAN ID is used in other
switch also.
5 | P a g e

VLAN interface addition
Each interface of switch needs to add a separate of same VLAN ID according to the requirement of user,
if the user wants the ports to be accessed by all the devices, it should use VLAN trunk or default VLAN ID
for the switches.

VLAN IP addition
7 | P a g e

The virtual local area network VLAN300 is used here to add IP address 172.16.100.193 , it has the subnet
mask of 255.255.255.192.

Switch 3 as it can be configured to use DHCP , the below configuration in switch 3 is used for DHCP
address allocation to the devices.[8]

DHCP in WLAN devices
The wireless devices are all set to default DHCP mode, where it fetches the IP address being distributed
by WIFI routers. The figure shown below gives the detailed configuration of wireless device IP allocation
using DHCP.
17 | P a g e

IP address in needed in wireless devices also to connect with the WLAN routers, this is done by DHCP
protocol when mobile devices connects to routers. [5]
18 | P a g e

We can check the configuration being used in layer 3 using command show run. [5]
19 | P a g e

Testing the Network
The PING command is used to test the network, as it is the forwarding and acknowledgment check tcp
protocol which gives the time delay in network connectivity and also its reliability. The below figures
shows the ping command is successful, thus the network connectivity is successful. [1]
