The IESG has approved the following document: - 'Label Switched Path (LSP) Ping for Pseudowire FECs Advertised over IPv6' (draft-ietf-mpls-ipv6-pw-lsp-ping-04.txt) as Proposed Standard This document is the product of the Multiprotocol Label Switching Working Group. The IESG contact persons are Adrian Farrel and Stewart Bryant. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-mpls-ipv6-pw-lsp-ping/ Technical Summary 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. Working Group Summary There is a general agreement in the MPLS WG that some of our protocols need to be extended to meet requirements present in IPv6 networks. This is one of such extension to LSP Ping. There is good support for the document in the MPLS WG. This document updates RFC 4379 that was developed in the MPLS WG and which covers LSPs and pseudowires. Nevertheless, this document was specifically drawn to the attention of the PWE3 WG to ensure cross- review. Document Quality We know of several implementations or intents to implement this draft. Personnel: Loa Andersson (loa@pi.nu) is the document shepherd. Adrian Farrel (adrian@olddog.co.uk) is the responsible AD.
