Last Call Review of draft-ietf-6man-rfc2460bis-08
I have been selected as the Routing Directorate reviewer for this draft. The Routing Directorate seeks to review all routing or routing-related drafts as they pass through IETF last call and IESG review, and sometimes on special request. The purpose of the review is to provide assistance to the Routing ADs. For more information about the Routing Directorate, please see http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir
Although these comments are primarily for the use of the Routing ADs, it would be helpful if you could consider them along with any other IETF Last Call comments that you receive, and strive to resolve them through discussion or by updating the draft.

Intended Status: Standards Track
I have some minor comments about this document that I think might have to be resolved before publication.
No major issues found.
Section 4.4: processing of the "segment left" field is left undocumented (shouldn't it be decremented after being processed ?)
Section 4.5: "If insufficient fragments are received to complete reassembly" does "insufficient" means the last fragment ?
Section 4.8: states "New hop-by-hop options are not recommended because nodes may be configured to ignore the Hop-by-Hop Option header, drop packets containing a hop-by-hop header" does this configuration change because options are new or old ? there seems to be confusion here between "new vs. existing" options and "intermediate nodes MAY be configured to ignore/drop packets with these options included".
Section 8.3: one would have expected a self-consistent formula to determine the max.payload size instead of a relative comparison to IPv4
Section 8.4: automatically reversed or not, this section doesn't state if the response (understood here that the option type is recognized) is to be sent to the source address (directly) or the last entry from the record route for instance (cf. Section 4.4).
