校园ICT技能节比赛题目【2022.5】 介绍：本次实验拓扑以及需求都是根据真实项目进行修改而来；考虑到同学们的学习层次以及进度，对其中部分未涉及的地方进行删减和修改；项目： xxx规划【由于涉及到一些图片隐私的问题，本文此处进行了删减】实验拓扑：比赛要求：IP地址已经规划好，无需考虑IP地址配错问题；打开拓扑文件中的配置文件 rs.net 即可打开拓扑开始考试；在比赛时间内完成实验需求，并且写出实验文档，要求如下：命名规范19网安1-xxx 19云2-张三 19云3-李四格式以word文档的方式提交，按照每个实验要求，在每个要求下面写下自己的配置命令。拓扑介绍：PC7 , PC10属于技术部vlan10，PC8 , PC9属于财务部vlan20；SW1,SW2为接入层设备，负责局域网通讯，并且使用高可靠的方式互联；SW3为Vlan10和Vlan20的网关设备；SW3,R4,R5运行OSPF单域，并且R4，R5分别为联通电信的出口，保证网络的可靠性；其中R6为Inernet互联网设备。实验要求：局域网中存在 Vlan10和Vlan20 两个业务 VLAN，Vlan10 和 Vlan20IP 网段分别对应 192.168.1.0/24 和 192.168.2.0/24，请按需求划分Vlan。[SW1]vlan 10 [SW1‐vlan10] [[SW1‐vlan10]qu [SW1]vlan 20 [SW1‐vlan20]qu [SW1]interface GigabitEthernet 1/0/4 [SW1‐GigabitEthernet1/0/4]port link‐type access
