Abstract

   This document specifies how the level 3 multihoming Shim6 protocol
   (Shim6) detects failures between two communicating nodes.  It also
   specifies an exploration protocol for switching to another pair of
   interfaces and/or addresses between the same nodes if a failure
   occurs and an operational pair can be found.
