组网实验记录

要求:ospf  单臂路由  三层交换  telnet  vlan  接口模式
1.配置设备中所有设备的IP地址
2.配置单臂路由--lsw8为纯二层设备、为保证vlan20、vlan30之间能够互通，需要R1上做单臂路由，子接口g0/0/1.20地址为192.168.20.254/24；子接口g0/0/1.30地址为192.168.30.254/24
实现pc2,pc3之间的通信。
3.全网配置OSPF---如图所示R1、R2、R3、LSW6间运行ospf协议
4.配置三层交换---lsw6为三层设备，通过vlan间路由保证vlan80、vlan90互通
5.r3为telnet服务器，r1能够通过VTY aaa的认证方式登录到r3上
6.保证所有pc之间互通
