DHCLIENT not assigning address on interface (IPV6)

Mon Oct 17 06:06:19 UTC 2011

Hi,

I have been trying to test for DHCPV6 network configuration.
But the dhclient is not able to assign address on the interface on
client side...

Please help regarding this issue.

I am pasting all info here..

Here is the Server Config.

root at VPC-1 ~]# cat /etc/dhcpd.conf

subnet 192.168.0.0 netmask 255.255.0.0

{

range 192.168.0.10 192.168.0.20;

}

[root at VPC-1 ~]# cat /etc/dhcpd6.conf

subnet6 3ffe:501:ffff:100:200:ff:fe00:0/112 {

}

As you can see the address is received but not getting assigned on interface...

Please help in solving this problem.. I have DHCPv4 also enabled.
