第3题:

某园区网采用 OSPF路由协议,参与 OSPF的网络地址是 169.111.0.0/16, Cisco路由器的正确配置是 ( ) 。

A) Rounter(config)# router ospf63

Rounter(config-router)# network 169.111.0.0 0.0.0.0 area 0

Rounter(config_router)# area o range 169.111.0.0 255.255.0.0

B) Rounter(config)# router ospf63

Rounter(config-router)# network 169.111.0.0 255.255.0.0 area 0

Rounter(config-router)# area o range 169.111.0.0 255.255.0.0

C) Rounter(config)# router ospf63

Rounter(config-router)# network 169.111.0.0 0.0.255.255 area 0

Rounter(config_router)# area o range 169.1-11.0.0 255.255.0.0

D) Rounter(config)# router ospf63

Rounter(config_router)# network 169.111.0.0 0.0.255.255 area 0

Rounter(config-router)# area o range 169.111.0.0 0.0.255.255


正确答案:C
(23)C) 【解析】在全局配置模式下,使用“router ospf ”命令,启动OSPF进程:在路由器的OSPF配置模式下,使用“network ip<子网号> area<区域号>”命令定义参与OSPF的子网地址,或使用“area<区域号>range<子网地址><子网掩码>”命令定义某一特定范围子网的聚合。由于network 命令中的是子网掩码的反码,所以本题选项c)正确。
