A Segment Routing (SR) architecture leverages source routing and
tunneling paradigms and can be directly applied to the use of a
Multiprotocol Label Switching (MPLS) data plane.  A node steers a
packet through a controlled set of instructions called "segments" by
prepending the packet with an SR header.

The segment assignment and forwarding semantic nature of SR raises
additional considerations for connectivity verification and fault
isolation for a Label Switched Path (LSP) within an SR architecture.
This document illustrates the problem and defines extensions to
perform LSP Ping and Traceroute for Segment Routing IGP-Prefix and
IGP-Adjacency Segment Identifiers (SIDs) with an MPLS data plane.

This document is a product of the Multiprotocol Label Switching Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this
