This has been know and unfortunately has affected *BSD all the back to 2012. It's actually BSD that is not RFC compliant in this case. --snip-- I have not looked that deep. But is the case that FreeBSD does not follow t= he RFC4861 regarding Neighbour Discovery? IF it is not... Then I suggest this will be added to the future ToDo list f= or fixing. --=20 You are receiving this mail because: You are the assignee for the bug.=
