Hello,

I posted version 10 of the eh-limits draft.

Changes include:
- Add requirement for sending hosts to follow recommendations of
RFC8200 for extension header ordering
- Allow hosts and intermediate nodes to enforce RFC8200 extension
header ordering in received packets (this also limits the number of
extension headers)
- Require routers that need to process the transport layer that they
be able to skip over eight extension headers to find the transport
layer header
- Other typos

P{lease review and comment, I believe this draft is about ready to move forward.

Tom

Internet-Draft draft-ietf-6man-eh-limits-10.txt is now available. It is a work
item of the IPv6 Maintenance (6MAN) WG of the IETF.

   Title:   Limits on Sending and Processing IPv6 Extension Headers
   Author:  Tom Herbert
   Name:    draft-ietf-6man-eh-limits-10.txt
   Pages:   16
   Dates:   2023-11-28

Abstract:

   This specification defines various limits that may be applied to
   receiving, sending, and otherwise processing packets that contain
   IPv6 extension headers.  The need for such limits is pragmatic to
   facilitate interoperability amongst hosts and routers in the presence
   of extension headers, thereby increasing the feasibility of
   deployment of extension headers.  The limits described herein
   establish the minimum baseline of support for use of extension
   headers on the Internet.  If it is known that all communicating
   parties for a particular communication, including destination hosts
   and any routers in the path, are capable of supporting more than the
   baseline then these default limits may be freely exceeded.
