The IESG has received a request from the Dynamic Host Configuration WG (dhc) to consider the following document: - 'Handling Unknown DHCPv6 Messages' <draft-ietf-dhc-dhcpv6-unknown-msg-05.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2014-02-18. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract DHCPv6 is not specific about handling messages with unknown types. This memo describes the problems and defines how a DHCPv6 server, client or relay agent should behave when receiving unknown DHCPv6 messages. This document also provides advice for authors of future documents defining new messages sent from DHCP servers to DHCP relay agents, and should be read by potential authors of such documents. This document updates RFC3315. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-dhc-dhcpv6-unknown-msg/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-dhc-dhcpv6-unknown-msg/ballot/ No IPR declarations have been submitted directly on this I-D.
