I was trying to add a particular link-local and when I couldn't get the non_eui64 config in the rc.conf file to work I was just manually adding the link-local in the rc.conf file (also changing auto_linklocal to be '0'). I wasn't putting a /prefix_len at the end of the address. I changed that (to ipv6_ifconfig_fxp1="fe80::abcd/64"), rebooted, and now when I do the network_ipv6 restart I see the NSs go out. Strange. Maybe you have to specify the prefix length? ----- Forwarded by Christy L Norman/Rochester/IBM on 02/07/2008 11:49 AM ----- Christy L Norman/Rochester/IBM 02/07/2008 11:42 AM To users@tahi.org cc Subject Re: [users:00573] Re: FreeBSD 5.4 & DAD I'm not seeing them at all. I've tried: ifconfig fxp1 down/up, /rc.d/network_ipv6 restart, /netif/restart and rebooting. I even tried upping the sysctl value for the # of DAD transmits to 2 and still see sent. It does send the NA if someone sends an NS though.

FreeBSD does not seem to perform DAD when an interface is brought down administratively (ifconfig) and then brought back up. It performs DAD on boot though, or when a new IPv6 address is added to an interface. Are you seeing similar problems?
