Internet Protocol version 6 on virtual private Network provider edge routers

Abstract

The Internet protocols that is predominantly deployed and extensively used throughout the world. IPv6 is an IP protocol designed to replace IPv4. IPv6 quadruples the number of network address bits from 32 bits (in IPv4) to 128 bits. This provides more than enough globally unique IP addresses for every network device on the planet. This research concerns with the design of IPv6 VPN Provider Edge (6VPE) over Multi Protocol Label Switching Network (MPLS) without changing network backbone. This is because existing MPLS IPv4 infrastructure needs to be migrated to MPLS IPv6 infrastructure which is very expensive. It was applied using Graphical Network Simulator (GNS3). The performance parameters like success rate and the minimum, average and maximum round – trip time, latency have been evaluated and analyzed compared with IPv4. The results obtained reveal the applicability, performance as well as usefulness in employing 6VPE in MPLS.
