 Basic Support for IPv6 over IEEE Std 802.11 Networks Operating Outside
                   the Context of a Basic Service Set
                draft-ietf-ipwave-ipv6-over-80211ocb-52

Abstract

   This document provides methods and settings, for using IPv6 to
   communicate among nodes within range of one another over a single
   IEEE 802.11-OCB link.  Support for these methods and settings require
   minimal changes to existing stacks.  This document also describes
   limitations associated with using these methods.  Optimizations and
   usage of IPv6 over more complex scenarios is not covered in this
   specification and is subject of future work.
