Design and Implementation of an Igp-Based Network for Enterprise Applications

: This project aims to implement and optimize Interior Gateway Protocols (IGP) within a network infrastructure. IGPs are crucial for routing within autonomous systems, providing efficient and reliable routing paths. The project focuses on the implementation of RIP v2 as the primary IGP, with comparative analysis against OSPF and EIGRP. The network is designed using Cisco Packet Tracer, implementing a three-tier hierarchical architecture comprising Core, Distribution, and Access layers with VLAN segmentation, HSRP gateway redundancy, Port-Channel aggregation, ACL-based security policies, and RIP routing across all Layer 3 interfaces. The implementation covers a complete enterprise scenario including department VLANs, server farm connectivity, remote location routing, and internet access through core routers. Comprehensive testing validates end-to-end connectivity, failover behaviour, and routing convergence. The outcomes provide actionable insights into best practices for deploying IGPs in enterprise-level networks and justify the strategic case for migrating from RIP to OSPF in production environments.
