The IESG has approved the following document: - 'Dynamic Host Configuration Protocol for IPv6 (DHCPv6) bis' (draft-ietf-dhc-rfc3315bis-13.txt) as Proposed Standard This document is the product of the Dynamic Host Configuration Working Group. The IESG contact persons are Suresh Krishnan and Terry Manderson. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-dhc-rfc3315bis/ Technical Summary This document describes the Dynamic Host Configuration Protocol for IPv6 (DHCPv6). It updates the text from RFC3315, the original DHCPv6 specification, and incorporates prefix delegation (RFC3633), stateless DHCPv6 (RFC3736), an option to specify an upper bound for how long a client should wait before refreshing information (RFC4242), a mechanism for throttling DHCPv6 clients when DHCPv6 service is not available (RFC7083), and clarifies the interactions between modes of operation (RFC7550). As such, this document obsoletes RFC3315, RFC3633, RFC3736, RFC4242, RFC7083, and RFC7550. Working Group Summary The dhc WG undertook the development of rfc3315bis to move DHCPv6/RFC3315 to Internet Standard. The process was scoped to do minimal updates to RFC 3315 and incorporate a few core followup RFCs into rfc3315bis for publication as an Internet Standard. The bulk of the work on rfc3315bis was done be a design team, with frequent reports back to the full dhc WG. Because there are some minor protocol changes from previous RFCs in rfc3315bis, and no implementation experience with the protocol as specified in rfc3315bis, the dhc Working Group requests that rfc3315bis be published as Proposed Standard. There were no points or decisions about rfc3315bis that caused controversy or for which consensus was determined to be particularly rough. The origin documents, RFC 3315 et al., were sufficiently well-written and have sufficient implementation and deployment experience to minimize the discussion about rfc3315bis. Document Quality Section 1 summarizes the relationship of rfc3315bis to several RFCs that define the current DHCPv6 specification. Appendix A of rfc3315bis lists the changes in the DHCPv6 specification relative to RFC 3315. rfc3315bis has received significant review by the dhc Working Group in two Working Group last calls. Summaries of the issues raised during the last calls is available at: https://github.com/dhcwg/rfc3315bis/blob/master/wglc-issues-draft-ietf-dhc-rfc3315bis-05.pdf https://github.com/dhcwg/rfc3315bis/blob/master/3315bis%20WGLC%20(draft-ietf-dhc-rfc3315bis-08)%20-%20June%202017%20-%20Sheet1.pdf The Acknowledgments section cites individuals who contributed thorough and helpful reviews. There are no implementations of DHCPv6 that include the changes to the protocol specified in rfc3315bis. There are, of course, many implementations of DHCPv6 based on RFC 3315 and subsequent RFCs. rfc3315bis incorporates updates to the DHCPv6 specification based on interop tests among several DHCPv6 implementations. At least four vendors are interested in updating their implementations: Cisco, Huawei, ISC and Nominum.
