Step 4. Modify DHCP service configuration

#vi /etc/dhcp/dhcpd.conf                                                                        

default-lease-time 14400;
max-lease-time 86400;
ddns-update-style none;
subnet 192.168.10.0 netmask 255.255.255.0 {
  option broadcast-address 192.168.10.255;
  option routers 192.168.10.1;
  range 192.168.10.2 192.168.10.253;
  next-server 192.168.10.1;
  if substring (option vendor-class-identifier, 15, 5) = "00007" {
    filename "/BOOTX64.efi";
  }
  else  {
    filename "/pxelinux.0";
  }
}

#vi /etc/dhcp/dhcpd6.conf                                                                      

allow booting;
allow bootp;
ddns-update-style none;
default-lease-time 2592000;
preferred-lifetime 604800;
option dhcp-renewal-time 3600;
option dhcp-rebinding-time 7200;
option dhcp6.bootfile-url code 59 = string;
allow leasequery;
option dhcp6.info-refresh-time 21600;
subnet6 2001::/112 {
        range6 2001::1001 2001::fffe;
        option dhcp6.bootfile-url "tftp://[2001::1]/bootx64.efi";
}

#service dhcpd start                                                                              
#service dhcpd6 start
