实验指导(三层交换)一、 实验任务1. PC1用R1模拟， PC2用R2模拟; PC3用R3模拟， PC4用R4模拟2. 在SW1上实现VLAN2、VLAN3之间的路由。注意VLAN2和VLAN3上的计算机网关设置；3. 在SW2上实现VLAN2、VLAN3之间的路由。注意VLAN2和VLAN3上的计算机网关设置；二、 实验步骤1、 清除交换机的配置（在三台交换机上执行）：Switch#erase startup-configSwitch#delete flash:vlan.datSwitch#reload2、 预配：步骤1：交换机的配置S1:=Vlan 2Vlan 3interface FastEthernet0/13 switchport trunk encapsulation dot1q switchport mode trunkchannel-group 1 mode desirableinterface FastEthernet0/14switchport trunk encapsulation dot1qswitchport mode trunkchannel-group 1 mode desirableinterface FastEthernet0/15shutdowninterface FastEthernet0/1 switchport mode access switchport access vlan 2interface FastEthernet0/2 switchport mode access switchport access vlan 3S2: =interface FastEthernet0/13 switchport trunk encapsulation dot1q switchport mode trunkchannel-group 1 mode desirableinterface FastEthernet0/14switchport trunk encapsulation dot1qswitchport mode trunkchannel-group 1 mode desirableinterface FastEthernet0/15shutdowninterface FastEthernet0/1 switchport mode access switchport access vlan 2interface FastEthernet0/2 switchport mode access switchport access vlan 3步骤2：路由器的配置 R1:no ip routingint f0/0no shutip add 172.16.2.1 255.255.255.0ip default-gateway 172.16.2.252R2:no ip routingint f0/0no shutip add 172.16.3.2 255.255.255.0ip default-gateway 172.16.3.252R3:no ip routingint f0/1no shutip add 172.16.2.3 255.255.255.0ip default-gateway 172.16.2.253R4:no ip routingint f0/1no shutip add 172.16.3.4 255.255.255.0ip default-gateway 172.16.3.2533、 三层交换：SW1:ip routingint vlan2no shutip add 172.16.2.252 255.255.255.0int vlan3no shutip add 172.16.3.252 255.255.255.0SW2:ip routingint vlan2no shutip add 172.16.2.253 255.255.255.0int vlan3no shutip add 172.16.3.253
