Technical Summary
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.
Finally, this document updates the PW operational status textual
convention defined in RFC 5542.
