实验说明
R1,R2,R3实现RIP版本2,之间互相认证配置(方法一)
| R1的配置 |
| ! hostname R1 ! interface FastEthernet0/0 ip address 172.16.0.1 255.255.255.0 ip rip authentication key-chain R1 ip rip authentication mode text //默认是明文认证，如果要使用MD5加密认证,将text换成md5 duplex half ! interface Serial2/1 ip address 192.168.0.1 255.255.255.0 ip rip authentication key-chain R1 serial restart-delay 0 ! key chain R1 key 3 key-string cisco ! router rip version 2 network 172.16.0.0 network 192.168.0.0 ! |
| R2的配置 |
| ! hostname R2 ! interface Serial2/1 ip address 192.168.0.2 255.255.255.0 ip rip authentication key-chain R2 serial restart-delay 0 ! key chain R2 key 10 key-string cisco ! router rip version 2 network 192.168.0.0 |
| R3的配置 |
| ! hostname R3 ! interface FastEthernet0/0 ip address 172.16.0.3 255.255.255.0 ip rip authentication key-chain R3 duplex half ! key chain R3 key 11 key-string cisco ! router rip version 2 network 172.16.0.0 ! |
调试
| R2上进行调试 |
