1、网络拓扑如下
2、第一步，创建用户名[R1]aaa[R1-aaa]local-user ssh passwo筠续师诈rd cipher pwd123Info: 帆歌达缒Add a new user.[R1-aaa]local-user ssh privilege level 15[R1-aaa]local-user ssh service-type ssh[R1-aaa]q
3、第二步，开启ssh服务[R1]ssh user ssh authentication-type password //设置SSH用挥年抵遂户的认证方式，默认就是密码认证Authentication type setted, and will be in effect next time [R1]stelnet server enable //开启SSH服务Info: Succeeded in starting the STELNET server.[R1]rsa local-key-pair create //创建本地密钥The key name will be: Host% RSA keys defined for Host already exist.Confirm to replace them? (y/n)[n]:yThe range of public key size is (512 ~ 2048).NOTES: If the key modulus is greater than 512, It will take a few minutes.Input the bits in the modulus[default = 512]:Generating keys.............++++++++++++..............++++++++++++............++++++++..............++++++++[R1]
4、第三部，设置vty认证类型[R1]user-interface vty 0 4[R1-ui-vty0-4]authentication-mode aaa[R1-ui-vty0-4]protocol inbound ssh //设置vty允许ssh登陆
5、Xshell测试在路由器上测试注意需要如下命令[R2]ssh client first-time enable[R2]stelnet 10.10.0.10
