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

二、配置接口IP地址
R1的接口：[R1-GigabitEthernet0/0/1] ip address 10.0.2.2 255.255.255.0
R2的接口：[R2-GigabitEthernet0/0/2]ip address 10.0.3.2 255.255.255.0
R3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

三、关闭S1的G0/0/4接口，并验证网络现在状况
[S1]interface GigabitEthernet 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

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

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

六、测试网络的联通性
[R1]ping -c 1 10.0.30.2
PING 10.0.30.2: 56 data bytes, press CTRL_C to break
Reply from 10.0.30.2: bytes=56 Sequence=1 ttl=254 time=2 ms
--- 10.0.30.2 ping statistics ---
1 packet(s) transmitted
1 packet(s) received
0.00% packet loss
round-trip min/avg/max = 2/2/2 ms
