Internet-Draft draft-ietf-spring-bfd-10.txt is now available. It is a work item of the Source Packet Routing in Networking (SPRING) WG of the IETF. Title: Bidirectional Forwarding Detection (BFD) in Segment Routing Networks Using MPLS Dataplane Authors: Greg Mirsky Jeff Tantsura Ilya Varlashkin Mach(Guoyi) Chen Jiang Wenying Name: draft-ietf-spring-bfd-10.txt Pages: 15 Dates: 2024-04-17 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 (LSP) Ping to bootstrap a BFD session, optional control of the selection of a segment list as the reverse direction of the BFD session, applicability of BFD Demand mode, and Seamless BFD in the SR-MPLS domain. Also, the document describes the use of the BFD Echo function with the BFD Control packet payload.
