Re: Dhcp

Yes, for the same network with different ip ranges served by each one. This would provide High availability.

Example:

DHCP1 range 192.168.10.1-100
DHCP2 range 192.168.10.101-200
Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?

Re: Dhcp

Hi,

U can use two DHCP server in different network for different IP block

example,
DHCP1: 192.168.0.0----192.168.0.254
DHCP2:192.168.1.1----192.168.1.254

Re: Dhcp

"You can have multiple DHCP servers on your network as long as their subnet pools do not overlap. However, it is recommended that you have only one DHCP server for your entire network. "

http://docs.hp.com/en/B2355-90685/ch06s02.html

it is used for fault tolerance:

"Multiple DHCP servers cannot serve addresses from the same scope. If you do configure two DHCP servers with the same scope, it wonâ t be long before duplicate IP addresses start to appear on the network. The solution is simply to distribute the range of available addresses across the DHCP servers."
