MPLS VPN using IPv4 and IPv6 protocol Service implementation is done for providing different services to the customer. Layer3 virtual private network implementation using IPv4 and IPv6 routing protocol is done and with this policy is implemented using MP-BGP as exterior gateway protocol. Layer 3 virtual private network in internetprotocol version 6 is known as 6VPE technology, which is implemented using BGP and layer 3 VPN (VPRN for alcatel) is implemented within a network shown. Service flow through this network through different user demonstrating VPN service for specific user is also shown in this paper.
