Abstract

   AAA servers are in use within the Internet today to provide
   authentication and authorization services for dial-up computers.
   Such services are likely to be equally valuable for mobile nodes
   using Mobile IP when the nodes are attempting to connect to foreign
   domains with AAA servers.  AAA servers today identify clients by
   using the Network Access Identifier (NAI). Our proposal defines a way
   for the mobile node to identify itself, by including the NAI along
   with the Mobile IP Registration Request.  This memo also updates RFC
   2290 which specifies the Mobile-IPv4 Configuration option for IPCP,
   by allowing the Mobile Node's Home Address field of this option to be
   zero.
