以上输出最后一行信息表明该接口启用了简单口令认证。

（2）如果 R1 的 s0/0/0 接口启动简单口令认证，R2 的 s0/0/0 接口没有启动认证，则

R2 上出现下面的信息：

*Feb 10 11:19:33.074: OSPF: Rcv pkt from 192.168.12.1, Serial0/0/0 : Mismatch

Authentication type. Input packet specified type 1, we use type 0

（3）如果 R1 和 R2 的 s0/0/0 都启动简单口令认证，但是 R2 的接口下没有配置认证密

码或密码错误，则 R2 上出现下面的信息：

*Feb 10 11:22:33.074: OSPF: Rcv pkt from 192.168.12.1, Serial0/0/0 : Mismatch
