Introduction

This report demonstrates the application of networking concepts by completing three tasks: developing IP schemes, constructing the network simulation, and solving faults in a given pre-configured network. Task 1 specifically involves designing IPv4 and IPv6 addresses and deployment of the addresses on a network map. The second task involves setting up and testing the network in Cisco Packet Tracer including but not limited to the routing, VLAN, and DHCP - task three requires the student to identify and correct ten deficiencies proposed in a network simulation. The focus of the report is on real working implementation and structured problem-solving to guarantee a fully functioning optimal network.

Task 1: IP Schemes

Task 1 entails creating and implementing IPv4 and IPv6 addresses on a network plan. The IPv4 scheme comes with VLSM to make sure that addressing these subnets is done efficiently. The IPv6 scheme includes hierarchical addressing with global unicast and link-local addresses meeting the standard and best practices. Subnet distribution and sample host address to each IP scheme are drawn on a network diagram as shown below: Each of the schemes is planned according to the existing network requirements and future expansion.

Task 2: Network Simulation

Task 2 involves connecting a network and powering it using a Cisco Packet Tracer. The IPv4 addressing scheme is followed in the simulation while crucial aspects in the network are routing protocols, VLANs plus DHCP services. In the dynamic routing approach, the Open Shortest Path First (OSPFv2) protocol is used to implement routing in all the different areas of the network. To provide support for communication and interface with OSPF, static and default routing is usually configured at network boundaries (Chen et al. 2022).

This configuration aims at the logical grouping of network resources. Installs security to the network and improves performance. Another feature supported on layer 3 switches is the ability to perform inter-VLAN routing to allow traffic flow between VLANs. DHCP services are usually set up to make the end device deployment process easier through a programmed IP distribution.

Other forms of testing are checking device connectivity in and across subnets by using simple utilities such as ping and or traceroute utilities. Some of the key configurations that are confirmed by commands such as show ip route and show vlan brief are checked.

The simulation further affirms the achievement of exchanges within all the network areas and with the ISP (Dong et al. 2022). Test images along with the setup and result screenshots are displayed here. The Packet Tracer that has been designed is also part of the submission as it contains the fully completed simulation of the created network.

Task 3: Network Troubleshooting

Network Troubleshooting explores the systematic approach to diagnosing and resolving network faults, covering fault analysis, resolution, and final testing using tools like ping, traceroute, and show commands. It highlights identifying issues such as VLAN misconfigurations, DHCP errors, and routing mismatches to restore full connectivity and performance. For students seeking expert guidance in writing or understanding similar technical reports, an Assignment Helper from Rapid Assignment Help UK can provide step-by-step support to ensure clarity, precision, and professional presentation.

3.1 Fault Analysis

Fault analysis is concerned with recognizing the root causes that deny the network proper functionality. To better analyze the provided network simulation, it was studied for misconfiguration and connectivity problems as well as the protocol mismatch. Some of the common symptoms noted were devices on different subnets could not recognize each other, some routing paths were missing and VLAN configurations were out of sync (Garoosi and Hooman, 2022).

Tools including ping, traceroute and show IP route used in finding paths of packets and identifying breaks. Shutdown states or incorrect IP addresses were identified with the show IP interface brief. With showing neighbor and show IP protocols commands, missing network statements, or wrong area assignments in OSPF configuration were detected.

VLAN problem-solving included checking original trunks and VLAN assignments on a show VLAN brief and a show interfaces trunk (Hayakawa et al. 2021). DHCP misconfigurations were found using the command show running- configuration and verifying the range and scope of an IP address on clients. In the study, the researchers identified a total of ten faults at different modern network layers.

3.2 Fault Resolution

The framework required the following ten faults to be solved systematically: Misconfigured interfaces were corrected through no shutdowns and proper IP configurations were attained. There were improper VLAN settings and corrections were made by setting appropriate VLAN and trunk options on the switch. Some commands included switch port mode trunk and switch port access vlan where applicable. DHCP problems were solved where some of the DHCP pools were configured with the wrong subnet scopes and DHCP service was turned off in the routers.

Connectivity was then rerun after every correction using ping and traceroute among other tools. Static & default routes were evaluated to calibrate the correct communication with the ISP. The simulation was checked for gradual improvement to establish that all the faults had been corrected to 100 percent achievement (Li et al. 2021).

3.3 Final Testing

The final tests involved checking the functional finality of the network, as well as its performance and connectivity features. Connectivity for each device was also tested through the ping command and all the connected devices were communicating within and across subnets as follows. Static and default routing configuration was also proved by end-to-end testing of the ISP.

OSPFv2 dynamic routing was evaluated based on the ability to propagate routes and convergence using the command show ip route and show ip neighbor. VLAN communication was tested by passing data through devices in two different VLANs, thus verifying inter-VLAN routing configurations and trunking.

The status of the DHCP server was tested by resetting computer clients, to verify that the IP address had been successfully assigned (Wang et al. 2023). To check the settings of trunks and VLAN Proper segmentation and communication were checked using the two commands that show vlan brief and show interfaces trunk.

Testing showed a fault-free network with the right routing, VLAN operations, and stable DHCP services hence the Packet Tracer simulation result showed 100% functionality.

Conclusion

This report proved that it was possible to design, configure, and troubleshoot a network with IPv4 and IPv6 addressing and employ OSPFv2 in dynamic routing. Connectivity and configuration problems were worked through the network simulation in Packet Tracer, which was specifically constructed and verified. Fault analysis and rectification together with considering all faults found during the analysis were done systematically. The devices’ final testing showed efficient network communication and proper operation of the routing protocols. The structure of the network as well as specifies that detailed configuration, proper troubleshooting, and ample testing are crucial to achieving a working network.
