Linda From: [email protected]<mailto:[email protected]> <[email protected]<mailto:[email protected]>> Sent: Tuesday, December 12, 2023 4:02 AM To: Linda Dunbar <[email protected]<mailto:[email protected]>>; RTGWG ([email protected]<mailto:[email protected]>) <[email protected]<mailto:[email protected]>>; [email protected]<mailto:[email protected]> Subject: RE: WGLC for draft-ietf-rtgwg-net2cloud-problem-statement Hi Linda, all, Thank you for the changes. Below some comments on the candidate version, fwiw: * I think there are "too" much product-specific details. This might be a personal taste but I don't think it is a good idea to have those details in an RFC. [Linda] You are referring to Section 4.1 (Sites to Cloud DC), correct? The intent is to show there are multiple types of Cloud GWs (Internet GW, Virtual GW for terminating IPsec tunnels, and Direct Connect GW for private circuits). The earlier version of the draft only had general term, but comments during the Early DIR review suggested adding some examples. How about changing to the following? "Most Cloud operators offer multiple types of network gateways (GWs)through which an enterprise can reach their workloads hosted in the Cloud DCs: - Internet GW for services hosted in the Cloud DCs to be accessed by external requests via Internet routable addresses. E.g., AWS Internet GW [AWS-Cloud-WAN]. - IPsec tunnels terminating GW for establishing IPsec SAs [RFC6071] with an enterprise's own gateway, so that the communications between those gateways can be secured from the underlay (which might be the public Internet). E.g., AWS Virtual gateway (vGW). - Direct connect GW for enterprises to connect with Cloud services via private leased lines provided by Network Service Providers. E.g., AWS Direct Connect." * The comment in Section 3.6 was not actually about suggesting to add a reference to 8512. I suggest to delete that NEW reference. My main comment was that given that many DCs out there are IPv6-only and DC-SIIT mechanism (RFC7755) is used, check if you can adjust your statement about "usually" assigning private IP addressed. [Linda] My friends working in AWS and Azure all have told me that the adoption of IPv6 for internal private addresses in cloud data centers was not as widespread as the use of IPv4. They are not using RFC7755 to do the IP address translation. Therefore, I don't think we should add this. * In that same section, you changed IP to IPv4/IPv6. I suggest you delete the IPv6 part of that new text and keep the text specific to IPv4. Then, add any IPv6-specific matters in a separate sentence. BTW, absent IPv6-specific discussion in the core text, it is not clear why you included a mention about IPv4/IPv6 when introducing VPCs. [Linda] IPv6 specific discussion is not the intent of this section. The section is about NAT for private address to external. * I still think the classification of your normative references is not OK (e.g., RFC2735 is informative). Please check https://www.ietf.org/about/groups/iesg/statements/normative-informative-references/ [Linda] Thanks. I will change them per the link you gave. * There are some minor nits that weren't echoed from the review (e.g., "of of" in Section 2). [Linda] Will go over again to change the nits. Hope this helps.

This is actually not specific to BGP session, but starts even with basic setup of the underlying bearer/attachment circuit.

Section 3.1 Increased BGP Peering Errors and Mitigation Methods Cloud DCs support more BGP peering than conventional ISPs, which can contribute to increased BGP peering errors such as capability mismatch, unwanted route leaks, missing Keepalives, and errors causing BGP ceases. Capability mismatch can cause BGP sessions not to be adequately established. Those issues are more acute to Cloud DCs than they have traditionally been, even though they may apply to conventional ISPs, just to a lesser degree. Are you saying that Cloud customers using YANG to configure the BGP sessions are less prone to the BGP peering errors identified above?
