Hi, all :I could not get NS yet so far. yes , I used a switch to connect all the devices. I did 4 things(all the things was configured ip6mode=autohost in /etc/rc.conf and add "up" in file /etc/ifconfig.interface): 1. didn't use a switch, just used a cross cable between 2 devices, one is netbsd4.0, another was performed to capture tcpdump info. could not get NS 2. all the devices connected to a switch, closed the spanning tree protocol, could not get NS 3. all the devices connected to a switch, closed the spanning tree, and set "sysctl -w net.inet6.ip6.dad_count=3 " or 5 in /etc/rc.local, could not get NS 4. all the devices connected to a switch, closed the spanning tree, installed 4.0.1 and changed NIC card, could not get NS
thanksif we used a very old old machine , maybe we can get link-local NS, but I did not test, because I could not get very old NIC on nowadays I am sure if we used a new machine like hp xw1800 or dell optiplex 745, we could not get link-local NS.
if somebody can get NS to use a new machine, please tell me machine name thanks jiabo Ignatios Souvatzis wrote:

Maybe the two machines don't agree on whether they've auto-negotiated the link before the NetBSD side sends the NS? Can you try with a switch in between, please? Regards, -is
