企业内部DHCP中继实验(结合WindowsDHCP服务器)

公司刚刚搬家，前期时间比较紧急，没时间把IP地址分配做好，利用“基于接口的DHCP”将就。可是后来出现了一些IP冲突的问题。于是就准备搭建一台windows作为局域网的DHCP服务器。因此就有了本次实验。

cloud桥接一台server2008，server2008是安装在VM虚拟机里面的。

利用cloud链接VM虚拟机的server2008服务器，cloud增加两个端口1和2：

• 1用来链接交换机SW5

• 2用来桥接server2008

• Server2008单网卡，设置到vmnet1网络
• Server2008的IP地址设置为192.168.60.100/24，网关：192.168.60.254

在server2008服务器上搭建DHCP服务：添加角色—勾选DHCP，下一步直到完成。

配置三个作用域：分别是vlan10、vlan20、vlan60(服务器)

这里如果搭建两台DHCP可以实现DHCP故障转移。

在SW1上面配置DHCP中继

[SW1-Vlanif10] dhcp relay server-ip 192.168.60.100

[SW1-Vlanif20] dhcp select relay
[SW1-Vlanif20] dhcp relay server-ip 192.168.60.100
[SW1-Vlanif20] q

[SW1]int vlan60
