The IESG has approved the following document: - 'Invalid TLV Handling in IS-IS' (draft-ietf-lsr-isis-invalid-tlv-03.txt) as Proposed Standard This document is the product of the Link State Routing Working Group. The IESG contact persons are Alvaro Retana, Martin Vigoureux and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-lsr-isis-invalid-tlv/ Technical Summary Key to the extensibility of the Intermediate System to Intermediate System (IS-IS) protocol has been the handling of unsupported and/or invalid Type/Length/Value (TLV) tuples. Although there are explicit statements in existing specifications, deployment experience has shown that there are inconsistencies in the behavior when a TLV which is disallowed in a particular Protocol Data Unit (PDU) is received. This document discusses such cases and makes the correct behavior explicit in order to ensure that interoperability is maximized. Working Group Summary The document was well received and the process straight forward. Document Quality Most implementations already follow what this document specifies. The implementations that do not must be updated. Personnel Document Shepherd: Christian Hopps Responsible AD: Alvaro Retana
