A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Dynamic Host Configuration WG of the IETF. Title : Softwire Provisioning using DHCPv4 Over DHCPv6 Authors : Ian Farrer Qi Sun Yong Cui Linhui Sun Filename : draft-ietf-dhc-dhcp4o6-saddr-opt-08.txt Pages : 17 Date : 2018-11-12 Abstract: DHCPv4 over DHCPv6 (RFC7341) is a mechanism for dynamically configuring IPv4 for use as an over-the-top service in a 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., RFC7596 or RFC7597), the operator needs to know the IPv6 address that the client will use as the source of 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 (RFC7598) describes a deterministic DHCPv6 based mechanism for provisioning softwires. This document updates "DHCPv6 Options for Configuration of Softwire Address and Port-Mapped Clients" (RFC7598), allowing OPTION_S46_BR (90) to be enumerated in the DHCPv6 client's Option Request Option (ORO) request and appear directly within subsequent messages sent by the DHCPv6 server.
