Hi Acee,

I've realized that I yet have not addressed your comment on Section 8 IANA Consideration. Would appreciate your review of update I've prepared (diff and newer version being attached). Updates are in:

·         section 4.2;

·         section 8.4 is now for OSPFv2;

·         new section 8.5 being added for OSPFv3.

We have discussed whether RTM Capability advertisement should be advertised in TE IGP advertisements or use generic IGP. Though this document addresses TE MPLS, I believe that Segment Routing is the use case to support choice of generic IGP advertisements as proposed in the draft.



Greatly appreciate your comments and suggestions.



                Regards,

                                Greg

Hi Greg,

That sounds like a good plan.

Thanks,
