本文描述了使用ENsp模拟DHCP Global和DHCP 中继两种简单配置过程。

在这里插入图片描述

DHCP全局配置

此配置较为简单，因为全局既支持局域网，也支持跨网络分配。

# DHCP Server1

[server1]dhcp enable 												# 启用DHCP 服务
[server1]ip pool dhcp_pool											# 创建地址池

DHCP 中继

中继的意思就是要跨网络了，如果使用三层交换机就要划分vlan，比较麻烦。依旧在DHCP Server2创建地址池，通过10.0.0.1端口下发地址。DHCP 中继要能够ping同10.0.0.1，从而获取DHCP配置的地址池，给指定端口下发地址。

# DHCP Server2 同DHCP Server1配置一样
