  • 第2题:

    在某台Cisco路由器中定义一个名为test的DHCP地址池(192.168.3.0/26),并保留192.168.3.62/29的IP地址。下列正确的配置语句是(29)。

    A.Router(config)#ip dhcp pooltest Router(dhcp-config)#network 192.168.3.00.0.0.63 Router(dhcp-config)#ip dhcp excluded-address192.168.3.62

    B.Router(config)#ip dhcp poo1 test Router(dhcp-config)#network 192.168.3.0255.255.255.192 Router(dhcp-config)#ip dhcp excluded-address 192.168.3.62255.255.255.248

    C.Router(config)#ip dhcp poo1 test Router(dhcp-config)#network 192.168.3.0/26 Router(dhcp-config)#ip dhcp excluded-address 192.168.3.62/29

    D.Router(config)#ip dhcp excluded-address 192.168.3.56192.168.3.62 Router(config)#ip dhcp pool test Router(dhcp-config)#network 192.168.3.0/26


    正确答案:D
    解析:子网地址是DHCP服务器可以分配给DHCP客户的有效IP地址范围。在DHCP Pool配置模式下,使用命令“networknetwork-number>[mask|/prefix-length]”配置IP地址池的子网地址和子网掩码。其中,子网掩码参数允许以两种形式表达,一种形式常见的点分十进制数表达形式(如 255.255.255.192),另一种形式是给出掩码前缀的长度,即掩码位为“1”的个数,如“255.255.255.192”可以写成“/26”。本试题中,配置DHCP地址池192.168.3.0/26的语句如下:
      Router(dhcp-config)#network192.168.3.0255.255.255.192
      或Router(dhcp-contig)#network192.168.3.0/26
      可以在全局配置模式“Router(config)#”下,使用“ip dhcp excluded-address low-address[high-address]”命令将要保留的地址从IP地址池中排除,使之成为不能动态分配的地址。本试题中,需要排除的IP地址范围是192.168.3.62/29。其中,“/29”是子网掩码255.255.255.248的前缀的长度。由于IP地址192.168.3.62的二进制表示是“1100 0000 1010 1000 0000 0011 1110”,其中阴影部分是子网掩码覆盖的比特范围,因此192.168.3.62/29所表达的IP地址范围是192.168.3.56-192.168.3.63。再由于192.168.3.63是 192.168.3.0/26网段的直接广播地址,需要排除,因此保留IP地址范围192.168.3.62/29的配置语句如下:
      Router(config)#ip dhcp excluded-adclress 192.168.3.56 192.168.3.62
      本试题选项A的“ip dhcp excluded-address192.168.3.62”仅排除单个IP地址192.168.3.62。选项B和选项C保留IP地址配置命令所在的配置模式有误,且不允许出现选项B的“ip dhcp exclude_address192.168.3.62 255.255.255.248”和选项C的“ip dhcp excluded-address 192.168.3.62/29”等带有子网掩码的格式。
