This study presents an enhanced Virtual Router Redundancy Protocol (VRRP) framework designed to improve network reliability, performance, and security in enterprise environments. As organizations increasingly depend on uninterrupted internet connectivity for critical operations, conventional redundancy mechanisms often struggle with latency, failover delays, packet loss, and security vulnerabilities. These limitations can lead to service interruptions and reduced Quality of Service (QoS), particularly in large-scale campus and enterprise networks. To address these challenges, the proposed framework integrates VRRP with First Hop Redundancy Protocols (FHRP), Hot Standby Router Protocol (HSRP), and dynamic access control mechanisms to provide a more secure and fault-tolerant network architecture. The proposed model was implemented and tested using Cisco Packet Tracer within a simulated campus network environment consisting of dual Internet Service Provider (ISP) links. The implementation focused on ensuring seamless failover, efficient load balancing, and secure routing operations during network disruptions. Performance evaluation was conducted using key metrics such as failover time, packet loss, and QoS performance. Experimental results revealed an average failover time of 11 seconds with zero packet loss during transition between active and standby routers, demonstrating significant improvements in network stability and service continuity. Furthermore, the integration of security-aware dynamic access control mechanisms reduced the risk of unauthorized routing participation and strengthened overall network protection. The findings indicate that the enhanced VRRP framework effectively eliminates single points of failure while supporting adaptive load balancing and secure redundancy management. The study therefore contributes to the development of scalable and resilient enterprise network infrastructures capable of maintaining high availability under varying operational conditions. In addition, the proposed framework provides practical insights for network engineers, system administrators, and researchers seeking reliable solutions for improving redundancy, security, and performance in modern enterprise and campus network environments.
