基于eNSP的DHCP中继代理的原理分析与应用

Principle Analysis and Application of DHCP Relay Agent Based on eNSP

针对中、大型以太网络中因网络划分而带来的DHCP广播无法到达的问题,文中规划设计了一种基于eNSP的DHCP中继代理的实施方案。首先分析了DHCP服务应用场景及其面临的问题,然后对DHCP中继的实现原理进行了分析,最后在eNSP模拟软件中设计了一个生产生活中常见的网络应用拓扑进行实施应用,测试结果表明,该设计方案完全达到了预期目标。

Aimming at the problem that the DHCP broadcasting can’t reach because of the network division in the medium and large Ethernet,in this paper,an implementation scheme of DHCP relay agent based on eNSP is designed.Firstly,it analyzes the application scenarios of DHCP service and the problems it faces,then analyzes the implementation principle of DHCP relay,and finally designs a common network application topology in production and life by eNSP simulation software for application.The test results show that the design scheme fully achieves the expected goal.
