Cisco PT模拟实验(12) 路由器静态路由的配置 实验目的: 掌握静态路由的配置方法和应用 掌握路由选择表中的路由描述 熟悉路由选择和分组转发的原理及过程 实验背景: 某公司除总部外,另有一处分部,并且都有一个独立的局域网,为了使公司各部之间能相互通信,共享资源.每个出口利用一台路由器进行连接,两台路由器间公司申请了一条DDN专线(数字数据网)进行相连,要求做适当配置实现相互访问. 技术原理: 路由器属于网络层设备,能够根据IP数据报的首部信息,选择一条最佳路径(这一过程称为"路由选择&q

配置Cisco 路由器的静态路由

之前我们通过几篇博文方向了路由器的基础信息配置的方法.大家也应该掌握了IT民工所具备的四大技能:开得了设备,接得了线路,设得了地址,ping得了IP.今天咱们来看一下静态路由如何设置,如何让不同地址段的地址互通. 根据拓图扑通所给出的信息,我们为三台路由器的端口配置好IP地址. 配置好端口的IP 地址后,在Yong1上做如下操作, 不成功,原因是路由表中没有到达192.168.2.0网段的信息 什么是路由表,我们可以在路由器上用show ip route 命令来看一下路由表的内容 'C代表的是直

Cisco基础--VLan、静态路由、默认路由综合实验

CISCO CCNA 静态路由

由于网络的需求,大部分网络需要两台路由及两台以上.此时当客户机访问目标网络需跨越多个路由时就需要网络管理员在各路由器上去配置路由协议.而静态路由协议往往配置在网络较小而且不易变动的小规模网络中. 路由就是把信息从源传输到目的地的行为.信息包就可以是看作是一个代,而路由就可以说是一张地图,路由表即为行走的路径.静态路由是管理员手动一条一条的配置,路由器之间不会相互学习路由表.当网络的拓扑结构或链路的状态发生变化时,网络管理员需要手工去修改路由表中相关的静态路由信息.静态路由信息在缺省情况下是私有的

通过思科模拟器CISCO PACKET TRACER学习网络7——静态路由

两个不同区域的网络若想实现通信,需要在路由器上配置路由来实现网络中的终端收发跨本网络的数据包 路由器可以连接多个网络,但是路由器本身并不知道其它网络的信息,这时我们需要手动配置静态路由让路由器知道其他网络信息或者配置动态路由让路由器自己学习其他网络的信息. 本次学习配置静态路由 配置思路 1配置路由器下联交换机的物理接口,开启端口并配置IP地址 2配置PC的IP地址,并设置网关为交换机上联路由器的物理接口地址 3配置路由器之间连接的物理接口,开启端口并配置IP地址 4新建两台路由器的静态路由条目
