    abstract =  {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.},
