My comments all relate to the 'latter I-D', that is to the extended LSAs YANG model, the one you really want to publish and not to the admin tags (which you will doubtless want to publish in due course).

Simply refreshed before expiration and updated a reference. We really need to publish the extended LSAs YANG model as it is a prerequisite for a lot of drafts.

<tp>
Regarding the latter, I noted back in 2020 that it was a tough read and that has not changed, so I will likely only have the energy to review it once and so will wait for at least WGLC before undertaking such a review.  Meanwhile  I see some editorial glitches but would not appreciate a revised I-D unless and until that WGLC is imminent.

s.1.1 text is out of date

I don’t see a problem in -09.


/opf:ospfv3/ospf:body:
here and elsewhere, what is the final colon doing?

I don’t see this anywhere in the draft.



contact URL is out of date

I’ll update my Email.


references to OSPF YANG need updating to the RFC

This is fixed in -09.



'Figure .. ' now appears in four places, doubtless a 'good idea' from the tool makers.

There is only “Figure 1”.

Thanks,
Acee



Like I say, not justifying a new I-D just yet IMHO.

Tom Petch

Thanks,
Acee

Abstract:
 It is useful for routers in OSPFv2 and OSPFv3 routing domains to be
 able to associate tags with prefixes.  Previously, OSPFv2 and OSPFv3
 were relegated to a single tag and only for AS External and Not-So-
 Stubby-Area (NSSA) prefixes.  With the flexible encodings provided by
 OSPFv2 Prefix/Link Attribute Advertisement and OSPFv3 Extended LSAs,
 multiple administrative tags may be advertised for all types of
 prefixes.  These administrative tags can be used for many
 applications including route redistribution policy, selective prefix
 prioritization, selective IP Fast-ReRoute (IPFRR) prefix protection,
 and many others.

 The ISIS protocol supports a similar mechanism that is described in
 RFC 5130.
