一、實驗目標
- 掌握RIP協議的配置方法;
- 掌握查看通過動態路由協議RIP學習產生的路由;
- 熟悉廣域網路線纜的串連方式;
二、實驗背景
假設校園網通過一台三層交換器連到校園網出口路由器上,路由器再和校園外的另一台路由器串連。現要做適當配置,實現校園網內部主機與校園網外部主機之間的相互連信。為了簡化網管的管理維護工作,學校決定採用RIP V2協議實現互連。
三、技術原理
RIP(Routing Information Protocols),路由資訊協議,是應用較早、使用較普通的IGP內部閘道通訊協定,適用於小型同類網路,是距離向量協議;
RIP協議以跳數衡量路徑開銷,RIP協議裡規定最大跳數為15;
RIP協議有兩個版本:RIPv1和RIPv2,RIPv1屬於有類路由協議,不支援VLSM,以廣播形式進行路由資訊的更新,更新周期為30秒;RIPv2屬於無類路由協議,支援VLSM,以組播形式進行路由更新。
四、實驗步驟
實驗拓撲
1、在三層交換器上劃分VLAN10和VLAN20,其中VLAN10用於串連校園網主機,VLAN20用於串連R1;
2、路由器之間通過V.35電纜通過串口串連,DCE端串連在R1上,配置其時間頻率為64000;
3、主機和交換器通過直連線串連,主機與路由器通過交叉線串連;
4、在S3560上配置RIPv2路由協議;
5、在路由器R1、R2上配置RIPv2路由協議;
6、將PC1、PC2主機預設閘道分別設定為與直連網路裝置介面IP地址;
7、驗證PC1、PC2主機之間可以互相通訊;
