某园区组网方案如图1-1所示，数据规划如表1-1所示。

［问题1］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] interfaceGigabitEthernet 0/0/3
[Switch3-GigabitEthernet0/0/3] port link-type (3) 
[Switch3-GigabitEthernet0/0/3] port trunk allow-pass vlan 1020
[Switch3-GigabitEthernet0/0/3] quit 
[Switch3] interface GigabitEthernet 0/0/1
[Switch3-GigabitEthernet0/0/1] port link-type (4) 
[Switch3-GigabitEthernet0/0/1] port default vlan 10
[Switch3-GigabitEthernet0/0/1] quit
[Switch3] stp bpdu-protection

［问题2］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 
[Switch1] vlan batch(5)
[Switch1] interface GigabitEthernet0/0/1
[Switch1-GigabitEthernet0/0/1]port link-type trunk
[Switch1-GigabitEthernet0/0/1]port trunk allow-pass (6)
[Switch1-GigabitEthernet0/0/1]quit
[Switch1]interface Vlanif 10 
[Switch1-Vlanif10] ip address192.168.10.1 24
[Switch1-Vlanif10] quit
[Switch1]interface Vlanif 20
[Switch1-Vlanif20] ip address 192.168.20.1 24
[Switch1-Vlanif20] quit
[Switch1] interfaceGigabitEthernet 0/0/7
[Switch1-GigabitEthernet0/0/7] port link-type trunk
[Switch1-GigabitEthernet0/0/7] port trunk allow-pass vlan 100
[Switch1-GigabitEthernet0/0/7] quit
[Switch1] interface Vlanif100
[Switch1-Vlanif100] ip address (7)
[Switch1-Vlanif100] quit
[Switch1] interface GigabitEthernet0/0/5
[Switch1-GigabitEthernet0/0/5] port link-typeaccess
[Switch1-GigabitEthernet0/0/5] port defaultvlan 300
[Switch1-GigabitEthernet0/0/5] quit
[Switch1] interface Vlanif 300
[Switch1-Vlanif300] ip address (8)
[Switch1-Vlanif300] quit

［问题3］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。

[Switch1] ip route-static（9）//默认优先级
[Switch1] ip route-static 0.0.0.0 0.0.0.0 172.16.30.2 preference70
[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. 10.0 255.255.255.0172.16.20.1 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
