This paper proposes internet access along with MPLS VPN network to provide internet access connectivity for the customer along with their MPLS VPN connectivity. MPLS VPN network are service providers that provide MPLS Layer 3 VPN service connectivity for customers. Usually customer request internet access from the service provider that contains access. It is possible, that in case of MPLS VPN, service provider can provide internet access for customer as well. Internet access for VPN can be provided by a variety of ways with the MPLS architecture. Here internet access is provided to customer through internet service provider in ISP router. In current generation, it is very much necessary to access the Internet from an MPLS-based VPN along with addition to progressing to maintain the VPN connectivity among corporate sites. This model configuration focused on providing Internet access from the VPN Routing and Forwarding (VRF) that contains the default route to the Internet Gateway Router (IGW).

The proposed system uses three internet service providers, which provide connectivity to the customer. Three ISPs are used to provide MPLS VPN service to the customer and the fourth ISP router is used to provide internet access for the customer who also has MPLS VPN service. The below session describes how to design an MPLS CORE for internet access such that VPN remains secure. The implementation of internet over MPLS VPN is simulated by using a software GNS3 (Graphic Network Simulator) tool, which provides internet access by implementing internet in MPLS VPN technique on ISPs. The principle of this paper is to demonstrate the model configuration used to access the Internet from a Multiprotocol Label Switching (MPLS)-based VPN using a global routing technique.
