I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG.  These comments were written primarily for the benefit of the operational area directors.

Document editors and WG chairs should treat these comments just like any other last call comments.


I think the document is written very clear, except one issue:

Section 4 (page 7) states that (with one exception) extension headers are not examined by any node along the path because fragmentation may cause some fragments not having the complete headers (as described in the RFC7045).


But Section 4.4’s routing header is to indicate a list of intermediate nodes to be “visited”.


Does it mean intermediate nodes need to process the “routing header”?


In Section 4.5 (Fragment Header), I can’t find description on if each fragment should carry the entire Routing Header. If not, the intermediate nodes can’t guarantee all the intermediate nodes specified by the Routing headers will be “visited” by all fragments.
