Not sure either. But you could try forcing each VLAN to have a different link-local address and see if it helps. > Giving out addresses with rtadvd is working fine, it's only the > dhcpv6 daemon that cannot give out addresses. I guess it's not working because it does not handle VLAN properly, so it doesn't know where to return the packets to. I might be wrong, but it seems to be the case. > > I've tried both with a manual dhclient -6 (on a linux client) > and with "dispatch" from rtadvd.

There have been some IPv6 changes between 5.6 and 5.7 and even more with -current. So, it might be worth. Cheers, Giancarlo Razzolini
