Abstract

Today organizations are spread across the globe due to higher business activities. The network connectivity among the offices at different geographic locations has become a challenge for network professionals. VPN is used to counter this narrative. It has become a popular industry solution in recent years. MPLS is a relatively newer WAN technology providing advantages over other technologies. At the same time, it is compatible with existing technologies like ATM, FR, Ethernet and SONET. VPN having connectivity via MPLS infrastructure is known as MPLS VPN. It offers many advantages over traditional VPN solutions. In this project, MPLS based VPN is implemented in a corporate environment. Three regional offices of an organization are connected with the central site through MPLS based ISP’s network. Hub and spoke topology is implemented in this scenario. The connectivity among the sites is established and forwarding decisions are made on the bases of MPLS labels instead of IP addresses. Furthermore, it is also observable in results that MPLS doesn’t need any other tunneling protocol unlike traditional VPNs. It makes tunnels based on labels. Concerning the security requirements, it hides the customer’s network from ISP’s network, which is discussed in the results section.
