This paper investigates the performance & configuration of Enhanced Interior Gateway Routing Protocol (EIGRP) using the Virtual Private Network (VPN). The VPN is used to implement peer-to-peer link connectivity between the customer locations. In this paper, the Hub and the Spoke topology are ensured to send traffic thus it ensures safe and encrypted connection. Performance optimizationis done by automatic routing decisions for data transmission between the sites and it enhances end to end connectivity. The proposed method of EIGRP uses Diffusing Update Algorithm where it takes only 90 milliseconds to achieve the convergence time. The proposed method ensures packet delay and does not have any boundary decisions between routers. The main advantage of the proposed method is the efficiency of EIGRP which is more advanced than Open Short Path First (OSPF). The GNS3 software shows that EIGRP provides better performance than OSPF protocol by their administrative distance, convergence time and metric calculations.
