Cisco路由器执行show access-list命令显示如下一组控制列表信息
Standard IP access list 30
deny 127.0.0.0, wildcard bits 0.255.255.255
deny 172.16.0.0, wildcard bits 0.15.255.255
permit any
根据上述信息,正确的access-list配置是()
A.Router (config)#access-list 30 deny 127.0.0.0 255.255.255.0
Router (config)#access-list 30 deny 172.16.0.0 255.240.0.0
Router (config)#access-list 30 permit any
B.Router (config-std-nacl)# access-list 30 deny 127.0.0.0 0.255.255.255
Router (config-std-nacl)# access-list 30 deny 172.16.0.0 0.15.255.255
Router (config-std-nacl)# access-list 30 permit any
C.Router (config)#access-list 30 deny 127.0.0.0 0.255.255.255
Router (config)#access-list 30 deny 172.16.0.0 0.15.255.255
Router (config)#access-list 30 permit any
D.Router (config)#access-list 30 deny 127.0.0.0 0.255.255.255
