DHCPv6 dapat digunakan untuk konfigurasi stateful. Daemon DHCPv6 tidak harus di operasikan di default IPv6 gateway router.

Dengan DHCPv6 kita dapat memberikan lebih banyak informasi daripada menggunakan radvd. Kira-kira hampir sama dengan DHCP Server IPv4.

Setelah di konfigurasi dengan benar, daemon akan beraksi ketika menerima multicast ICMPv6 yang dikirim oleh client ke address ff02::1:2

Konfigfurasi DHCPv6 server (dhcp6s)

Konfigurasi Sederhana

File konfigurasi dhcp6s biasanya berada di /etc/dhcp6s.conf. Contoh sederhana akan tampak sebagai berikut:

interface eth0 {
        server-preference 255;
        renew-time 60;
        rebind-time 90;
        prefer-life-time 130;
        valid-life-time 200;
        allow rapid-commit;
        option dns_servers 2001:db8:0:f101::1 sub.domain.example;
        link AAA {
                range 2001:db8:0:f101::1000 to 2001:db8:0:f101::ffff/64;
                prefix 2001:db8:0:f101::/64;
        };
};

Konfigurasi DHCPv6 client (dhcp6c)

Konfigurasi Sederhana

File konfigurasi dhcp6c biasanya berada di /etc/dhcp6c.conf. Contoh sederhana akan tampak sebagai berikut:

interface eth0 {
        send rapid-commit;
        request domain-name-servers;
};  

Penggunaan

dhcpv6_server

Start server,

# service dhcp6s start

dhcpv6_client

Start client di foreground

# dhcp6c -f eth0

Debugging

dhcpv6_server

The server has one foreground and two debug toggles (both should be used for debugging), here is an example:

# dhcp6s -d -D -f eth0

dhcpv6_client

As general debugging for test whether the IPv6 DHCP server is reable on the link use an IPv6 ping to the DHCP multicast address:

# ping6 -I eth0 ff02::1:2

The client has one foreground and two debug toggles, here is an example:

# dhcp6c -d -f eth0

Oct/03/2005 17:18:17 renew time 60, rebind time 9

Note that the netlink error messages have no impact.
