一、实验目标掌握交换机Tag VLAN 的配置;掌握三层交换机基本配置方法;掌握三层交换机VLAN路由的配置方法;通过三层交换机实现VLAN间相互通信;二、实验背景某企业有两个主要部门,技术部和销售部,分处于不同的办公室,为了安全和便于管理,对两个部门的主机进行了VLAN的划分,技术部和销售部分处于不同的VLAN。现由于业务的需求,需要销售部和技术部的主机能够相互访问,获得相应的资源,两个部门的交换机通过一台三层交换机进行了连接。三、技术原理三层交换机具备网络层的功能,实现VLAN间相互访问的原理是:利用三层交换机的路由功能,通过识别数据包的IP地址,查找路由表进行选路转发。三层交换机利用直连路由可以实现不同VLAN之间的互相访问。三层交换机给接口配置IP地址,采用SVI(交换虚拟接口)的方式实现VLAN间互连。SVI是指为交换机中的VLAN创建虚拟接口,并且配置IP地址。四、实验步骤实验拓扑1、在二层交换机上配置VLAN 2、VLAN 3,分别将端口2、端口3划到VLAN 2、VLAN 3;2、将二层交换机与三层交换机相连的端口Fa0/1定义为Tag VLAN模式;Switch>en Switch#conf t Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#vlan 2 Switch(config-vlan)#exit Switch(config)#vlan 3 Switch(config-vlan)#exit Switch(config)#interface fa0/2 Switch(config-if)#switchport access vlan 2 Switch(config-if)#exit Switch(config)#interface fa0/3 Switch(config-if)#switchport access vlan 3 Switch(config-if)#exit Switch(config)#interface fa0/1 Switch(config-if)#switchport mode trunk %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to down %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up Switch(config-if)#3、在三层交换机上配置VLAN 2、VLAN 3,分别将端口2、端口3划到VLAN 2、VLAN 3;
Switch>en Switch#conf t Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#vlan 2 Switch(config-vlan)#exit Switch(config)#vlan 3 Switch(config-vlan)#exit Switch(config)#interface fa0/2 Switch(config-if)#switchport access vlan 2 Switch(config-if)#exit Switch(config)#interface fa0/3 Switch(config-if)#switchport access vlan 3 Switch(config-if)#exit Switch(config)#4、设置三层交换机VLAN间通信,创建VLAN 2、VLAN 3的虚拟接口,并配置虚拟接口VLAN 2、VLAN 3的IP地址;
Switch(config)#interface vlan 2 //创建 VLAN 2 的虚拟接口 Switch(config-if)# %LINK-5-CHANGED: Interface Vlan2, changed state to up %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan2, changed state to up Switch(config-if)#ip address 192.168.1.1 255.255.255.0 //配置虚拟接口 VLAN 2 的IP地址 Switch(config-if)#no shutdown Switch(config-if)#exit Switch(config)#interface vlan 3 //创建 VLAN 2 的虚拟接口 Switch(config-if)# %LINK-5-CHANGED: Interface Vlan3, changed state to up %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan3, changed state to up
Switch(config)#interface vlan 3
Switch(config-if)#ip address 192.168.2.1 255.255.255.0 //配置虚拟接口 VLAN 2 的IP地址 Switch(config-if)#no shutdown
Switch(config-if)#exitSwitch(config)#ip routing // 开启路由交换Switch(config-if)#endSwitch#5、查看三层交换机路由表
Switch#show ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area * - candidate default, U - per-user static route, o - ODR P - periodic downloaded static route Gateway of last resort is not set C 192.168.1.0/24 is directly connected, Vlan2 C 192.168.2.0/24 is directly connected, Vlan3 Switch#6、将VLAN 2、VLAN 3下的主机默认网关分别设置为相应虚拟接口的IP地址;五、验证打开PC1 Command Prompt
