Return Path Specified Label Switched Path Ping
RFC 7110, “Return Path Specified Label Switched Path Ping”, is a Proposed Standard document published in January 2014 by M. Chen, W. Cao, S. Ning, F. Jounay, S. Delord. It has since been updated by RFC 7737. The canonical text is published by the RFC Editor.
Abstract
This document defines extensions to the data-plane failure-detection protocol for Multiprotocol Label Switching (MPLS) Label Switched Paths (LSPs) known as "LSP ping". These extensions allow a selection of the LSP to be used for the echo reply return path. Enforcing a specific return path can be used to verify bidirectional connectivity and also increase LSP ping robustness.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
