Zach,
I also don't have any problems with the current multi-hop DAD and don't
want to make any controversial changes that would delay the draft
further than necessary.
FWIW I don't have a problem deferring this discussion until later so we
can get out -12.
I noticed in the title of the message" multi-hop DAD ttl=255 check". I
do think we could send the multi-hop messages with a smaller ttl so
stacks can maintain the rule that a ttl of 255 should never be forwarded.
The ttl check is on the receiver. All of RFC 4861 says that a ND message
(NS, NA, RS, RA, redirect) with ttl != 255 must be discarded by the
receiver. The multi-hop DAD use of NS/NA in 6lowpan-nd is an exception
to that.
