The IESG has approved the following document: - 'IS-IS Registry Extension for Purges' (draft-ietf-isis-reg-purge-01.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-reg-purge/ Note that I have re-issued a LC on this document in response to the following Gen-Art Note "Procedural concern: The last call did not included the note that for historical reasons the registry this document updates was established by an Informational RFC (RFC 3563) and therefore this Proposed Standard has a normative dependence upon that Informationl RFC. (The downref notice.) I can not imagine anyone objecting to the downref, but I thought our procedures require that the notice be included. " 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 RFC 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 RFC extends the existing registry to record the set of TLVs that are permissible in purges. Working Group Summary This document has working group consensus. 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 Please add at the end of the abstract: This document updates RFC3563, RFC5304 and 5310. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
