2 dhcp on same network

[newbie]

How can I configure network to run 2 DHCPs?

 

[Phillip Windell]

Configure them exactly identical. Then use Exclusions so that one gives out
the first half of the available addresses and the other gives out the second
half of the available addresses. If you use any Reservations then make sure
they are the same on both server.

If one server goes down you can just delete the Exclusion on the remaining
one and it will keep things going until the first one is fixed. In fact if
half the addresses is enought of keep things going then you won't even have
to delete the Exclusion.

Please elaborate:

Are you trying to get a client to get 2 DHCP Addresses? ( Not possible )

or

Are you trying to run 2 different DHCP Servers on the same network? ( just
install a second server with the DHCP service installed and configure to
your needs)

or

Are you trying to issue two different ranges of addresses from your DHCP
server? ( Create a second scope on the DHCP server )

You divide the address scope in two:
e.g.
For a network based on 192.168.1.0 mask 255.255.255.0

DHCP server 1 serves IP adresses 192.168.1.50 to
192.168.1.150

DHCP server 2 serves IP addresses 192.168.1.151 to
192.168.1.254

This scheme keeps IP addresses 192.168.1.1 to 192.168.1.49
for devices using static ip addresses.

You can even get more elaborate using dhcp relay agents
and serving redundant IP address schemes across the WAN

The trick is to divide the DHCP Scope address range and
never let the address range overlap
