Most of the Virtual Private Network (VPN) suffers from security related and overhead problems. During the inter domain routing, the conventional protocols require each gateway to resend its routing table periodically to all its neighbors thus increasing the delay. Since VPNs carry sensitive information over an insecure network, the traffic in this network has to be transmitted reliably and securely. In this paper, the authors propose a topology aware reliable routing protocol for inter-domain routing in VPN which securely transfers the data. By simulation results, they show that their proposed protocol is better than the traditional routing protocols of VPN.
