The IESG has received a request from the Multiprotocol Label Switching WG (mpls) to consider the following document: - 'Relayed Echo Reply mechanism for LSP Ping' <draft-ietf-mpls-lsp-ping-relay-reply-04.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2014-10-13. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract In some inter autonomous system (AS) and inter-area deployment scenarios for RFC 4379 "Label Switched Path (LSP) Ping and Traceroute", a replying LSR may not have the available route to the initiator, and the Echo Reply message sent to the initiator would be discarded resulting in false negatives or complete failure of operation of LSP Ping and Traceroute. This document describes extensions to LSP Ping mechanism to enable the replying Label Switching Router (LSR) to have the capability to relay the Echo Response by a set of routable intermediate nodes to the initiator. This document updates RFC 4379. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-mpls-lsp-ping-relay-reply/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-mpls-lsp-ping-relay-reply/ballot/ The following IPR Declarations may be related to this I-D: http://datatracker.ietf.org/ipr/1945/ http://datatracker.ietf.org/ipr/828/
