#35: 6LoWPAN Prefix Information Option, Length --------------------------------+------------------------------------------- Reporter: [email protected] | Owner: [email protected] Type: enhancement | Status: new Priority: minor | Milestone: Component: nd | Version: Severity: - | Keywords: --------------------------------+------------------------------------------- The length needs to be specified better, comment from Carsten:
> It must be a multiple of 8 because of the way ND options work. > So it could be 0 (rarely useful), 8 (as I argued, useful in many cases), > or 16 (useful for 112-bit prefixes or complete addresses). > > In standard ND, 16 bytes are always sent. > I think the right way to do this is to allow an option length of 1, 2, 3 > (implying 0, 8, 16 bytes for the prefix field) and prohibiting > prefix-length < (length-1) * 64. -- Ticket URL: <http://wiki.tools.ietf.org/wg/6lowpan/trac/ticket/35> 6lowpan <http://tools.ietf.org/6lowpan/> _______________________________________________ 6lowpan mailing list [email protected] https://www.ietf.org/mailman/listinfo/6lowpan
