一、实验拓扑图：

二、设置PC IP

三、设置路由器SW1

[SW1]vlan 10		【创建vlan10】
[SW1-vlan10]vlan 20	【创建vlan20】
[SW1-vlan20]exit
[SW1]interface g 1/0/2
[SW1-GigabitEthernet1/0/2]port access vlan 10	【端口接入vlan10】（是两条名的缩写）（接口默认就是接入）
[SW1-GigabitEthernet1/0/2]quit
[SW1]interface g 1/0/1
[SW1-GigabitEthernet1/0/1]port access vlan 20	【端口接入vlan20】
[SW1-GigabitEthernet1/0/1]quit
[SW1]%May  9 15:17:51:687 2025 SW1 LLDP/5/LLDP_PVID_INCONSISTENT: PVID mismatch discovered on GigabitEthernet1/0/3 (PVID 1), with SW2 GigabitEthernet1/0/1 (PVID 20).

%May  9 15:18:22:709 2025 SW1 LLDP/5/LLDP_PVID_INCONSISTENT: PVID mismatch discovered on GigabitEthernet1/0/3 (PVID 1), with SW2 GigabitEthernet1/0/1 (PVID 20).

%May  9 15:18:53:388 2025 SW1 LLDP/5/LLDP_PVID_INCONSISTENT: PVID mismatch discovered on GigabitEthernet1/0/3 (PVID 1), with SW2 GigabitEthernet1/0/1 (PVID 20).


[SW1]interface g 1/0/3
[SW1-GigabitEthernet1/0/3]port link-type trunk
[SW1-GigabitEthernet1/0/3]port trunk permit vlan 10 20
[SW1-GigabitEthernet1/0/3]quit
[SW1]

四、设置路由器2 SW2

[H3C]sysname SW2
[SW2]vlan 10
[SW2-vlan10]vlan 20
[SW2-vlan20]quit
[SW2]interface g 1/0/2
[SW2-GigabitEthernet1/0/2]port access vlan 10
[SW2-GigabitEthernet1/0/2]quit
[SW2]interface g 1/0/1
[SW2-GigabitEthernet1/0/1]port access vlan 20
[SW2-GigabitEthernet1/0/1]quit
[SW2]%May  9 15:17:24:817 2025 SW2 LLDP/5/LLDP_PVID_INCONSISTENT: PVID mismatch discovered on GigabitEthernet1/0/1 (PVID 20), with SW1 GigabitEthernet1/0/3 (PVID 1).


[SW2]undo%May  9 15:17:53:821 2025 SW2 LLDP/5/LLDP_PVID_INCONSISTENT: PVID mismatch discovered on GigabitEthernet1/0/1 (PVID 20), with SW1 GigabitEthernet1/0/3 (PVID 1).
[SW2]undo info-center enable
Information center is disabled.
[SW2]interface g 1/0/1
[SW2-GigabitEthernet1/0/1]undo port access vlan
[SW2-GigabitEthernet1/0/1]quit
[SW2]interface g 1/0/3
[SW2-GigabitEthernet1/0/3]port access vlan 20
[SW2-GigabitEthernet1/0/3]quit
[SW2]interface g 1/0/1
[SW2-GigabitEthernet1/0/1]port link-type trunk
[SW2-GigabitEthernet1/0/1]port trunk permit vlan 10 20
[SW2-GigabitEthernet1/0/1]quit

五、PC1下ping PC2\PC3\PC4
