- S1：需要创建 vlan、配置 access 和 trunk 接口、并将相应接口加入对应 vlan3 中。
- S2：需要创建 vlan、配置 access 和 trunk 接口、并将相应接口加入对应 vlan9 中。
- S3：需要创建 vlan、配置 access 和 trunk 接口、配置 vlanif 3 和 vlanif 9 接口及其 IP 地址，创建 vlan1002，并配置 vlanif 1002 接口及其 IP 地址 192.168.2.1/24。
- S4：需要创建vlan、配置access和trunk接口、配置vlanif 105接口及其IP地址，创建vlan1004，并配置 vlanif 1004 接口及其 IP 地址 192.168.4.1/24。
路由器
