  Router Advertisement Prefix Option Extension for On-Demand Mobility
                    draft-feng-dmm-ra-prefixtype-03

Abstract

   Router Advertisement / Router Solicitation is one of the ways for
   hosts to establish network IPv6 connectivity configuration.  This
   document describes two approches to allowing a router to specify
   mobility service type availability to mobile hosts.  Mobile hosts can
   then configure their IP address to the preferred type of mobile
   connectivity.  Two possibilities are considered: (i) creating an
   extension to the router advertisement prefix information option to
   allow the router to specify mobility connectivity types, and (ii)
   specifying a new RA options that allows the router to specify the
   mobility connectivity types.

1.  Introduction

   [I-D.ietf-dmm-ondemand-mobility] defines different types of mobility
   related network services provided by access network to mobile hosts.
   In particular, it defines different types of prefix continuity types
   as mobile nodes move between different points of attachments.

   This document proposes two such options to the router advertisement
   message ([RFC4861]) to allow the router to convey mobility services
   associated with an Ipv6 prefix.  The possibilities considered are:
   (i) creating an extension to the router advertisement prefix
   information option to allow the router to specify mobility
   connectivity types, and (ii) specifying a new RA options that allows
   the router to specify the mobility connectivity types.

   For (i), the prefix information option is extended to support the
   specification of mobility type.  In (ii), a new RA option field is
   provided to do the same.
