篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了思科模拟器做dhcp,一台pc,一台路由器做中继,一台路由器做服务器,求配置命令相关的知识,希望对你有一定的参考价值。

额,图颠倒了

参考技术A R0配置:
ip dhcp pool 2
network 192.168.2.0 255.255.255.0
default-router 192.168.2.2
dns-server 8.8.8.8

interface FastEthernet0/0
ip address 192.168.1.1 255.255.255.0
no shutdown

ip route 192.168.2.0 255.255.255.0 192.168.1.2

R1配置:
interface FastEthernet0/0
ip address 192.168.1.2 255.255.255.0
no shutdown

interface FastEthernet0/1
ip address 192.168.2.2 255.255.255.0
no shutdown
ip helper-address 192.168.1.1本回答被提问者采纳
参考技术B 我个人认为脑残不宜提问

实操 :华为DHCP中继服务配置

前言:

该实验是华为模拟器eNSP模拟器、dhcp中继实验
#DHCP中继的应用场景:
通常在DHCP分配网段过多的情况下,网关路由器上配置DHCP服务,压力过大,
一般我们用第二路由器,或则第二台DHCP服务器来分担业务

dhcp 中继

这里设置一台专用的DHCP服务器为pc机配置IP地址
