        Label Switched Path (LSP) Ping for IPv6 Pseudowire FECs
                  draft-ietf-mpls-ipv6-pw-lsp-ping-01

Abstract

   Multi-Protocol Label Switching (MPLS) Label Switched Path (LSP) Ping
   and traceroute mechanisms are commonly used to detect and isolate
   data plane failures in all MPLS LSPs including Pseudowire (PW) LSPs.
   The PW LSP Ping and traceroute elements, however, are not specified
   for IPv6 address usage.

   This document extends the PW LSP Ping and traceroute mechanisms so
   they can be used with IPv6 PWs, and updates RFC 4379.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

Internet-Draft              IPv6 PW LSP Ping              September 2012

1.  Introduction

   Multi-Protocol Label Switching (MPLS) Label Switched Path (LSP) Ping
   and traceroute are defined in [RFC4379].  These mechanisms can be
   used to detect data plane failures in all MPLS Label Switched Paths
   (LSPs) including Pseudowires (PWs).  The PW LSP Ping and traceroute
   elements, however, are not specified for IPv6 address usage.

   Specifically, the PW FEC sub-TLVs for the Target FEC Stack in the LSP
   Ping and traceroute mechanism are defined only for IPv4 Provider Edge
