Neighbour Discovery for IPv6 forms the cornerstone of efficient network communication in the IPv6 realm. It facilitates address resolution, duplicate address detection, and router discovery, making it indispensable for seamless communication across IPv6 networks. However, as enterprises migrate to IPv6, the conventional ND6  protocol may face challenges in terms of scalability and performance.

To address these limitations, our research focuses on incorporating the enhancements proposed for 6lowpan in RFC 6775 and 8505 into the mainstream ND6 protocol. These RFCs present innovative solutions that improve the speed and accuracy of neighbour discovery while optimizing the use of multicast messages.

In particular, RFC 6775 outlines mechanisms for optimizing ND6 for low-power and lossy networks (6Lowpan). By bringing these optimizations into the mainstream ND6, we aim to enhance its performance and adaptability, especially in enterprise settings.

Additionally, RFC 8505 proposes solutions to reduce unnecessary traffic and processing overhead in ND6, further optimizing its performance in larger networks. This reduction in overhead is critical for scaling ND6 to meet the demands of modern enterprise environments.

In this presentation, NITK students Sudesh, Advaith, and Kavya will elaborate on our hypothesis, the advanced packet modifications, and their efforts in implementing these upgrades in FreeRtr – an open-source IPv6 routing software. They have been actively involved in the implementation of these enhancement.
