第1题：

路由器R1的拓扑连接和地址分配如图1-9所示，如果在R1上安装OSPF协议，运行下列命令：router ospf 200，则配置E0和E1端口的命令分别是(40)。

A．network 10.1.1.0 255.255.255.0 area 0 network 192.168.1.0 255.255.255.0 area 1

B．network 10.1.1.1 255.255.255.0 area 0 network 192.168.1.1 255.255.255.0 area 1

C．network 10.1.1.255 0.0.0.8 area 0 network 192.168.1.255 0.0.0.8 area 1

D．network 10.1.1.0 0.0.0.255 area 0.0.0.0 network 192.168.1.0 0.0.0.255 area 1

正确答案：D
解析：在图1-9所示的网络拓扑结构中，在路由器R1上安装OSPF协议，运行routerospf200启用ID号为200的路由器进程，且进入路由协议的配置子模式。配置OSPF协议时，指定与某一路由器相连的网络的配置命令是“networkaddresswildcard-maskareaarea-id”。其中，“address”字段是指与路由器相连的网段IP地址(注意不是该网段中某个具体的IP地址)；“wildcard-mask”用于指明该网段IP地址的子网掩码的反码；网络区域ID(area-id)一般取数字0～4294967295，也可以用类似IP地址x.x.x.x的表达格式。当网络区域ID为0或0.0.0.0时，说明该网络区域为主干域。不同网络区域的路由器是通过主干域来学习路由信息的。由于路由器R1的e0端口的IP地址为10.1.1.1/24，该IP地址的网络地址为10.1.1.0，“/24”是子网掩码为255.255.255.0的缩写形式，而该子网掩码的反码是0.0.0.255。因此，指定与路由器R1的e0端口相连的网络的配置命令是network10.1.1.00.0.0.255area0.0.0.0。其中“0.0.0.0”表示该网段为主干域。同理，路由器R1的e1端口的IP地址为192.168.1.1/24，该IP地址的网络地址为192.168.1.0，子网掩码为255.255.255.0，该子网掩码的反码是0.0.0.255。因此，指定与路由器R1的e1端口相连的网络的配置命令是network192.168.1.00.0.0.255area1。其中，10.1.1.0是e0所在端口的IP地址，0.0.0.255是255.255.255.0的反向掩码。
