2.网络需求
a. R1、R2、R3及R4运行OSPF；
b. 为保证骨干区域area0的安全性，需在area0开启区域认证，使用MD5的认证方式，密码为ht123123；
c. R3与R4之间开启OSPF接口认证，使用明文的认证方式，密码为ht123123；
3配置
在R1上开启area0区域认证：
[R1] ospf 1
[R1-ospf-1 ] area 0
[R1-ospf-1-area-0.0.0.0] authentication-mode md5 1 cipher ht123123
在R2上开启area0区域认证：
[R2] ospf 1
[R2-ospf-1 ] area 0
[R2-ospf-1-area-0.0.0.0] authentication-mode md5 1 cipher ht123123
在R3上开启area0区域认证：
[R3] ospf 1
[R3-ospf-1 ] area 0
[R3-ospf-1-area-0.0.0.0] authentication-mode md5 1 cipher ht123123
在R3上开启接口认证：
[R3] interface GigabitEthernet 0/0/1
[R3-GigabitEthernet0/0/1] ospf authentication-mode simple cipher ht123123
在R4上开启接口认证：
[R4] interface GigabitEthernet 0/0/0
[R4-GigabitEthernet0/0/0] ospf authentication-mode simple cipher ht123123

4.配置完成后，可以做一下查看
5、R3、R4即可基于接口认证建立邻居关系
