模似分局网络环境：路由器R0为分局光纤接入F0/0路由器地址为218.244.142.5/24                   路由器RO F2/0IP地址为:10.10.10.254/24                  现增加设备有:三层交换机24口R1  48口交换机两台,为提高上网速度,减少原有网络广播负载的产生.调试命令如下:                    R1调试:   R1>enableR1> cisco 输入密码R1> cisco 输入隐藏密码R1>config tR1 config>  典型局域网配置：三层交换机一台，分支交换机三台。假设三层交换机为CORE，分支交换机分别为：BRANCH1，BRANCH2，BRANCH3。分别通过PORT1的光纤模块与核心交换机相连，并且假设VLAN的名称为别为：MANAGE、FINAN、TECH、MAKE、  配置命令步骤： 第一步创建虚拟局域网 CORE#vlan database    进入VLAN配置模式CORE(vlan)#vtp domain CORE  设置VTP管理域名称CORECORE(vlan)#vtp server    设置交换机为服务器工作模式CORE(vlan)#vlan 11 name manage    设置VLAN编号与名称CORE(vlan)#vlan 12 name techCORE(vlan)#vlan 13 name makeCORE(vlan)#exit 第二步封装ISL级连中继协议配置虚拟局域网IP地址 CORE#config tCORE(config)#CORE(config)#interface gigabitEthernet 2/1 配置接口CORE(config-if)#switchport   指定端口工作CORE(config-if)#switchport trunk encapsulation
