Default Could not start a DHCPV6 client successfully

Hello,
I tried to install a DHCPV6 server and client from rpms
on Fedora Core. When staring the client I got many
"enter checking link ..." messages, one after the other, and the IPv6
address was *not* set on the client side.

Any ideas what can it be ?

I am using DHCPV6 from fedora:
https://fedorahosted.org/dhcpv6/wiki

Here are more details:

I have on one machine the dhcpv6 client rpm and on a
second machine the dhcpv6 server.

I acted according to the instructions and copied the dhcp6s.conf and
the /etc/dhcp6c.conf as they are.

log in the DHCPV6 client side:
