<div dir="ltr">ip helper-address will certainly work for DHCP. You specify the IP address of your DHCP server, and what happens is that the switch listens for DHCP requests and forwards them to the DHCP server on another VLAN, and then ensures that an IP in the correct IP address range for that subnet is returned for the client.<div>

Ive never used it on Cisco before either, However ive been told its one<br>
of these 3<br>
<br>
"ip helper-address", "DHCP relaying” or “Broadcast forwarding”<br>
<br>
Just not entirely sure on which one would apply for Vyatta<br>
