In modern enterprise and campus networks, maintaining seamless connectivity, scalability, and performance is a major challenge when multiple departments share the same network segment. Such configurations often lead to excessive broadcast traffic, reduced efficiency, and security vulnerabilities. Additionally, static routing becomes inefficient and prone to configuration errors during network changes. This project focuses on implementing Virtual Local Area Networks (VLANs) and OSPF-based Inter-VLAN Routing on Juniper SRX300 devices to achieve optimized network segmentation and dynamic routing. VLANs are configured to logically separate departmental traffic, thereby reducing broadcast domains and enhancing network security. Inter-VLAN routing enables communication between different VLANs, ensuring seamless connectivity across departments. The Open Shortest Path First (OSPF) protocol is used to provide scalable and adaptive routing, allowing the network to automatically adjust to topology changes. The iPerf tool is utilized to analyze network performance parameters such as throughput, latency, and bandwidth utilization, validating the effectiveness of the proposed setup. Experimental results demonstrate improved network performance, reduced broadcast traffic, and enhanced routing efficiency, ensuring a secure, reliable, and high-performance network infrastructure.
