Abstract: MPLS technology is being widely adopted by service providers worldwide to implement VPNs to connect geographically separated customer sites i.e., Inter-provider VPN network. In this project we first briefly describe VPNs which are behind the scope of secure private MPLS connections such as several VPN deployments emerged from the sudden growth of requirements. We then discuss about the requirements of interconnections from customer end to service provider in one's perspective. We then propose and discuss the methods used for deployment options from service providers point of view. The usage of peer-to-peer model had overcome the drawbacks of the Overlay model and paved way for optimal data transport via the Service Provider backbone. Hence, the Service Providers would actively participate in customer Layer 3 routing. Customer Layer 3 routing information is carried between routers in the provider network and customer network. Layer 3 VPNs implemented on MPLS backbone of service providers are referred as “MPLS L3 VPNs” In this paper we present a novel method of communication among branches or partner branches of an organization each of them situated at distinct geographical areas with absence of the same ISP in every area. We came up with an idea of designing an Inter-provider network i.e., connecting multiple ISPs with the private network mechanism which provides global reach ability. It deals with the security issues confidently and provides the replacement of Internet in Private/Public organization
