linux中dhcp如何配置两个子网,linux – 配置DHCP服务器以在同一VLAN上为多个子网提供服务...

我有一个由多个子网组成的VLAN,我想使用DHCP集中IP地址指定.

DHCP服务器(100.100.25.88)是子网100.100.25.64/27上的Debian计算机.我想为子网100.100.68.0/24中的计算机分配IP地址.最终目标是在100.100.68.0/24子网中的所有计算机上启用PXE引导.

下面是我的dhcpd.conf文件,

# DHCP Configuration file

use-host-decl-names on;

ddns-update-style interim;

ignore client-updates;

next-server 100.100.25.88;

# Subnet of DHCP server

subnet 100.100.25.64 netmask 255.255.255.224 {

option subnet-mask 255.255.255.224;

range dynamic-bootp 100.100.25.66 100.100.25.94;

default-lease-time 21600;

max-lease-time 43200;

option domain-name-servers 100.100.25.69, 100.100.44.21;

option routers 100.100.25.65;

filename "pxelinux.0";

}

# Subnet of client machines

subnet 100.100.68.0 netmask 255.255.255.0 {

range dynamic-bootp 100.100.68.10 100.100.68.200;

option subnet-mask 255.255.255.0;

default-lease-time 21600;

max-lease-time 43200;

option domain-name-servers 100.100.25.69, 100.100.44.21;

option routers 100.100.68.1;

option broadcast-address 100.100.68.255;

filename "pxelinux.0";

allow unknown-clients;

}

我理解DHCP的方式,DHCP服务器应该将数据包广播到为第二个子网100.100.68.255指定的广播地址.但是,没有客户端能够检索IP地址.这是我的DHCP配置中的错误,还是因为路由器不启用DHCP中继？

谢谢！
