On page 25 of
2662bis 07 draft the difficulties for loopback and dad
are
explainded.
Maybe dedection of
loopbacks (of NS) could be supported by adding
a new option either
as NS option or as destination header option.
This option should
carry a random identifier of sufficient length.
All packets having
an address assigned to the interface (or unspecified
address)
as IPv6 source
address and carrying the option with the specified own
identifier would be
discarded as loopbacks.
Best
regards
Peter
