RFC Editor Note

Change fourth paragraph of Section 4:

OLD:

   While IPsec is mandatory with IPv6 [4], considering the power
   constraints and limited processing capabilities of IEEE802.15.4
   devices, IPsec is computationally expensive; Internet key exchange
   (IKEv2) messaging described in [5] is not suited for LoWPANs as the
   amount of signaling in these networks should be minimized.  Thus,
   LoWPANs may need to define their own keying management method that
   requires minimum overhead in terms of packet size and message
   exchange [12].  IPsec provides authentication and confidentiality
   between end nodes and across multiple LoWPAN links, and may be useful
   only when two nodes want to apply security to all exchanged messages.
   However, in many cases, the security may be requested at the
   application layer as needed, while other messages can flow in the
   network without security overhead.
