Title: Invalid TLV Handling in IS-IS Author: L. Ginsberg, P. Wells, T. Li, T. Przygienda, S. Hegde Status: Standards Track Stream: IETF Date: September 2020 Mailbox: ginsb...@cisco.com, pauwe...@cisco.com, tony...@tony.li, p...@juniper.net, shrad...@juniper.net Pages: 8 Updates: RFC 5305, RFC 6232 I-D Tag: draft-ietf-lsr-isis-invalid-tlv-03.txt URL: https://www.rfc-editor.org/info/rfc8918 DOI: 10.17487/RFC8918 The 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 that 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. This document updates RFCs 5305 and 6232. This document is a product of the Link State Routing Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
