LSP-Ping is a widely deployed Operation, Administration, and Maintenance (OAM) mechanism in MPLS networks. However, in the present form, this mechanism is inadequate to verify connectivity of a segment of a Multi-Segment Pseudowire (MS-PW) and/or bidirectional co-routed Label Switched Path (LSP) from any node on the path of the MS-PW and/or bidirectional co-routed LSP. This document defines a TLV to address this shortcoming.

For the definition of Stream, see RFC 8729.
