MPLS On-Demand Connectivity Verification and Route Tracing
RFC 6426, “MPLS On-Demand Connectivity Verification and Route Tracing”, is a Proposed Standard document published in November 2011 by E. Gray, N. Bahadur, S. Boutros, R. Aggarwal. It updates RFC 4379. The canonical text is published by the RFC Editor.
Abstract
Label Switched Path Ping (LSP ping) is an existing and widely deployed Operations, Administration, and Maintenance (OAM) mechanism for Multi-Protocol Label Switching (MPLS) Label Switched Paths (LSPs). This document describes extensions to LSP ping so that LSP ping can be used for on-demand connectivity verification of MPLS Transport Profile (MPLS-TP) LSPs and pseudowires. This document also clarifies procedures to be used for processing the related OAM packets. Further, it describes procedures for using LSP ping to perform connectivity verification and route tracing functions in MPLS-TP networks. Finally, this document updates RFC 4379 by adding a new address type and creating an IANA registry. [STANDARDS-TRACK]
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.
