draft-shawam-pwe3-ms-pw-protection has been updated to reflect comments
received so far. On reflection, the authors decided that Sasha was correct
in his comment that it would be good to document the linear protection
alternative in the draft. This is in an optional appendix, and implementing
the solution in the main section of the document is required even if the
alternative approach is implemented and used.

Please read and comment to the list.

   In MPLS and MPLS-TP environments, statically provisioned Single-
   Segment Pseudowires (SS-PWs) are protected against tunnel failure via
   MPLS-level and MPLS-TP-level tunnel protection.  With statically
   provisioned Multi-Segment Pseudowires (MS-PWs), each segment of the
   MS-PW is likewise protected from tunnel failures via MPLS-level and
   MPLS-TP-level tunnel protection.  However, static MS-PWs are not
   protected end-to-end against failure of one of the switching PEs
   (S-PEs) along the path of the MS-PW.  This document describes how to
   achieve this protection by updating the existing procedures in RFC
   6870.  It also contains an optional approach based on MPLS-TP Linear
