路由交换网络是当前流行的网络架构,DHCP是当前主流的获得IP地址协议。在现有的网络设备上利用DHCP中继技术实现动态IP地址的分配,既节省网络建设成本,又方便统一管理。在真实设备上实验表明:方案运行稳定、效率较高、无需额外的DHCP服务器且易于实现。 Routing switching network is the current popular network architecture, DHCP is the current mainstream access to IP address protocol. In the existing network equipment using DHCP relay technology to achieve dynamic IP address allocation, saving network construction costs, but also facilitate the unified management. Experiments on real devices show that the solution runs stably and efficiently, without additional DHCP server and easy to implement.
