实验-静态路由
拓扑图：
配置需求：
1.如图所示，配置各路由器设备名称，IP地址。
2.如图所示，配置各PC的IP地址、掩码、网关。
3.在R1 R2 R3 R4上配置静态路由，完成以下需求：
1）路由的目标网络号与实际网络号相同
2）采用下一跳的方式配置静态路由（而非出接口）
3）PC1 PC2 PC3互通
4）不得使用默认路由
配置命令：
配置各路由器设备名称，IP地址。

配置完成，进行测试
PC1 与 PC2 通信
出现请求超时错误
这是因为PC1 与 PC2 进行通信时，PC1并不知道R1的mac地址，所以要发起arp广播，arp广播解析时需要时间等待，所以出现超时错误
ping结束后，PC1 上有了关于R1的mac地址解析，所以后续ping操作无需继续解析了
因为PC2是接收方，他在接收到请求后，就需要将请求回复，表明收到了来自于PC1的信息，这时PC2就需要发起ARP请求，找到路由器替自己转发给PC1，所以PC2上也会存在R3的mac地址解析
这时PC3 上面是没有mac地址绑定关系的
这时因为路由器是隔离广播域的，而PC1与PC2进行通信时，发起的广播由R4的路由器进行隔离了，因为R4检测到发起的广播与他没有关系，就不会进行转发，而是丢弃，PC3也就不需要进行arp广播转发回去，所以PC3上是没有mac地址解析的
PC1 与 PC3 通信
同PC2时原理
因为PC3需要回复PC1，表明接收到了请求，所以也发起了arp广播，绑定了来自于R4的mac地址解析
PC2 与 PC3 通信：
因为PC2上已经有了来自于路由器的mac地址，所以不需要再次发起一次arp广播请求，所以可以之间找到路由器，并让路由器进行转发操作
实验完成
总结：
使用命令：
dis ip routing-table 网络号
可以查找当前路由器路由表中，指定的路由
