Coming from a HP Procurve world, we could have 'ip helper-address' settings for each VLAN.  How can I have a production VLAN have a different DHCP server from a Guest VLAN in EXOS?  

Here's my procurve settings:

vlan 200 
  name "VLAN200" 
  ip helper-address 
vlan 500 
  name "VLAN500" 
  ip helper-address 

What would the equivalent of this look like on EXOS?

The article says this as well but you need to make sure you enable bootprelay on the VLAN the server sits on as well. If the discover needs to be routed to get to this VLAN enable bootprelay on the egress VLAN

Hi Bruce, just to add on to what everyone else already said, if you want to send DHCP traffic from one vlan to a specific DHCP server, you can specify the vlan when adding the server in bootprelay. For example:

en bootprelay vlan v1
en bootprelay vlan v2
conf bootprelay vlan v1 add
conf bootprelay vlan v2 add
