MPLS Label Switched Path Pseudowire Status Refresh Reduction for Static PWs
RFC 8237, “MPLS Label Switched Path Pseudowire Status Refresh Reduction for Static PWs”, is a Proposed Standard document published in October 2017 by L. Martini, G. Swallow, E. Bellagamba. The canonical text is published by the RFC Editor.
Abstract
This document describes a method for generating an aggregated pseudowire (PW) status message transmitted for a statically configured PW on a Multiprotocol Label Switching (MPLS) Label Switched Path (LSP) to indicate the status of one or more PWs carried on the LSP.
The method for transmitting the PW status information is not new; however, this protocol extension allows a Service Provider (SP) to reliably monitor the individual PW status while not overwhelming the network with multiple periodic status messages. This is achieved by sending a single cumulative summary status verification message for all the PWs grouped in the same LSP.
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.
