The IESG has received a request from the Multiprotocol Label Switching WG (mpls) to consider the following document: - 'Label Switched Path (LSP) Ping/Traceroute for Segment Routing IGP Prefix and Adjacency SIDs with MPLS Data-plane' <draft-ietf-mpls-spring-lsp-ping-09.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-10-06. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract A Segment Routing architecture leverages source routing and tunneling paradigms and can be directly applied to use of a Multi Protocol Label Switching (MPLS) data plane. A node steers a packet through a controlled set of instructions called segments, by prepending the packet with a Segment Routing header. The segment assignment and forwarding semantic nature of Segment Routing raises additional consideration for connectivity verification and fault isolation for an LSP within a Segment Routing architecture. This document illustrates the problem and defines extensions to perform LSP Ping and Traceroute for a Segment Routing network with a MPLS data plane. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-mpls-spring-lsp-ping/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-mpls-spring-lsp-ping/ballot/ No IPR declarations have been submitted directly on this I-D.
