Hi Robert, Thanks for the quick answer. Re: ORR being expanded in the title: I was hoping to find it expanded somewhere in the body of the document as well, as I seem to remember that’s part of the RFC Editor style guide, but I might remember wrong, and you’ll be able to change that in AUTH48, in case it’s needed. Re: updating RFC4456 – I know that “Update” is an ambiguous header, so I do not want to bikeshed this: the “updates” header does have a flexible meaning, and I just wanted to make sure this had been discussed and decided within the community. Since it has, I am fine with it. But just for your information, “Update” does not necessarily mean “change and obsolete the previously defined spec”. The only meaning I could find is the one defined in https://datatracker.ietf.org/doc/html/rfc2223#section-12 which states: Updates To be used as a reference from a new item that cannot be used alone (i.e., one that supplements a previous document), to refer to the previous document. The newer publication is a part that will supplement or be added on to the existing document; e.g., an addendum, or separate, extra information that is to be added to the original document. I thought this matched well for this doc, which cannot be used alone without 4456, and which just adds to the existing document (without obsoleting it). Anyway, I am fine without it, just wanted to clarify where my comment came from. Thanks, Francesca From: Robert Raszuk <robert@raszuk.net> Date: Wednesday, 16 June 2021 at 16:11 To: Francesca Palombini <francesca.palombini@ericsson.com> Cc: The IESG <iesg@ietf.org>, "draft-ietf-idr-bgp-optimal-route-reflection@ietf.org" <draft-ietf-idr-bgp-optimal-route-reflection@ietf.org>, idr-chairs <idr-chairs@ietf.org>, "idr@ietf. org" <idr@ietf.org>, John Scudder <jgs@juniper.net>, Susan Hares <shares@ndzh.com>, Alvaro Retana <aretana.ietf@gmail.com> Subject: Re: Francesca Palombini's No Objection on draft-ietf-idr-bgp-optimal-route-reflection-25: (with COMMENT) Dear Francesca, Thank you so much for your review of this document. I added most of your suggestions to new version -26 which will be posted soon. On the other two points which perhaps require further clarification: "ORR" is already explained in the title so I removed the hyphen there to make it intuitive that this is the abbreviation for Optimal Route Reflection. As far as updating RFC4456 we have discussed this and the conclusion reached is that this spec is not really an update. Reason being is that in our understanding update is something that changes the previously defined behaviour also in the same time obsoleting it. Here this spec is not replacing traditional route reflection. It adds a new method on path selection for situations where this is applicable and helpful. It is also to be enabled explicitly by configuration. The vanilla RFC4456 will continue to operate just fine for those networks which deployed reflection in the data path or those AFs (AFI/SAFI) which by itself reflect all paths. Please kindly let us know if you are ok with the above explanations.

I have a couple of very minor comments below, and a non blocking question: it seems to me that this document could have contained the "updates" header wrt RFC 4456. Was this considered by the working group? Francesca 1. ----- FP: Please expand AS, POP, SPF, IBGP on first use. 2. ----- The core of this solution is the ability for an operator to specify FP: I would suggest adding the name and abbreviation BGP ORR here, otherwise it comes as a surprise in section 4.
