Optimal 6loWPAN Configuration
6LoWPAN Addressing
------------------
The current 6LoWPAN implementation uses only link local, MAC-based
addressing addressing (as discussed in more detail below). Thus if you know
the node addressing, then you know the IPv6 address (and vice-versa)
IPv6 Neighbor Discovery is not supported. The current ICMPv6 and neighbor-
related logic only works with Ethernet MAC. For 6LoWPAN, a
new more conservative IPv6 neigbor discovery is provided by RFC 6775 which
is not currently suppored. With IPv6 neighbor discovery, any IPv6 address
may be associated with any short or extended address. In fact, that is the
whole purpose of the neighbor discover logic: It plays the same role as ARP
in IPv4; it ultimately just manages a neighbor table that, like the arp
table, provides the mapping between IP addresses and node addresses.
The NuttX, Contiki-based 6LoWPAN implementation circumvents the need for
the neighbor discovery logic by using only MAC-based addressing, i.e., the
lower two or eight bytes of the IP address are the node address.
Most of the 6LoWPAN compression algorithms exploit this kind of addressing
to compress the IPv6 address to nothing but a single bit indicating that the
IP address derives from the node address. In this use case, IPv6 neighbor
discover is not useful: If we want to use IPv6 neighbor discovery, we could
dispense with the all MAC based addressing. But if we want to retain the
more compact MAC-based addressing, then we don't need IPv6 neighbor discovery.
However, it would still be nice to have enough in place to support ping6.
Full neighbor support would be necessary if we wanted to route 6LoWPAN frames
outside of the WPAN.
