Implementation of IPv6 Internet Service with MPLS Networks and MPLSL3VPN Service in IPv6 Networks

Exchanging the data packets seems as very challenging task due to exponential growth in network interface. Meanwhile, this increased interface makes use of next generation of internet protocol (IPv6) which will eventually replace the IPv4. Major issues in this replacement is the compatibility, both requires different set of routing protocols. Multi-Protocol Label Switching, a rapidly growing tele-communication infrastructure technology which works on special protocol suitable for both versions of Internet Protocol. MPLS uses the third OSI layer addressing coupled to second layer speed in switching and this paves the way for greater transfer of information, voice and video traffic. Virtual Private Network is the fastest growing technology for connecting the dispersed sites of same customer using the public network without any interference with other networks. This is an attractive technology to service providers because it enhances the flexibility for using variety of classes of services. This paper deals with the implementation of IPv6 networks for internet services using MPLS background which offers increased transfer in data, voice and video traffic. It also deals with, implementing MPLS based Virtual Private Network in IPv6 infrastructure using GNS3 simulator. This is done on behalf of the Border Gateway Protocol (BGP) which isolates the dispersed site in an Autonomous System (AS), connected to a public network.
