Can I use two ip helper-address sentences in the same vlan?
interface Vlan27
ip address 10.112.104.10 255.255.255.0
ip helper-address 10.112.127.40
ip helper-address 10.112.98.95
How should I configure DHCP Servers (Windows Server)
Is it correct to split the network? For example 10.112.104.0 /24 into two scopes 10.112.104.0 /25 and 10.112.104.128 /25, one on each server.
The interface vlan will send the DHCP request to both servers? Who will respond first?
I hope you had experience on this.
Thank you in advance
Best Regards!

Hi,
For Windows DHCP servers read this doc

That's one way to configure it. DHCP is cluster-enabled in Windows Server 2008R2.

yes.
> Who will respond first?
Without any additional configuration on the server; the one that processes the request first. But that can be configured as shown in Alex's link.
