1、一、配置基本的拓扑结构由于配置三层交换通信，R3属于上次实验遗留下的，在本次实验中关闭相应的接口，S1、S2是本次实验配置重点
2、二、配置接口IP地址R1的接口：[R1-GigabitEthernet0/0/1]ip address 10.0.2.2 255.255.255.0R2的接口：[R2-GigabitEthernet0/0/2]ip address 10.0.3.2 255.255.255.0R3的接口：interface GigabitEthernet0/0/1 ip address 10.0.2.1 255.255.255.0 interface GigabitEthernet0/0/2 ip address 10.0.3.1 255.255.255.0
3、三、关闭S1的G0/0/4接口，并验证网络现在状况[S1]interface GigabitEth髫潋啜缅ernet 0/0/4[S1-GigabitEthernet0/0/4]shutdown[R1]ping 10.0.30.2 PING 10.0.30.2: 56 data bytes, press CTRL_C to break Request time out Request time out Request time out Request time out Request time out --- 10.0.30.2 ping statistics --- 5 packet(s) transmitted 0 packet(s) received 100.00% packet loss
4、四、更改S1、S2的G0/0/9端口模式为TRUNK，并运行通过VLAN2、VLAN3[S1]interface GigabitEthernet 0/0/9[S1-GigabitEthernet0/0/9]port default vlan 1[S1-GigabitEthernet0/0/9]port link-type trunk[S1-GigabitEthernet0/0/9]port trunk allow-pass vlan 2 3[S2]interface GigabitEthernet 0/0/9[S2-GigabitEthernet0/0/9]port default vlan 1[S2-GigabitEthernet0/0/9]port link-type trunk[S2-GigabitEthernet0/0/9]port trunk allow-pass vlan 2 3
5、五、在S1上创建VLANif2、VLANif3[S1]interface Vlanif 2[S1-Vlanif2]ip address 10.0.20.1 24[S1]inter Vlanif 3[S1-Vlanif3]ip address 10.0.30.1 24
6、六、测试网络的联通性[R1]ping -c 1 10.0.30.2PING 10.0.30.2: 56 data bytes, press CTRL_C to breakReply from 10.0.30.2: bytes=56 Sequence=1 ttl=254 time=2 ms--- 10.0.30.2 ping statistics ---1 packet(s) transmitted1 packet(s) received0.00% packet lossround-trip min/avg/max = 2/2/2 ms
