[上課筆記] RIP動態路由協定

**本練習題不做.pka檔,因需自行判斷網路是否完成設定

1. 請依圖示完成Router與PC之IP設定(本練習Switch暫時不設管控IP)
2. 請於三顆Router啟動RIPv1，觀察是否能正常運作？若不行，請問解決方案為何？請執行之。

3. 請判斷三顆Router是否都有些介面無須傳遞RIP更新？請使用passive-interface的方式將其RIP update關閉。

4.請判斷環境中是否需要設定預設路由？若需要，請設定之？

5.請測試每一台PC皆可ping到200.200.200.1這一台web server。

看到這題目，先把最簡單的幹掉吧！把兩台ＰＣ的ＩＰ先設定好後，我們再來談討題目

這題的指令碼似乎很長，但實際上與前面所曾做過的LAB差不多，只是多一個RIP協定，只要前幾次的作業很熟，這一次的也不難到哪哩，多參入幾行數據而已，話不多說，直接設定三顆Router吧，一樣透過指令碼與註解的搭配，迅速了解要做什麼～

• R1(config-if)#exit //這裡以上都是設定介面IP
• R1(config)#ip route 0.0.0.0 0.0.0.0 s0/2/0 //別忘了對外的Router需要手動設定對外的靜態預設路由
• R1(config)#router rip //開始設定動態協定RIP
• R1(config-router)#version 2 //這裡我們使用RIP是為了要支援CIDR與更新Default Route
• R1(config-router)#network 192.168.1.0 //輸入鄰接的網域，採用Class級別
• R1(config-router)#no auto-summary //當你發現網域非唯一使用，在其他末端也有相同網域，就取消他的合併功能，因為會認為是送到同一個末端，進一步採取風險處理方式兩邊都各傳一半，造成實際上失誤率50%。
• R1(config-router)#passive-interface s0/2/0 //開啟RIP會將自己的路由表丟給附近的設備，但部分設備根本看不懂該資訊，如Switch與不理你的ISP業者，故為了保護機密要把這些介面給關掉，亦可解省封包阻塞。
• R1(config-router)#redistribute static //rip是動態而Default Route是靜態，開啟可以動靜態一起分享

完成之後，隨便找一台PC對ISP下Ping指令看看吧
