Dear All, we've updated references to reflect the PIM WG publishing RFC 9186 <https://datatracker.ietf.org/doc/rfc9186/> and SPRING WG adopting draft-ietf-spring-sr-replication-segment <https://datatracker.ietf.org/doc/html/draft-ietf-spring-sr-replication-segment>, formerly draft-voyer-spring-sr-replication-segment. The authors welcome your comments and questions. Regards, Greg ---------- Forwarded message --------- From: <internet-drafts@ietf.org> Date: Tue, Apr 26, 2022 at 9:42 AM Subject: New Version Notification for draft-ietf-spring-bfd-04.txt To: Mach Chen (Guoyi) <mach.chen@huawei.com>, Greg Mirsky < gregimirsky@gmail.com>, Ilya Varlashkin <Ilya@nobulus.com>, Ilya Varlashkin <ilya@nobulus.com>, Jeff Tantsura <jefftant.ietf@gmail.com>, Jiang Wenying < jiangwenying@chinamobile.com>, <spring-chairs@ietf.org> A new version of I-D, draft-ietf-spring-bfd-04.txt has been successfully submitted by Greg Mirsky and posted to the IETF repository. Name: draft-ietf-spring-bfd Revision: 04 Title: Bidirectional Forwarding Detection (BFD) in Segment Routing Networks Using MPLS Dataplane Document date: 2022-04-26 Group: spring Pages: 14 URL: https://www.ietf.org/archive/id/draft-ietf-spring-bfd-04.txt Status: https://datatracker.ietf.org/doc/draft-ietf-spring-bfd/ Html: https://www.ietf.org/archive/id/draft-ietf-spring-bfd-04.html Htmlized: https://datatracker.ietf.org/doc/html/draft-ietf-spring-bfd Diff: https://www.ietf.org/rfcdiff?url2=draft-ietf-spring-bfd-04 Abstract: Segment Routing (SR) architecture leverages the paradigm of source routing. It can be realized in the Multiprotocol Label Switching (MPLS) network without any change to the data plane. A segment is encoded as an MPLS label, and an ordered list of segments is encoded as a stack of labels. Bidirectional Forwarding Detection (BFD) is expected to monitor any existing path between systems. This document defines how to use Label Switched Path Ping to bootstrap a BFD session, control an SR Policy in the reverse direction of the SR-MPLS tunnel, and applicability of BFD Demand mode in the SR-MPLS domain. Also, the document describes the use of BFD Echo with BFD Control packet payload. The IETF Secretariat
