DHCP6 client

[Brett Lee]

Hello -

Am using FreeBSD 6.3 as a dhcp6 client, trying to get DDNSv6 operational 
in this environment.  When I execute 'dhcp6c -d lnc0' from the command 
line, the following messages are logged on the (ISC 4.1.0p1) DHCP6 server:

Solicit message from fe80::20c:29ff:fef3:a5de port 546, transaction ID 
0xB3D95D
Unable to pick client prefix: no IPv6 prefix pools on this shared network
Sending Advertise to fe80::20c:29ff:fef3:a5de port 546

Am confused by the message above, in particular the "prefix pools", as 
this host obtains the "global address" prefix and configures both link 
local and global addresses via SLAAC.  Surely this can't be the same 
prefix.

Equally confusing is that the Solaris hosts on this LAN have no problem 
getting v6 addresses via this DHCP server, and there seems to be plenty 
of free leases available.

Does FreeBSD 6.3 DHCP6 client need a "prefix", or a "pool" of them to be 
  delivered by the server?  Obviously I'm a little bit confused :) and 
am thinking the problem is with the dhcpd.conf file.  Hoping for some 
clarification or direction.  Configs are below.

Thanks for your guidance/suggestions!  -Brett
