Purge Originator Identification TLV for IS-IS
RFC 6232, “Purge Originator Identification TLV for IS-IS”, is a Proposed Standard document published in May 2011 by F. Wei, Y. Qin, Z. Li, T. Li, J. Dong. It updates RFC 5301, RFC 5304, RFC 5310. It has since been updated by RFC 8918. The canonical text is published by the RFC Editor.
Abstract
At present, an IS-IS purge does not contain any information identifying the Intermediate System (IS) that generates the purge. This makes it difficult to locate the source IS.
To address this issue, this document defines a TLV to be added to purges to record the system ID of the IS generating it. Since normal Link State Protocol Data Unit (LSP) flooding does not change LSP contents, this TLV should propagate with the purge.
This document updates RFC 5301, RFC 5304, and RFC 5310. [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.
