三層交換機動態路由

實驗二十九（1）、三層交換機RIP 動態路由

1、 實驗目的

一、掌握三層交換機之間經過RIP 協議實現網段互通的配置方法。

二、理解動態實現方式與靜態方式的不一樣

2、 應用環境

當兩臺三層交換機級聯時，爲了保證每臺交換機上所鏈接的網段能夠和另外一臺交換機上

鏈接的網段互相通訊，使用 RIP 協議能夠動態學習路由。

3、 實驗設備

一、DCRS-7604（或 6804）交換機 1 臺

二、DCRS-5526S交換機 1 臺

三、PC機 2-4 臺

四、Console 線1-2 根

五、直通網線 2-4 根

4、 實驗拓撲

5、 實驗要求

一、在交換機A 和交換機B 上分別劃分基於端口的VLAN：

交換機A 10 1~8

20 9~16

100 24

交換機B 30 1~8

40 9~16 101 24

二、交換機A 和B 經過的24 口級聯。
