Linux 70% Lab – DHCP with IPv6

先設定一般DHCP功能(不固定發放某IP給特定CLIENT)

Server1：

• yast -i dhcpv6
• vi /etc/sysconfig/network/dhcp6s

做以下修改：
2：DHCP6SIF="eth0"

• vi /etc/dhcp6s.conf

新增以下內容：
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 2002:a78:d01:0:800:27ff:fe03:b3e9 31100173.com;
        link 31100173.com {
                range 2002:a78:d01::1000 to 2002:a78:d01::2000/64;
                prefix 2002:a78:d01::/64;
        };
};

• service dhcp6s start
• chkconfig dhcp6s on

Client1：(建議使用一台新VM)

• yast –i dhcpv6
• yast –> Networking Devices –> Networking Settings –> Edit 要使用的網卡

--> 標定Dynamic Address  選單選DHCP 和 DHCP Version 6 Only
--> Next –>OK

• ifconfig 確認是否取得指定IP

設定發放固定IP給特定Client：

Client1

• vi /var/lib/dhcpv6/client6.leasesxxxxxxxxxxx

開著等下設定會需要參考這裡的內容

Server1：

• vi /etc/dhcp6s.conf

將內容改成：
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 2002:a78:d01:0:800:27ff:fe03:b3e9 31100173.com;
        link 31100173.com {
                range 2002:a78:d01::1000 to 2002:a78:d01::2000/64;
                prefix 2002:a78:d01::/64;
        };
        host client1 {
                 duid ［client1文件中的duid］;
                 iaidinfo {
                      iaid [client1文件名的iaid];
                      renew-time 1000;
                      rebind-time 2000;
                 };
                 address {
                      2002:a78:d01::1688/64;
                      prefer-life-time 2000;
                      valid-life-time 3000;
                 };
            };
};

• service dhcp6s restart

Client1：

• ifconfig 應該已經自動更新為指定的IP
