路由器A和路由器B通过S0/0/0接口直连,路由器A输入配置如下: interface S0/0/0 ip address 9.9.23.3 255.255.255.0 ospf authentication-mode simple cipher 1 如果路由器B要和路由器A形成邻接关系,那么路由器B接口S0/0/0需要输入什么配置?

Ainterface S0/0/0 ip address 9.9.23.4 255.255.255.0 ospf authentication-mode simple cipher 1

Binterface S0/0/0 ip address 9.9.23.4 255.255.255.0 ospf authentication-mode simple plain 1

Cinterface S0/0/0 ip address 9.9.23.4 255.255.255.0 ospf authentication-mode md5 1 plain 1

Dinterface S0/0/0 ip address 9.9.23.4 255.255.255.0 ospf authentication-mode md5 1 cipher 1
