I am the assigned Gen-ART reviewer for this draft. The General Area Review Team (Gen-ART) reviews all IETF documents being processed by the IESG for the General Area director. Document editors and WG chairs should treat these comments just like any other last call comments. Document: draft-ietf-ospf-prefix-link-attr-10.txt Reviewer: Suresh Krishnan Review Date: 2015-08-13 IETF LC End Date: 2015-08-13 Summary: The draft is almost ready for publication as Proposed Standard but there are some minor issues that need to be addressed. * Section 2 * In the packet format described in Figure "OSPFv2 Extended Prefix Opaque LSA" the numbers 9, 10 and 11 are shown in a field. I think it would be better if these are replaced by the text "LS type" as it is the actual field. This will provide consistency with the rest of the figure. The following text can then describe the allowed LS types as 9,10, and 11. s/differential/differentiate/ * Padding of TLVs. I am assuming that the TLVs are padded using zero octets. If so, please state it explicitly. * Section 2.1. * In the packet format the "Address Prefix" field is marked as variable length when it actually *is not*. It is always encoded as 32 bits long, right? If so please the "(variable)" designation needs to be removed for the Address Prefix. * Shouldn't there be some IANA instructions for further extensions to the Flags field in the OSPFv2 Extended Prefix TLV? Or is this field not expected to be extended? * IANA Considerations * The Opaque LSA Options types used by this document (7 & 8) seem to be wrongly entered into the IANA registry and are pointing to [draft-ietf-ospf-segment-routing-extensions] instead of this draft. It is probably worth taking this up during the IANA check. Thanks Suresh
