Hi all, A new version of the draft https://datatracker.ietf.org/doc/draft-wang-bess-mvpn-upstream-df-selection/ is published, in which the root PEs differentiation issue of UMH route and dual-root protection issue in Segmented Inter-AS Scenario are resolved. We are looking forward to more comments, it would be appreciated if you can give some valuable suggestions to help us evolve it further . Regards, Siyu Chen

Name: draft-wang-bess-mvpn-upstream-df-selection Revision: 03 Title: Multicast VPN Upstream Designated Forwarder Selection Document date: 2022-11-21 Group: Individual Submission Pages: 16 URL: https://www.ietf.org/archive/id/draft-wang-bess-mvpn-upstream-df-selection-03.txt Status: https://datatracker.ietf.org/doc/draft-wang-bess-mvpn-upstream-df-selection/ Htmlized: https://datatracker.ietf.org/doc/html/draft-wang-bess-mvpn-upstream-df-selection Diff: https://www.ietf.org/rfcdiff?url2=draft-wang-bess-mvpn-upstream-df-selection-03 Abstract: This document defines Multicast Virtual Private Network (VPN) extensions and procedures of designated forwarder election performed between ingress PEs, which is different from the one described in [RFC9026] in which the upstream designated fowarder determined by using the "Standby PE Community" carried in the C-Multicast routes. Based on the DF election, the failure detcetion point discovery mechanism between DF and standby DF is extended in MVPN procedures to achieve fast failover by using BFD session to track the status of detection point. To realize a stable "warm root standby", this document obsolete the P-Tunnel status determining procedure for downstream PEs in regular MVPN by introducing an anycast RPF checking mechanism in dataplane as an instead.
