計算機網絡原理實驗

一、實驗拓撲圖

二、實驗具體要求

1、根據以上拓撲劃分VLAN，嚴格按照標明ＩＰ地址（除路由器與路由器連接段IP 地址按要求更換外）以及設備名稱配置（否則不給分），實現全網的連通。

2、S5700劃分兩個VLAN，VLAN 20、 VLAN 30,其中G0/0/2–5屬于VLAN20 ,G0/0/6–10屬于VLAN 30。

3、AR2220-1 、AR2220-2、AR2220-3路由器通過以太口直連，路由器間利用靜態路由或動態路由RIP實現全網互通。AR2220-1 、AR2220-3連接段IP地址為C類地址塊，第三字節為1XX (XX為班級最后兩位）；AR2220-2 、AR2220-3連接段IP地址為C類地址塊第三個字節為自己的學號后兩位。
例如：班級是1801班，學號為2018100610號的學生 IP網段如下：
192.168.101.0 /24和192.168.10.0/24
　 　
4、在S5700上配置使用用戶名和密碼可遠程登錄，用戶名命名規范如下：
用戶名為自己姓名的漢語全拼，密碼：123456
