2.2 配置服务器数据包到 10.10.10.0/24 和 20.20.20.0/24 网段的路由
#route add -net 10.10.10.0 netmask 255.255.255.0 dev ens37
#route add -net 20.20.20.0 netmask 255.255.255.0 dev ens37
三、检查错误
3.1 tail /var/log/messages #查看错误日志信息
3.2 cat /var/lib/dhcpd/dhcpd.leases #查看DHCP服务器地址分配情况
四、实验结果
PC_1获取到的IP地址如下：
PC_2获取的是一个固定的IP地址20.20.20.20/24
实验目的达到了，over~
