Abstract

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. Segment Routing also provides an easy and efficient way to provide inter connectivity in a large scale network as described in [RFC8604]. [RFC8287] 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. It is useful to have the LSP Ping and traceroute procedures when an SR end-to-end path spans across multiple ASes. This document describes mechanisms to facilitae LSP ping and traceroute in inter-AS SR networks in an efficient manner with simple OAM protocol extension which uses dataplane forwarding alone for sending Echo-Reply.
