计算机网络实验(思科模拟器Cisco Packet Tracer)配置静态路由使三台pc机网络互通

如何配置静态路由?设备:三台路由器、三台交换机、三台pc机要求:任意两台pc机之间都能ping通拓扑图如下pc机配置pc1IP:192.168.10.1Mask:255.255.255.0Gateway:192.168.10.254pc2IP:192.168.20.1Mask:255.255.255.0Gateway:192.168.20.254pc3IP:192.168.30.1Mask:255.255.255.0Gateway:192.168.30.254路由器配置router0router1router2静态路由配置其实很简单,先看直连路由有没有这条路由,没有就添加配置静态路由一看你要到

Packet Tracer - 配置初始路由器设置

PacketTracer-配置初始路由器设置目标第1部分:验证默认路由器配置第2部分:配置并验证初始路由器配置第3部分:保存运行配置文件背景信息在本练习中,您将执行基本的路由器配置任务。您需要使用加密密码和明文密码来保护对CLI和控制台端口的访问。还要为登录到该路由器的用户配置消息。这些标语用来警告未授权用户:禁止访问。最后,验证并保存运行配置。说明第1部分:验证默认的路由器配置步骤1:建立与R1的控制台连接。a.  从可用连接中选择Console(控制台)电缆。b.  单击PCA并选择RS232。c.  单击R1并选择Console(控制台)。d.  依次单击PCA>桌面选项卡>终端。e.

Cisco Packet Tracer 三层交换机与两层交换机的配置

使用两台双层交换机(2950)连接一台三层交换机(3560)并连接四台主机1.拓扑网络如下:Pc0连接Sw0fa0/1Pc1连接Sw0fa0/2Pc2连接Sw1fa0/1Pc3连接Sw1fa0/2Sw0fa0/24连接NSwfa0/1Sw1fa0/24连接NSwfa0/22.之后配置一下四台pc的ip地址以及掩码和网卡:      注意:ip地址尾号随意,但是前两位要和网关相对应  3.接下来配置两台双层交换机:   打开CLI命令界面    enable进入特权模式(tab键可自动补全命令)    configureterminal进入全局配置模式    进入vlan配置vlan10
