2、擬一、 實驗要求1. 實現基于RIP路由協議的程序2. 程序需設計運行界面3. 界面美觀，整潔二、 實驗環境本程序在Windows操作系統環境下，運用visual C+編寫而成，可在任何Windows環境下運行。三、 實驗目的通過本次實驗學習路由協議的工作原理，掌握路由協議的程序編寫，以達到能夠實現路由協議的水平。四、 實驗原理本程序基于路由信息協議RIP（Routing Information Protocol），是內部網關協議IGP中最先得到廣泛使用的協議。RIP是一種分布式的基于距離矢量的路由選擇協議，是因特網的標準協議，RIP路由協議最大優點就是實現簡單，開銷較小。它可以通過不斷地交換

3、信息讓路由器動態的適應網絡連接的變化，這些信息包括每個路由器可以到達那些網絡，這些網絡有多遠等，IGP是應用層協議，并使用UDP作為傳輸協議。RIP協議具有以下特點：（1） RIP是自制系統內部使用的協議及內部網關協議，使用的是距離矢量算法。（2） RIP使用UDP協議的520端口進行RIP進程之間的通信。（3） RIP主要有兩個版本：RIPv1和RIPv2。RIPv1協議的具體描述在RFC 1058中，RIPv2是對RIPv1協議的改進，其協議的具體描述在RFC2453中（4） RIP協議以跳數作為網絡度量值。（5） RIP協議采用廣播或組播進行路由更新，其中RIPv1使用廣播，RIPv2使

4、用組播（224.0.0.9）（6） RIP協議支持主機被動模式，即RIP協議允許主機只接受和更新路由信息而不發送路由信息。（7） RIP協議支持默認路由傳播（8） RIP協議的網絡直徑不超過15跳，適合于中小型網絡，16跳時認為網絡不可達。（9） RIPv1是有類路由協議，RIPv2是無類路由協議，即RIPv2的報文中含有掩碼信息。RIP所使用的路由算法是Bellman-Ford算法。RIP是由“網關消息協議”發展過來的，網關消息協議是RIP的最早的版本。五、 界面設計六、 運行結果1. 點擊啟動開啟路由器2. 在轉發框中設置需要到達的目的網絡3. 點擊計算路由表，程序會自動按照Bellman

5、-Ford算法，計算到達目的網絡的最短路徑，并更新路由表。4. 點擊轉發可顯示到達目的網絡的最短路徑5. 點擊更改拓撲圖，可更換網絡拓撲，本程序共有五種網絡拓撲圖可供選擇。6. 第一種拓撲圖：第二種拓撲圖：第三種拓撲圖：第四種拓撲圖：第五種拓撲圖：七、 總結本程序能夠實現更新路由表，計算最短路徑，轉發路徑信息，更換網絡拓撲，四種功能。八、 附錄：部分源代碼：/ RouteRIPDlg.cpp : implementation file/#include stdafx.h#include RouteRIP.h#include RouteRIPDlg.h#include SetTopology.h
