Hi Matthew,
my apologies for the belated response:
I am still awaiting a response from our product team on whether any part of the
draft is supported.
I concur with Ali. LSP Ping is a broadly used OAM tool detecting and localizing
failures, including discrepancies between the data and control planes. The
document defines necessary Target FEC sub-TLVs for EVPN and MVPN cases.

Hi Matthew,
Some of the co-authors are on PTO and I couldn’t reach them (typical of the
month of August). So, I’d like to get a bit more extension.
Regarding the two questions below:
My company hasn’t implemented it.
I do think that we should process with the publication as it describes how LSP
ping can be used to detect data-plane failures for various EVPN functionality
including aliasing, split-horizon filtering using ESI label, multicast,
l2-unicast, l3-unicast, IRB, etc. For MPLS transport tunnel, I am not aware of
any other tool/draft that allows us to do data-plane failure detection. Thus, I
think it is important to proceed with its publications.
Still I’d like to hear from other co-authors and other people in this community.
Regards,
Ali

Subject: Implementation poll for draft-ietf-bess-evpn-lsp-ping-05
WG and Authors
Unfortunately I have not seen any responses indicating that there are any
known implementations of this draft. I also did not see any responses to
Stephane's question if we should proceed regardless.
As per the BESS WG implementation policy
(https://mailarchive.ietf.org/arch/msg/bess/cG3X1tTqb_vPC4rg56SEdkjqDpw/),
please can you respond to this email indicating either:
- That you are aware of any implementations (ideally providing some details)
- If you are not aware of any, if you think the WG should proceed with the
draft's publication and why.
I will close this poll on 25th August 2021.
Regards
Matthew

Abstract:
LSP-Ping is a widely deployed Operation, Administration, and
Maintenance (OAM) mechanism in MPLS networks. This document
describes mechanisms for detecting data-plane failures using LSP Ping
in MPLS based EVPN and PBB-EVPN networks.
