Technically, this looks good. With my IETF Process Wonk hat on, I very much doubt that a BCP is allowed to formally update a standards track document. I suggest discussing that with immediately the AD to avoid much wider debate during IETF Last Call and IESG review. Alternatively, simply remove Updates: 8200. I am not convinced that the draft does truly *update* RFC8200. There is this: > 3. Requirements > > This section lists the normative requirements related to sending and > processing extension headers. The requirements in this section > update the processing requirements specified in Section 4 of > [RFC8200]; in particular, requirements for how many Hop-by-Hop > options an intermediate node must process are updated. but I don't see where section 4 of RFC8200 states how many HbH options a node *must* process. So I think that this BCP does *not* in fact update RFC8200. A more accurate phrase would be: "The requirements in this section augment the processing requirements ..." If agreed, that would resolve my Process Wonk dilemma. Regards Brian On 26-Sep-23 11:17, Tom Herbert wrote: > Hi, > > I posted a new version of the Extension Header Limits draft.
