Multi-Protocol Label Switching (MPLS) which was introduced by Internet Engineering Task Force (IETF) is usually used in communication networks which started attracting all the internet service provider(ISP) networks with its brilliant and excellent features that provide quality of services (QOS)and guarantees to traffic which carries data from one network to another network directly through labels. Virtual Private Network (VPN) is one of the highly useful MPLS applications which allow a service provider or a large enterprise network to offer network Layer VPN services that guarantee and carries traffic securely and privately from customer’s one to another through the service provider’s network. To support multiple customers that Customers Request for secure, reliable, private and ultrafast connections over the internet MPLS VPN standards include the concept of a virtual router. This feature called a VRF table. VRF or Virtual routing and Forwarding technology that permit a router to have various routing table or multiple VPN at the same time that they are located in the same router but they are independent and Also the VRF feature in VPN now allows different customers to use same IP addresses connected to the same ISP. A VRF exists inside a single MPLS router and typically routers need at least one VRF for each customer attached to that particular router.
