1.  Introduction

   This document describes how LISP handles lookups based on Extended-
   EIDs, i.e. tuples of n elements.  Particularly it describes how the
   Tunnel Routers and the Mapping System operate when Extended-EIDs are
   in place, the different types of Extended-EIDs defined so far, how
   the lookup is performed for each Extended-EID type and which mapping
   databases are recommended to use depending on the kind of Extended-
   EIDs used.
