使用PC机通过路由器访问网址

其间配置DNS,HTTP首先划分两个子网分别是PC（192.168.1.0）和DNS和WEB的网络（192.168.2.0）

IP

pc IP address 192.168.1.1 Subnet Mask 255.255.255.0 Default Gateway 192.168.1.254 DNS Server 192.168.2.1 Server0 DNS IP address 192.168.2.1 Subnet Mask 255.255.255.0 Default Gateway 192.168.2.254 DNS Server 192.168.2.1 Server1 web IP address 192.168.2.2 Subnet Mask 255.255.255.0 Default Gateway 192.168.2.254 DNS Serve1 92.168.2.1

单臂路由器实验

实验需要：6台PC（192.168.1.0）（192.168.2.0）（192.168.3.0）划分子网，vlan技术一台交换机，使得6台机器在3个不同的网络中

单臂路由器的意义是：让不在一个vlan的网络相互通信

这里写图片描述

知识点

show vlan 在#（特权模式下使用）
switchport mode access 设置通路，连接交换机和PC
switchport mode trunk 设置trunk，及设立主干网路
encapsulation dot1Q （4）括号中的数字要与vlan号相匹配
