ICT102 Networking Report 3 Sample

Assessment Objective

The objective of this assessment is to evaluate student’s ability to design and configure a network using a network simulator for a given scenario and configuring routers, switches, firewalls, and other network components based on specific requirements.

ASSESSMENT DESCRIPTION:

This assignment is group-based. Each group will have 3-4 students. You can continue with the same group as for the previous assessment. In this assignment you will be designing and configuring a network for a university that has a Class B IP address of 148.23.0.0/16. There are two faculties and each faculty requires two separate subnets: one for staff and another for students. The faculty names and the number of hosts in each subnet are given below:

• Faculty of Arts: 400 students and 200 staff members

• Faculty of IT: 600 students and 300 staff members

Part 0

Declare team members contributions in the table below:

Part 1

Divide the allocated address space between department subnets as per requirements. Summarize the IP subnets and masks in a table like this:

Part 2

Construct the following network topology in GNS3 or Packet Tracer simulator. Ensure that all the hostnames and network addresses are well labelled.

Part 3

Configure the router using the assigned hostnames and IP address.

Part 4

Setup Virtual PC (VPC) in each of the four subnets as shown above. The virtual PC’s provide lightweight PC environment to execute tools such as ping, and trace route. For each faculty create two VPCs for students and two VPCs for staff. Each VPC should be able to ping the other VPC in the same subnet.

Part 5

Configure the access control list (ACL) on Router01 such that any traffic from Students’ subnets are blocked from entering the staff subnet. Traffic to and from other subnets should pass through. Pinging staff VPCs (in both faculties) from students’ VPCs should fail. In other words, student in each faculty should not be able to ping any staff computer in any faculty. Students can only ping students VPCs in any faculty. Staff members can ping any VPC (staff and students in any faculty).

Part 6

Configure DHCP services on Router01 such that all VPCs can get IP addresses dynamically assigned.

Part 7

Use the following checklist to ensure you network is configured correctly.

For each of your routers make sure to save your running configuration using the command write mem For the VPCs use the save filename command to save the configurations to a file.

Finally save the GNS3 (or Packet Tracer) project, i.e., the topology together with the startup configs. Zip the GNS3 (or Packet Tracer) project folder and submit it on Moodle with your report. Make sure your submission is complete and has all the necessary files to run the simulation.

Solution

Introduction

Dynamic host configuration protocol is the client-server protocol providing an internet protocol host with an IP address and other configuration information. DHCP protocol is applied in an open networking system to transfer information from one PC to another by using the stated IP address. For Assignment Help, This protocol applies to openly communicating with nodes but there needs permission from the local host. Using DGCP protocol, this is applicable to configure automatically configure all networking components by suppressing errors that occur in the network. This report will implement the application of the DHCP protocol in the university networking system The goal of the report is to implement the DHCP protocol to communicate between two departments Arts and IT.

Network configuration and Ping status

The network of the university is a three-layer network consisting of routers, switches, and virtual PCs. There is the configuration of routers as the host of the networks situated in the first layer of the network. The second layer consists of four different switches. The third layer consists of eight different PCs for connecting the people. There are the consists of the different IP addresses of the different devices. The condition of the networking is that IT students can not communicate with the staff of any of the departments. Overall network configurations are looking the same.

This is a three-layer network configuration containing the IP address of each of the component. The router provides internet connectivity to all of the respective nodes. Router C3725 has been placed in the system due to the availability of 10 different ethernet ports. The characteristics of this router are stated below.

The router contains a MiB size of 128 and NVRAM contains 256 KiB. This also contains the size of the I/O memory is 5 % of the RAM. Input and output memory is liable for storing all of the IP addresses inside the router. The next layer contains four switches that provide the connectivity of the 8 different computers. There is the connectivity of the 8 computers to the four different departments. IT students, IT staff, Arts students and Arts staff are using two different computers each. The DNS of each of the systems is the same which is 255.255.255.0. There are four different branches containing four different subnet masks148.23.0.1, 148.23.2.1, 148.23.4.1, and148.23.8.1. There is the connectivity of eight different computers that contain IP addresses of the same domains. IT students are using the IP addresses of 0,1,2,3 domains respectively. The ping status is getting successful in the internal communication. Interestingly, the ping status has been damaged while communicating with the staff of IT. The overall ping status is looking like the same.

Conclusion

This report concludes that the DHCP network protocol is widely accepted in automatic configurations. Applying the DHCP protocol the entire network traffic can be prohibited in a particular domain. The report has seen that using PC 1 one can send all the required information in nodes excluding IT staff.
