路由器基本配置

dryu999

　　【本实验是为路由器基本配置（2）做准备工作】
　　按照下图，完成网络连通练习。

                        

　　1. 按照IP地址分配表为每台计算机分配IP地址。

设备	端口	IP地址	子网掩码	网关
PC0		192.168.10.10	255.255.255.0	192.168.10.1
PC1		192.168.10.20	255.255.255.0	192.168.10.1
PC2		192.168.20.10	255.255.255.0	192.168.20.1
PC3		192.168.20.20	255.255.255.0	192.168.20.1
ROUTER1	Fa 0/0	192.168.10.1	255.255.255.0
ROUTER1	Fa 0/1	192.168.20.1	255.255.255.0

　　2. 连接网络。
　　3. 为每台计算机配置IP地址。
　　4. 配置路由器。
