Hi, All: A new version of Big-TLV document has been posted(https://datatracker.ietf.org/doc/html/draft-wang-lsr-isis-big-tlv), to try to give the community one general way to solve the Big TLV problem.
The main changes from the previous versions are the followings: 1) Add one "Identification" field within the container TLV(type TBD1), to function as the key for any sliced TLV, and is TLV code point independent. 2) Add one "Flag" field, define currently the "F" bit to indicate whether the piece of container is the first piece(F bit is set to 1), or not (F bit is unset) 3) Put all the sliced pieces within the newly defined container TLV(type TBD1). 4) Define some rules for the "Split and Glue" procedures(may be re-optimizer later after the WG discussions) The updated version erases the necessity of defining the "key" information for every IS-IS (Possible Big) TLV code point, and also the necessity of per-TLV capability announcement. Any comments are welcome. Best Regards Aijun Wang On behalf of the co-authors -----邮件原件----- 发件人: [email protected] [mailto:[email protected]] 发送时间: 2024年9月11日 17:31 收件人: Gyan S.

Name: draft-wang-lsr-isis-big-tlv Revision: 00 Title: IS-IS Extension for Big TLV Date: 2024-09-11 Group: Individual Submission Pages: 11 URL: https://www.ietf.org/archive/id/draft-wang-lsr-isis-big-tlv-00.txt Status: https://datatracker.ietf.org/doc/draft-wang-lsr-isis-big-tlv/ HTMLized: https://datatracker.ietf.org/doc/html/draft-wang-lsr-isis-big-tlv Abstract: The IS-IS routing protocol uses TLV (Type-Length-Value) encoding in a variety of protocol messages. The original IS-IS TLV definition allows for 255 octets of value in maximum. This document proposes a solution to IS-IS extension for encoding the TLV whose value is bigger than 255 octets.
