IPv6 Era Routing Protocol Evolution: Challenges and Innovations

Abstract

The shift from IPv4 to IPv6 has been accelerated by the Internet's explosive growth brought on by the development of linked objects. Reacting to the depletion of IPv4 addresses and to manage the growing number of networked devices, IPv6 was published with enhanced addressing capabilities and design improvements. But the significant challenges in IPv6 implementation have required current routing systems to adapt with IPv6 capabilities. This paper analyzes recent advancements designed to enhance the security, scalability, and efficiency of the protocols as well as the primary challenges to change routing protocols for IPv6. We examine protocols like OSPFv3, EIGRP for IPv6, and BGP-4+ and propose methods to improve protocol approaches to meet problems including growing address space, security, mobility, and routing table management. Furthermore suggested are prospective routes of development for routing technology in an IPv6-dominated Internet environment.
