A network may consist of multiple IGP domains or multiple ASes under the control of same organization. It is useful to have the Label switched Path (LSP) Ping and traceroute procedures when an SR end-to-end path spans across multiple ASes or domains. This document describes mechanisms to facilitae LSP ping and traceroute in inter-AS/inter-domain SR-MPLS networks in an efficient manner with simple Operations, Administration, and Maintenance (OAM) protocol extension which uses dataplane forwarding alone for sending echo reply.}, }
