Conclusion
In conclusion, the areas, subnets, and VLANs have been successfully configured, and the routers have been named according to a specific convention [1, 2, 3]. The passwords for privileged access mode and other requirements have been set and met other security requirements. Network and VLAN labeling have been meticulously implemented using the assigned network IDs. IP addresses have been strategically assigned and clearly labeled for both PCs and router interfaces. Additionally, servers have been labeled according to their respective services to ensure easy identification.
The implementation of OSPF for internal routing, as initially proposed, has been successfully realized. This configuration enables seamless connectivity between internal networks. Furthermore, traffic forwarding to the upstream service provider has been optimized, and efficient routing of network packets from the ISP has been established without the need for dynamic routing. This is achieved with minimal route entries to ensure optimal efficiency.
The sample network at Pulchowk campus has been effectively realized. This setup not only supports robust connectivity but is also designed to be scalable, accommodating future expansions and technological upgrades.
