8. Updating RFC 9010

Ce document met a jour IPv6 Neighbor Discovery et les specifications 6LoWPAN/RPL associees afin qu'un noeud puisse enregistrer un IPv6 prefix aupres de routeurs voisins. Les details de protocole essentiels sont conserves ci-dessous depuis le texte RFC.

8.  Updating RFC 9010

   With [RFC9010]:

   *  The 6LR injects only unicast routes in RPL.

   *  Upon a registration with the R flag set to 1 in the EARO, the 6LR
      injects the address in the RPL unicast support.

   *  Upon receiving a packet directed to a unicast address for which it
      has an active registration, the 6LR delivers the packet as a
      unicast L2 frame to the LLA of the node that registered the
      unicast address.

   This specification adds the following behavior:

   *  Upon a registration with the R flag set to 1 and the P-Field set
      to 3 in the EARO, the 6LR injects the prefix in RPL using a prefix
      RTO.  The P-Field in the RTP MUST be set to 3.

   *  Upon receiving a packet directed to an address that derives from a
      prefix for which it has at least one registration, the 6LR
      delivers a copy of the packet as a unicast L2 frame to the LLA of
      exactly one of the nodes that registered to that prefix, using the
      longest prefix match derivation to find the best 6LN.
