以下是本次作业的各个设置的配置命令，配置流程是先配交换机（VLAN 划分 + Trunk）→ 再配路由器接口 IP → 接着配路由协议（OSPF + 静态路由）→ 最后配 DHCP、NAT、ACL、Telnet 等业务。

其中验证过程DHCP 验证：在 PC 上执行 ipconfig，确认获取对应 VLAN 网段 IP 和网关。
Telnet 验证：在 test 设备上执行 telnet 172.16.66.254，输入密码 123456，确认登录成功
ACL 验证：PC1 ping PC5（不通）、PC3 ping 业务 B 网段（不通），其他设备互通
NAT 验证：在 Client1 上 ping 100.0.0.2，在 R3 上执行 display nat session 查看转换记录。
以上就是本次配置的部分过程
