Multiple DHCP servers in the same VLAN

I am having one DHCP server feding my LAN, I want to run another DHCP
server
to feed part of this LAN (Servers parts which have static IP addresses)
and i
want these servers to take their IP from the new DHCP (called it the
Blade
DHCP) and these dynamic IP addresses just used for network boot (PXE),
the
question here is how to configure the two DHCP servers without having
loops,
and every group take its ip from the desired DHCP? Take in mind that i
cannot
now isolate the servers in other VLAN for now.

You might want to have a look at the following:

hi dear,

lets say u have 2 DHCP server
and 100 clients
#1(old) 1st 50 clients

#2(new) 2nd 50 clients

the answer of ur question is

put 1st 50 clients in segment or subnet and connect DHCP #1 in this subnet

and put 2nd 50 clients in other subnet and connect DHCP #2 in this subnet

lets say DHCP #1 & 1st 50 CLient configured with Ip range 192.168.1.0 &
subnet mask 255.255.255.0

and DHCP #2 & 2nd 50 client configured ip range 192.168.2.0 & subnet mask
255.255.255.0

if this case u ensure thats each client recieve the ip from the DHCP server
in its subnet or segment

if u want me to help u when u configuer it tell me

Thank you all,
But still the problem. am having let say DHCPA and DHCPB, i want let say 50
client to be fed by DHCPA and the rest by DHCPB. how i can configure the
DHCPA to just be responsible of just the 50 clients. and how i can configure
the 50 clients to just take their IP from DHCPA.
Hello Michael Giorgio: can you contact me on this email so i can contact you
online when i configure it: here is my email (E-Mail Removed).

Dear,

But still the problem exist, I cannot put them in two physical networks. Am
asking for a way to assign my clients to two different DHCP servers, let sat
I have DHCP A and DHCP B. I want 50 clients (Blade servers) to be assigned to
DHCP A and just to it. And I want DHCP A to give IPs just to the 50 clients.
And the other DHCP server (DHCP B) to give IPs to the rest of the clients on
my LAN.

Thank you all,
I am having one DHCP server feding my LAN, I want to run another DHCP
server
to feed part of this LAN (Servers parts which have static IP addresses)
and i
want these servers to take their IP from the new DHCP (called it the

the
question here is how to configure the two DHCP servers without having
loops,
and every group take its ip from the desired DHCP? Take in mind that i
cannot
now isolate the servers in other VLAN for now.

It simply can't be done. That is why I listed two workarounds.
There is no way to force a machine to use a paticular DHCP
server.
