1、拓撲圖

說明：通過配置最終能通過R5 用telnet協議登陸到R4上並將R4改名為R44

2、R4配置

註意：telnet只能在用戶模式上用

創建用戶步驟

1、system-view進入系統模式

2、user-interface vty 0 4 進入vty視圖

3 、允許AAA授權，退出vty

4、進入AAA模式 進入AAA視圖

5、添加用戶 local-user user-telnet password ciper huawei

6、授權用戶級別2+ local-user user-telnet privileges level 2

7、授權用戶可用協議 local-user user-telnet service-type telnet

8、退出

9、從另外一臺路由器登陸測試，前提是IP配置好互相能ping 通
