draft-pkaneria-lsr-multi-tlv-01 is a fine informational read and described the playing field of multi-part tlv’s well.
I am having troubles understanding the value of ‘The Multi-part TLV Capability’ flag. What would break if ‘Multi-part TLV Capability’ flag would not exist? IS-IS has been working well for many years. Why would that suddenly change and mandate existence and complexity of a ‘Multi-part TLV Capability’ flag? G/ Note: thoughts about the flag: What if a system by accident sends flip-flopping (set/unset/set/unset/etc) of this flag? What if an advertising system support multi-tlv for TLV ‘A’ but not for TLV ‘B’?

A diff is attached. Most of this is a change to terminology to stop using the word ‘instance’ and shift to using ‘multi-part TLV’. We have been having a discussion about adding more discussion of keys in this document. We have not done that yet. This is not an indication of refusal, just making one baby step forward. More to come… Text contributions are more than welcome. Other comments?

Name: draft-pkaneria-lsr-multi-tlv Revision: 01 Title: Multi-part TLVs in IS-IS Document date: 2022-07-04 Group: Individual Submission Pages: 7 URL: https://www.ietf.org/archive/id/draft-pkaneria-lsr-multi-tlv-01.txt Status: https://datatracker.ietf.org/doc/draft-pkaneria-lsr-multi-tlv/ Htmlized: https://datatracker.ietf.org/doc/html/draft-pkaneria-lsr-multi-tlv Diff: https://www.ietf.org/rfcdiff?url2=draft-pkaneria-lsr-multi-tlv-01 Abstract: New technologies are adding new information into IS-IS while deployment scales are simultaneously increasing, causing the contents of many critical TLVs to exceed the currently supported limit of 255 octets. Extensions such as [RFC7356] require significant IS-IS changes that could help address the problem, but a less drastic solution would be beneficial. This document codifies the common mechanism of extending the TLV content space through multiple TLVs. The IETF Secretariat
