協議

實驗內容

1.利用OSPF動態路由協議完成各個子網網路之間的互聯通訊

2.利用PPP協議的PAP、CHAP認證完成

  2. RouterA和RouteB之間，使用192.168.1.0/24網路;
  3. RouterB和RouteC之間，使用192.168.2.0/24網路;
  4. PC1和RouterC之間，使用172.16.2.0/24網路;
  5. RouteB為DCE裝置，時脈頻率設為64000；

PPP設定要求

  1. RouterA和RouteB之間，使用PAP雙向認證（使用者名稱和密碼自定義）
  2. RouterB和RouteC之間，使用CHAP雙向認證（密碼自定義）

實驗目的

(1)掌握廣域網協議PPP的工作原理

(2)掌握PPP協議的PAP、CHAP認證工作原理

(3)掌握PPP的基本配置

(4)掌握標準ACL的配置；

(5)理解標準ACL在接入控制中的應用

結論：實現了各個子網之間的互聯通訊

下面使用PPP協議的PAP、CHAP完成認證

ppp設定要求：

1.RouterA和RouteB之間，使用PAP雙向認證（使用者名稱和密碼自定義）     

2.RouterB和RouteC之間，使用CHAP雙向認證（密碼自定義）

RouterA：


RouterB:


RouterC:


測試：

結論：RouterA和RouterB之間完成了PAP認證，RouterB和RouterC之間完成了CHAP認證，實現了各個路由器之間的互通。

實驗到此結束！
