This paper presents the performance of Virtual Private Network (VPN), Established through IGP- Interior gateway protocol and BGP- Border gateway protocol. The topology was simulated using GNS3 simulator. Which is a Graphical Network Simulator. Information is the true universal currency which we all carry with us every day. Thanks to how computer system connects us, we can share information globally, to share that information securely VPN connections are used widely. Which keeps your information secure and anonymous. Network testing such as ping command has been used to measure the connectivity as packet transfer. We have also analyzed a transmission of packet by using Wireshark tool. In this Paper we have established a VPN for a company whose head office is in Hyderabad and branch office is at Bangalore. A secure IPsec VPN tunnel has been created over a public network (Internet). This work is significant to forecast of network design and to analyse the performance of VPN.
