Dual DHCP helpers on switches

Hiya,

 

Our network department is using Netgear switches of some type and they have dhcp helpers for each VLAN.

 

I am setting up 2 DHCP(NLB\Failover) servers in the environment on Windows 2012R2, is it possible to point the DHCP helper on the switches, to both DHCP servers incase one goes down?

 

cheers Mike

Hi mike1971wright,

Netgear Switch support config more than one DHCP L3 Relay Server IP address.

In your scenario, if you config two DHCP helper IP address, when Switch receive client DHCP Discover packet, it will forwarding packet to both two Servers, and when Switch receive two DHCP Server response packet, it will forwarding to client, and let client to select which Server.

 

 

Hope it can helps!
