dhcp6 client receives lease but interface doesn't get configured

[Mike Cross]

Hi,

I'm running dhcp-4.1.1b1 server and clients.  I'm finding that my client is
getting a lease, but it doesn't get configured as an address on the
interface.

So here's my server config:

##
default-lease-time 2592000;
preferred-lifetime 604800;
option dhcp-renewal-time 3600;
option dhcp-rebinding-time 7200;
allow leasequery;
option dhcp6.name-servers 2001:4978:245::1;
option dhcp6.domain-search "digitalsushi.com";
option dhcp6.preference 255;
option dhcp6.info-refresh-time 21600;
dhcpv6-lease-file-name "/usr/local/var/db/dhcpd6.leases";

subnet6 2001:4978:245::/64 {
    range6 2001:4978:245::20 2001:4978:245::22;
}
##

I start the server up with
/usr/local/sbin/dhcpd -cf /usr/local/etc/dhcpd-dhcpv6.conf -6 -d -f -tf eth1

Then on my client, another physical machine, I run
/usr/local/sbin/dhclient -6 -d -cf /dev/null eth0
and get this output:

That seems good.. but ifconfig doesn't show that address on the interface.
Is there some /proc/sys/net/ipv6/conf bit I need to flip?  Nothing looked
very good in there.   This is kinda like getting a new toy and not having an
adult around to open the plastic wrap.

Hey, thanks for reading.
