IPv6 Server: Dynamic Host Configuration v6 Server (dhcp6s)

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
