【说明】
某园区组网方案如图1-1所示，数据规划如表1-1内容所示。

以Switch3为例配置接入层交换机，补充下列命令片段。
<HUAWEI>( 1 )
[HUAWEI] sysname Switch3
[Switch3] vlan batch( 2 )
[Switch3] interface GigabitEthernet 0/0/3
[Switch3-GigabitEthernet0/0/3] port link-type( 3 )
[Switch3-GigabitEthernet0/0/3] port trunk allow-pass vlan 10 20
[Switch3-GigabitEthernet0/0/3] quit
[Switch3] interface GigabitEthernet 0/0/1
[Switch3-GigabiEthernet0/0/1] port link-type( 4 )
[Switch3-GigabitEthernet0/0/1] port default vlan 10
[Switch3-GigabitEthernet/0/1] quit
[Switch3] stp bpdu-protection

以Switch1为例配置核心层交换机，创建其与接入交换机、备份设备以及出口路由器的互通VLAN,补充下列命令。
<HUAWEI>system-view
[HUAWEI] sysname Switch1
[Switchl] vlan batch( 5 )
[Switch1] interface GigabitEthernet/0/1
[Switchl-GigabitEthernet0/0/1] port link-type trunk
[Switchl-GigabitEthernet0/0/1] port trunk allow-pass( 6 )
[Switch1-GigabitEthernet0/0/1] quit
[Switch1] interface Vlanif 10
[Switch1-Vlanif10] ip address 192.168.10.1 24
[Switch1-Vlanif10] quit
[Switch1] interface Vlanif 20
[Switch1-Vlanif20] ip address 192.168.20.1 24
[Switch1-Vlanif20] quit
[Switchl] interface GigabitEthernet 0/0/7
[Switchl-GigabitEthernet0/0/7] port link-type trunk
[Switch1-GigabitEthernet0/0/7] port trunk allow-pass vlan 100
[Switch1-GigabitEthernet0/0/7] quit
[Switch1] interface Vlanif 100
[Switch1-Vlanif100] ip address( 7 )
[Switch1-Vlanif100] quit
[Switch1] interface Gigabitethernet 0/0/5
[Switch1-GigabitEthernet0/0/5] port link-type access
[Switch1-GigabitEthernet0/0/5] port default vlan 300
[Switchl-GigabitEthernet0/0/5] quit
[Switch1 interface Vlanif 300
[Switchl-Vlanif300] ip address( 8 )
[Switchl-Vlanif300] quit

如果配置静态路由实现网络互通，补充在Switch1和Router上配置的命令片段。
[Switchl] ip route-static( 9 )//默认优先级
[Switchl] ip route-static 0.0.0.0 0.0.0.0 172.16.30.2 preference 70
[Router] ip route-static( 10 )//默认优先级
[Router] ip route-static 192.168.10.0 255.255.255.0 172.16.10.1
[Router] ip route-static 192.168.10.0 255.255.255.0 172.16.20.1 preference70
[Router] ip route-static 192.168.20.0 255.255.255.0 172.16.10.1
[Router] ip route-static 192.168.20.0 255.255.255.0 172.16.20.1 preference70
