Revision -00 of this draft was presented at the Toronto IETF and we
received good feedback from the WG. We've updated the draft to incorporate
the received comments. The draft plugs an important hole in resilience for
static MS-PWs. Please review and comment to the list, it's a very quick

   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
