Listener Subscription for IPv6 Neighbor Discovery Multicast and Anycast Addresses
RFC 9685, “Listener Subscription for IPv6 Neighbor Discovery Multicast and Anycast Addresses”, is a Proposed Standard document published in November 2024 by P. Thubert. It updates RFC 4861, RFC 6550, RFC 6553, RFC 8505, RFC 9010. The canonical text is published by the RFC Editor.
Abstract
This document updates the 6LoWPAN extensions to IPv6 Neighbor Discovery (specified in RFCs 4861 and 8505) to enable a listener to subscribe to an IPv6 anycast or multicast address. This document also updates the Routing Protocol for Low-Power and Lossy Networks (RPL) (specified in RFCs 6550 and 6553) to add a new Non-Storing multicast mode and new support for anycast addresses in Storing and Non-Storing modes. This document extends RFC 9010 to enable a 6LoWPAN Router (6LR) to inject the anycast and multicast addresses in RPL.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
