Hi Matthew, my apologies for the belated response: 1. I am still awaiting a response from our product team on whether any part of the draft is supported. 2. 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.

Be cautious of content] 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: 1. My company hasn’t implemented it. 2. 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.
