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.
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
memo is unlimited.
