IPv6 DHCP 4.1.0

[Sasha Tchepourko]

Hi,

I've spent some time on this now and can't seem to get any hosts to dhcp 
an ipv6 address...

1. my dhcpd.conf file looks very simple, like this:
+-----------------------------------------------------------------------------+
dhcpv6-lease-file-name "/var/log/dhcpd6.leases";
dhcpv6-pid-file-name "/var/run/dhcpd6.pid";

authoritative;

option dhcp-renewal-time 86400;
option dhcp-rebinding-time 43200;

subnet6 2001:388:3054:10A1::/64 {
        range6 2001:388:3054:10A1::/64;
}
+-----------------------------------------------------------------------------+

2. the router interface is setup as follows:
+-----------------------------------------------------------------------------+
interface Vlan10
 no ip address
 ipv6 address 2001:388:3054:10A1::FF/64
 ipv6 enable
 ipv6 nd managed-config-flag
 ipv6 nd other-config-flag
 ipv6 nd ra suppress
 ipv6 eigrp 1
end
+-----------------------------------------------------------------------------+


3. the dhcp server address is 2001:388:3054:10A1::1 and it's got 
connectivity on the local vlan via link-local addresses (pings local 
router and other hosts). The dhcpd is started with '-6' option for ipv6 
only. The server flavour is FreeBSD 7.0


4. 'tcpdump -nvvvi le0 -p ip6' on the server gives me the following when 
a mac osx leopard is connected to the network and trying to get an address

Any ideas why none of me hosts can get an address?
