基于Boson NetSim 的虚拟局域网和路由协议配置.doc

基于Boson NetSim 的虚拟局域网和路由协议配置姓名：王涛学号：pb07210360实验目的：1、学习交换机上VLAN的配置，验证VLAN的工作原理。2、学习路由器上路由协议的配置，查看路由表的内容。3、完成实验报告，内容包括网络拓扑图，交换机、路由器端口配置，VLAN和路由协议的配置命令、VLAN内容（show vlan）、路由信息（show ip route）、实验室结果等。实验环境：模拟软件Boson NetSim实验内容：一：虚拟局域网的配置。1、用Boson Network Designer绘制拓扑图：2.PC机配置如下，其中相同颜色的主机处于一个部门。PC主机IP地址子网掩码A1192.168.1.1255.255.255.0A2192.168.1.2255.255.255.0A3192.168.1.3255.255.255.0B1192.168.1.4255.255.255.0B2192.168.1.5255.255.255.0表2. 主机IP配置在各自主机上，配置主机的IP地址：a1:IP192.168.1.1mask255.255.255.0a2:IP192.168.1.2mask255.255.255.0a3:IP192.168.1.3mask255.255.255.0b1:IP192.168.1.4mask255.255.255.0b2:IP192.168.1.5mask255.255.255.0pc设置完后可以用ipconfig 来查看主机状态（如图1），（注：图3只显示a1的，其余主机情况类似）图1以上设置用到的代码为：主机：ipconfig /ip ip_addr net_mask 对主机ip地址和掩码进行设置。Ping 192.168.1.*【问题1】：每台主机相互ping，查看哪些主机可以连通，哪些不可以？为什么？答：都可以连通，因为由于现在局域网还没设定所有主机可以由交换机相连。交换机：Sw1: SwitchenSwitch#vlan database Switch(vlan)#vlan 2 name dept1VLAN 2 added: Name:dept1Switch(vlan)#endSwitch#congSwitch#configure terminal Enter configuration commands, one per line.
