A new Request for Comments is now available in online RFC libraries. RFC 8539 Title: Softwire Provisioning Using DHCPv4 over DHCPv6 Author: I. Farrer, Q. Sun, Y. Cui, L. Sun Status: Standards Track Stream: IETF Date: March 2019 Mailbox: ian.farrer@telekom.de, sunqi.ietf@gmail.com, yong@csnet1.cs.tsinghua.edu.cn, lh.sunlinh@gmail.com Pages: 18 Characters: 39504 Updates: RFC 7598 I-D Tag: draft-ietf-dhc-dhcp4o6-saddr-opt-08.txt URL: https://www.rfc-editor.org/info/rfc8539 DOI: 10.17487/RFC8539 DHCPv4 over DHCPv6 (RFC 7341) is a mechanism for dynamically configuring IPv4 for use as an over-the-top service in an IPv6-only network. Softwires are an example of such a service. For DHCPv4 over DHCPv6 (DHCP 4o6) to function with some IPv4-over-IPv6 softwire mechanisms and deployment scenarios (e.g., RFC 7596 or RFC 7597), the operator needs to know the IPv6 address that the client will use as the source of an IPv4-in-IPv6 softwire tunnel. This address, in conjunction with the client's IPv4 address, and (in some deployments) the Port Set ID are used to create a binding table entry in the operator's softwire tunnel concentrator. This memo defines a DHCPv6 option to convey IPv6 parameters for establishing the softwire tunnel and a DHCPv4 option (to be used only with DHCP 4o6) to communicate the source tunnel IPv6 address between the DHCP 4o6 client and server. It is designed to work in conjunction with the IPv4 address allocation process. "DHCPv6 Options for Configuration of Softwire Address and Port-Mapped Clients" (RFC 7598) describes a deterministic DHCPv6-based mechanism for provisioning softwires. This document updates RFC 7598, allowing OPTION_S46_BR (90) to be enumerated in the DHCPv6 client's Option Request Option (ORO) request and to appear directly within subsequent messages sent by the DHCPv6 server. This document is a product of the Dynamic Host Configuration Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol. Distribution of this memo is unlimited. This announcement is sent to the IETF-Announce and rfc-dist lists.
