Hi,



I am segmenting my network in several vlans for security a bandwidth
reason.



How do I go about using the same DHCP server for all the vlans? Someone
told me that I have to enable DHCP relay, I know how to do that in the
switches but I don't know how to configure the dhcp server to offer the
right IP address depending on the VLAN.



Thanks in advance.



Ramon

All you need is to enable the IP helpers on your routers, so that they
forward the DHCP requests to the DHCP server. The DHCP server has
built-in intelligence to look at the forwarded packet and serve IP
addresses out of the proper scope. It can figure out the scope to use
from the address of the router that forwarded the packet to it, no other
setting is needed on the DHCP server other than creating the scopes and
setting them up with the proper options.

The DHCP server will know what to do as long as you have the scopes setup...

Just add an IP helper address to each of your Vlans in the router to point to your DHCP server

Another method I've seen if you dont particularly want to enable iphelper
across disparate links is the ability to create virtual interfaces (Broadcom
NICs as far I know do this), and just trunk your DHCP ports to have multiple
VLANs.. not saying this is good or bad, but I have seen it.

As others have mentioned: As long as your scopes are setup, there isn't much
to do on the DHCP server side.

You don't need multiple nics as the DHCP DISCOVER packet will have the
necessary IP information int he packet and if the scope for that IP range is
defined, you're good.

The benefit to IPHelpers is that you can achieve a certain degree of
resilience by having two helpers pointing to different DHCP servers,
each with part of the subnet as a scope.

That depends on all the subnets being in the same location usually. If you're centrally delivering DHCP to the branch office then this won't work. :)

Absolutely Brian.

Hopefully your remote side routers will support IP helpers. I use
Netscreen's remotely and they have a convenient option for me to add
DHCP-relay -- nice and neat.

Too complicated in my opinion. The IP helpers work great, and the
functionality is blessed by the RFC's. They work well for all
environments- local as well as remote subnets.



BTW: The same setup is also needed to support PXE clients if they are on
a subnet other than the PXE server. The IP helpers in this case would
include the PXE server as well. If the PXE server is different from the
DHCP server, the IP helpers would have the DHCP as well as the PXE
server in the list.

Huge mess to say the least. Higher ed loves the whole campus VLAN thing in particular - I hate it.

This might work with half a dozen sites or something, but, what if you had 100 or 500 or 1000 branches. Would you span all those VLANs back to a central datacenter? Would you want that many subinterfaces on a DHCP server?

Subject: [ActiveDir] DHCP RELAY?



Hi,



I am segmenting my network in several vlans for security a bandwidth reason.




How do I go about using the same DHCP server for all the vlans? Someone told
me that I have to enable DHCP relay, I know how to do that in the switches
but I don't know how to configure the dhcp server to offer the right IP
address depending on the VLAN.



Thanks in advance.



Ramon
