[AusNOG] DHCP/PXE Packets between multiple VLAN on Vyatta

[Robert Hudson]

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.

Your DHCP server should then give the IP address of the PXE server as a
scope option.

Now you just need to find the command on the vyatta (assuming it can do
it).  Is this helpful?
