   This document describes a mechanism for standby status signaling of
   redundant pseudowires (PWs) between their termination points. A set
   of redundant PWs is configured between provider edge (PE) nodes in
   single-segment pseudowire (SS-PW) applications, or between
   terminating provider edge (T-PE) nodes in multi-segment pseudowire
   (MS-PW) applications.

   In order for the PE/T-PE nodes to indicate the preferred PW to use
   for forwarding PW packets to one another, a new status bit is needed
   to indicate a preferential forwarding status of Active or Standby for
   each PW in a redundant set.

   In addition, a second status bit is defined to allow peer PE nodes to
   coordinate a switchover operation of the PW.
