Hi WG, We have submmitted https://datatracker.ietf.org/doc/draft-chen-bess-evpn-wtr-on-fast-df-recovery/. In this draft, the SCT-EC is extended to the A-D per EVI routes, so that the ingress PEs can perform the revertive FRR switching based on the time specified by the SCT-EC for the non-adjacent ESes that support the fast DF recovery. Any comments are welcome. Best Regards, Ran Original From: internet-drafts@ietf.org <internet-drafts@ietf.org> To: 陈然00080434;王玉保10045807; Date: 2023年07月10日 19:22 Subject: New Version Notification for draft-chen-bess-evpn-wtr-on-fast-df-recovery-00.txt A new version of I-D, draft-chen-bess-evpn-wtr-on-fast-df-recovery-00.txt has been successfully submitted by Yubao Wang and posted to the IETF repository. Name: draft-chen-bess-evpn-wtr-on-fast-df-recovery Revision: 00 Title: WTR signaling on Fast DF Recovery of Single-Active ESIs Document date: 2023-07-10 Group: Individual Submission Pages: 9 URL: https://www.ietf.org/archive/id/draft-chen-bess-evpn-wtr-on-fast-df-recovery-00.txt Status: https://datatracker.ietf.org/doc/draft-chen-bess-evpn-wtr-on-fast-df-recovery/ Html: https://www.ietf.org/archive/id/draft-chen-bess-evpn-wtr-on-fast-df-recovery-00.html Htmlized: https://datatracker.ietf.org/doc/html/draft-chen-bess-evpn-wtr-on-fast-df-recovery Abstract: The non-DF of a Single-Active Ethernet Segment (SA-ES) can filter both unicast traffic and BUM traffic. In such case, when a specific Single-Active ES performs fast DF recovery, the corresponding revertive FRR switching should be performed on the ingress PEs that are not adjacent to this ES. This revertive FRR switching needs to be performed immediately after the A-D per EVI route with the "P=1" is received from the new DF node. In other words, the revertive FRR switching cannot perform the WTR procedures, otherwise unicast traffic will be dropped on the new NDF node during the WTR. In this draft, the SCT-EC is extended to the A-D per EVI routes, so that the ingress PEs can perform the revertive FRR switching based on the time specified by the SCT-EC for the non-adjacent ESes that support the fast DF recovery.
