实验0015】【利用TFTP服务器备份恢复路由器配置】
【实验名称】利用TFTP服务器备份恢复路由器配置。【实验目的】能够从TFTP服务器备份,并恢复路由器配置。【背景描述】假设某台路由器的配置文件由于误操作或其他某种原因被破坏了,现在需要从TFTP服务器上的备份配置文件中恢复。本实验以1台R1762路由器为例,路由器命名为RouterA。1台PC机通过串口(Com)连接到路由器的控制(Console)端口,通过网卡(NIC)连接到路由器的fastethernet0端口。假设PC机的IP地址和网络掩码分别为37,,路由器的fastethernet1/0端口的IP地址和网络掩码分别为38,。【实验功能】使网络管理员可以备份配置文件,并且将配置恢复到交换机上。【实验设备】R1762(1台)、PC(1台)、直连线(1条)【实验拓扑】
