            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.  Distribution of this 
    memo is unlimited.
