           SAVI for Mixed Address Assignment Methods Scenario
                         draft-ietf-savi-mix-06

Abstract

   This document reviews how multiple address discovery methods can
   coexist in a single SAVI device and collisions are resolved when the
   same binding entry is discovered by two or more methods.
