This liaison is provided for information and to invite your review and feedback, with the objective of ensuring that Mplify considerations are taken into account in the ongoing work. draft-ietf-bess-bgp-sdwan-usage (Now under WG last call in BESS WG - b...@ietf.org) Abstract: This document explores the complexities involved in managing large scale Software Defined WAN (SD-WAN) overlay networks, along with various SD-WAN scenarios. Its objective is to illustrate how a BGP-based control plane can effectively manage these overlay networks by distributing edge service reachability information, WAN port attributes, and underlay path details, thereby minimizing manual provisioning. draft-ietf-idr-sdwan-edge-discovery (WG document in IDR WG - i...@ietf.org) Abstract: The document describes the BGP mechanisms for SD-WAN (Software Defined Wide Area Network) edge node attribute discovery. These mechanisms include a new tunnel type and sub-TLVs for the BGP Tunnel-Encapsulation Attribute [RFC9012] and set of NLRI (network layer reachability information) for SD-WAN underlay information. In the context of this document, BGP Route Reflector (RR) is the component of the SD-WAN Controller that receives the BGP UPDATE from SD-WAN edges and in turn propagates the information to the intended peers that are authorized to communicate via the SD-WAN overlay network. draft-ietf-rtgwg-multisegment-sdwan (WG document in RTGWG WG - rtgwg@ietf.org) Abstract: This document describes a method for seamlessly interconnecting geographically separated SD-WAN segments via a Cloud Backbone without requiring Cloud Gateways (GWs) to decrypt and re-encrypt traffic. By encapsulating IPsec-encrypted payloads within GENEVE headers (RFC 8926), the approach enables Cloud GWs to forward encrypted traffic directly between distant Customer Premises Equipment (CPEs). This reduces processing overhead, improves scalability, and preserves the confidentiality of enterprise data while ensuring secure and efficient multi-segment SD-WAN connectivity. Feedback from Mplify would be valuable to ensure broad applicability and alignment across industry activities. In particular, timely input during the Working Group Last Calls and subsequent IETF Last Calls is especially important, as it ensures that comments can be fully considered and incorporated before the documents advance further in the publication process. We invite Mplify participants to review these documents and provide comments on the relevant WG mailing lists as indicated against each of the documents. Participation in IETF mailing lists is open, and we welcome your input. Sincerely, Gunter Van de Velde Ketan Talaulikar Jim Guichard IETF Routing Area Directors Attachments: No document has been attached _______________________________________________ rtgwg mailing list -- rtgwg@ietf.org To unsubscribe send an email to rtgwg-le...@ietf.org
