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.
