This draft has changes based on the discussion in Dallas and on the list. See below. Based on the discussion I think it also makes sense to add something to make it more clear that hosts which sleep on a schedule will end up missing any unsolicted RAs with new information (and the draft requires certain behavior when such hosts wake up), but that should not be construed as an argument that all hosts can choose to ignore unsolicited RAs. Suggested text is welcome! Erik 14. Change Log Changes since draft-nordmark-6man-rs-refresh-01 of the draft: o Made Refresh Time zero be reserved and RTOs with this value ignored by the receiver. o Removed notion that all-ones refresh time means infinite lifetime. It now means 65535 seconds. o Changed default to be multicast RS refresh, with the option to specify unicast in the RTO. This enables discovering new routers on the link. o Clarified the normative behavior for hosts that sleep on a schedule. o Clarified the updated DNA behavior. o Editorial fixes. -------- Forwarded Message -------- Subject: New Version Notification for draft-ietf-6man-rs-refresh-00.txt Date: Tue, 19 May 2015 10:24:38 -0700 From: internet-drafts@ietf.org To: Andrew Yourtchenko <ayourtch@cisco.com>, Suresh Krishnan <suresh.krishnan@ericsson.com>, Andrew Yourtchenko <ayourtch@cisco.com>, Suresh Krishnan <suresh.krishnan@ericsson.com>, Erik Nordmark <nordmark@acm.org>, Erik Nordmark <nordmark@acm.org> A new version of I-D, draft-ietf-6man-rs-refresh-00.txt has been successfully submitted by Erik Nordmark and posted to the IETF repository. Name: draft-ietf-6man-rs-refresh Revision: 00 Title: IPv6 Neighbor Discovery Optional RS/RA Refresh Document date: 2015-05-19 Group: 6man Pages: 14 URL: https://www.ietf.org/internet-drafts/draft-ietf-6man-rs-refresh-00.txt Status: https://datatracker.ietf.org/doc/draft-ietf-6man-rs-refresh/ Htmlized: https://tools.ietf.org/html/draft-ietf-6man-rs-refresh-00 Abstract: IPv6 Neighbor Discovery relies on periodic multicast Router Advertisement messages to update timer values and to distribute new information (such as new prefixes) to hosts. On some links the use of periodic multicast messages to all host becomes expensive, and in some cases it results in hosts waking up frequently. Many implementations of RFC 4861 also use multicast for solicited Router Advertisement messages, even though that behavior is optional. This specification provides an optional mechanism for hosts and routers where instead of periodic multicast Router Advertisements the hosts are instructed (by the routers) to use Router Solicitations to request refreshed Router Advertisements. This mechanism is enabled by configuring the router to include a new option in the Router Advertisement in order to allow the network administrator to choose host behavior based on whether periodic multicast are more efficient on their link or not. The routers can also tell whether the hosts are capable of the new behavior through a new flag in the Router Solicitations. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org. The IETF Secretariat
