-------------------------------------- You may review the report below and at: https://www.rfc-editor.org/errata/eid6517 -------------------------------------- Status: Verified Type: Technical Reported by: Alexander ("Sasha") Vainshtein <alexander.vainsht...@rbbn.com> Date Reported: 2021-04-05 Verified by: Gunter Van de Velde (IESG) Section: 5 Original Text ------------- Finally, EVPN may employ data-plane egress link protection mechanisms not available in VPWS. This can be done by the primary PE (on local AC down) using the label advertised in the per-EVI Ethernet A-D route by the backup PE to encapsulate the traffic and direct it to the backup PE. Corrected Text -------------- Finally, EVPN may employ data-plane egress link protection mechanisms. This can be done by the primary PE (on local AC down) using the label advertised in the per-EVI Ethernet A-D route by the backup PE to encapsulate the traffic and direct it to the backup PE. Similar behavior for LDP-signaled PWs can be achieved using LDP extensions defined in RFC 8104, but the EVPN-based solution is simpler to implement (e.g., does not require context-specific label spaces) and operate. Notes ----- RFC 8104 "Pseudowire (PW) Endpoint Fast Failure Protection" defines a solution for egress PW endpoint protection that provides fast local protection against failure of the primary egress PE and failure of the Attachment Circuit of this PE, so that the claim that the data-plane egress link protection mechanisms are not available for LDP-signaled PWs is factually inaccurate. However, the solution defined in RFC 8104is much more complicated both from the POV of implementation and from the operational POV, while the EVPN-based solution is quite straightforward. -------------------------------------- RFC8214 (draft-ietf-bess-evpn-vpws-14) -------------------------------------- Title : Virtual Private Wire Service Support in Ethernet VPN Publication Date : August 2017 Author(s) : S.
