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
