IPv6 Neighbor Discovery Multicast and Anycast Address Listener Subscription

IPv6 Neighbor Discovery Multicast and Anycast Address Listener Subscription This document updates the 6LoWPAN extensions to IPv6 Neighbor Discovery (RFC 4861, RFC 8505) to enable a listener to subscribe to an IPv6 anycast or multicast address; the document updates RPL (RFC 6550, RFC 6553) to add a new Non-Storing Multicast Mode and a new support for anycast addresses in Storing and Non-Storing Modes. This document extends RFC 9010 to enable the 6LR to inject the anycast and multicast addresses in RPL.
