Multiprotocol label switching (MPLS)-VPN is widely deployed between enterprises and service providers to offer a variety of advanced services to maintain their security over a single infrastructure. Many service providers are replacing frame relay and ATM services with MPLS VPNv4. In order to deal with shortcomings of IPv4, IPv6 is a tremendous approach to build up a broader global Internet. As MPLS does not support IPv6, thus by taking benefit from the MPLS features, we transport IPv6 VPN traffic on MPLS IPv4 core network to refer it as MPLS VPNv6 in this paper. It is a prominent solution for enterprises as it has enhanced security with optimized network performance. It deals with issues of scalability, easy management, redistribution policies, overlapping, and shortcoming of IP addresses. In this paper, we have created a single network infrastructure of MPLS VPN over which IPv4 and IPv6 traffic can be routed without applying any additional stress on the network. MPLS VPNv6 enables multiple service providers to connect corporate clients and offices at a distinct location into one network.
