Yes, client will generate radvd.conf file and will also configure received 
prefix on the interfaces, which it has received the prefix on.
(that is not the most useful the client can do with a prefix, but it was 
the best from the testing point of view). Also this will be default 
behavior when client's node has IPv6 forwarding disabled.

Anyway, within two weeks client will be able to split received prefix and 
configure subprefixes on its interfaces and generate radvd.conf file. Take 
a look at User's Guide, section 3.6 and especially figure 9. It is 
described there in detail how this will work.

Yes. It will work like this. Clients on your local links will get those
prefixes configured via RADVD.

No, not yet. But such feature will be implemented soon. I think that by 
default this script should restart radvd if it is already running.

Do you have any suggestions related to this behavior?

By the way: I'm going on a business trip. I'll be back on Jan. 15th, so 
dibbler will be on hold for a few days.
