Figure 1 : Physical Topology
Logical network topology: refers to the manner in which data moves via a network between devices (computers, phones, etc.); it is independent of the physical connection. The data channel in the circuit travels logistically.
Figure 2 :Logical Topology
- What is the difference between a logical connection and a physical connection?
A logical network arrangement is the communication strategy that connects two networked
computers. A logical arrangement is the flow of data between two systems. In reality, the
network connection is defined by the network's logical design. The physical arrangement is
configured using logical scheduling. Logical networking may be improved and utilized to link two
or more machines. The virtual network design is logical, while the physical network design
specifies the operation of the network hardware. Physical designs govern the flow of data or
communication between two networks, whereas logical designs control the flow of data or
communication between two computers connected by a cable.
2. Discuss and explain the user requirements for general network design.
User needs (as stated in the report):
As we can see, I have designed the requirements with three floors: the ground floor, first floor,
and second floor.
For specifically, I will introduce each floor below:
Ground Floor: There will be 33 people on the first floor, including 15 salesmans, 12 employees, 5
managers and IT, so I decided to use 2 switches with 24 ports, 1 room for salesmans and
managers, and 1 room for it and the employees. I installed a router in case some guests come
over and use their equipment. Also, I set up 3 printers so that salesmans, employee and
managers can easily use them, and they are on the same VLAN as the PCs. The bottom VLAN It
can ping the It room on the first floor.
First floor: On the first floor, I designed an IT laboratory, a laboratory where customers learn
about computers, and a waiting room that already has routers for guests. I have 20 PCs set up for
customers in a customer lab. So I chose the underlying 24-port switch. From ports 2 to 22, I
created a VLAN customer to help the customer's lab ping the other labs on the second floor. The
remaining 2 ports I created VLANs for it and the router.
Second floor: Customer PC room, equipped with 31 PCs and routers, convenient for customers
and IT to study and connect easily. The customer VLAN helps the student labs and IT employees
ping each other as well as the labs on the first floor.
On the first level, I installed a router to link the network and a multiplayer switch. This switch is
more powerful and efficient than others, and it can link three LAN networks.

Because I have a configuration sub-interface in the Router so the different VLAN in the network
still can ping each other. So the expected results are successful.
**2. Evaluate network design
The network speed is rapid since all devices may connect to each other as soon as possible,
ensuring that the connection is not isolated. Furthermore, the finish may now be easily applied or
deleted. It is an excellent model since it is basic and has few flaws. If one device fails, the entire
network is not affected.
- Drawback:
No firewall. Because there is no integrated wireless network, mobile phones and laptops cannot
connect. The prices of the gadgets have not been cut to the bare minimum.
Then, by turning on DHCP in each device, the linked devices automatically configure the IP
address, default gateway, Subnet mark, and so forth.
As may be seen, go to Manager PCs --> Desktop --> IP Configuration —> Enable DHCP. The default
gateway, DNS server, and IP address all begin with 192.168.10.....
Finally, I repeated the process with the other computer devices, printers, and DHCP 2.
E. Task 3 - Implement a networked system based on a
prepared design (P7)
1. Network Implementation
Cisco Packet Tracer was used to implement the topology. Before we can finish the setup, we must
first accomplish the following:
- Fundamental router setup (hostnames, password, IPs)
- Configure DHCP
- Create a Static Route with a Next-Hop Address and an Exit Interface.
Consider the following network implementation:
Example the network implementation:
