Hi,

I agree with Les.  I think the draft should be recast to indicate that it is providing OSPF parity with RFC 7794.
Can’t topology discovery be done using RFC 7770?

Yours Irrespectively,

John

Subject: Re: [Lsr] Working Group Adoption Poll for "OSPF Extension for Prefix Originator" - draft-wang-lsr-ospf-prefix-originator-ext-01

To the extent that the draft defines functionality equivalent to that defined in IS-IS RFC 7794 – specifically a means to advertise the source router-id of a given advertisement – it defines a necessary and useful extension to the OSPF protocol – and I support that work.

However, in its current form the draft discusses use of this mechanism for inter-area topology discovery. This idea is seriously flawed – as has been discussed extensively on the WG list.
The draft also discusses uses cases related to ERLD, the direction for which is very much uncertain at this time.

I therefore feel that the current content of the draft is not what I would expect to see approved by the WG as an RFC and therefore have significant reservations about moving forward with the existing content.

I do want to see a draft addressing the source router-id advertisement gap move forward – and if this draft is reduced to focus on that then I can enthusiastically support adoption – but in its current form I cannot indicate support.

   Les

This begins a two week adoption poll for the subject draft. Please send your comments to this list before 12:00 AM UTC on Thursday, February 28th, 2019.

All authors have responded to the IPR poll and there is one  https://datatracker.ietf.org/ipr/search/?submit=draft&id=draft-wang-lsr-ospf-prefix-originator-ext<https://urldefense.proofpoint.com/v2/url?u=https-3A__datatracker.ietf.org_ipr_search_-3Fsubmit-3Ddraft-26id-3Ddraft-2Dwang-2Dlsr-2Dospf-2Dprefix-2Doriginator-2Dext&d=DwMGaQ&c=HAkYuh63rsuhr6Scbfh0UjBXeMK-ndb3voDTXcWzoCI&r=CRB2tJiQePk0cT-h5LGhEWH-s_xXXup3HzvBSMRj5VE&m=yONjTFGQ4o2Kn4-71l1WNkaIh-ck54I626wsy_xfbfM&s=QSvTQLLyqhq6OcKx4iGyD3Xp7jvD_Hc_t03Lvct3CJE&e=>
