The IESG has approved the following document: - 'Purge Originator Identification TLV for IS-IS' (draft-ietf-isis-purge-tlv-05.txt) as a Proposed Standard This document is the product of the IS-IS for IP Internets Working Group. The IESG contact persons are Stewart Bryant and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-isis-purge-tlv/ Technical Summary At present an IS-IS purges do 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, the purge-tlv document defines a TLV to be added to purges to record the system ID of the IS generating it. Since normal LSP flooding does not change LSP contents, this TLV should propagate with the purge. This reg-purge draft documents which TLVs can appear in different types of IS-IS PDUs, but does not document which TLVs can be found in zero Remaining Lifetime LSP (a.k.a., purges). This document extends the existing registry to record the set of TLVs that are permissible in purges. Working Group Summary The idea of the purge TLV was first discussed in Dublin at IETF 72. The initial view of the Working Group was that the extension was not necessary. After a couple years of discussion and work on the idea, consensus has been achieved. Document Quality There is one known implementation. Personnel David Ward is the Document Shepherd for this document. Stewart Bryant is the Responsible Area Director. RFC Editor Note ====== In the Abstract OLD Since normal LSP flooding does not change LSP contents, this TLV should propagate with the purge. NEW Since normal Link State Packet (LSP) flooding does not change LSP contents, this TLV should propagate with the purge. This document updates RFC5301, RFC5304 and RFC5310. END ====== In Introduction (para 3) OLD receive a corrupted LSP. NEW receive a corrupted Link State Packet (LSP).
