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 {
range6 3ffe:501:ffff:100:200:ff:fe00:abcc 3ffe:501:ffff:100:200:ff:fe00:abcd;
}

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.
