This document updates the 6LoWPAN extensions to IPv6 Neighbor Discovery (RFC 8505) to enable a node that owns or is directly connected to a prefix to register that prefix to neighbor routers. The registration indicates that the registered prefix can be reached via the advertising node without a loop. The prefix registration also provides a protocol-independent interface for the node to request neighbor router(s) to redistribute the prefix to the larger routing domain using their specific routing protocols. As an example, this document extends RFC 9010 to enable the 6LR to inject the registered prefix in RPL.
