DHCP Relay

My question is similiar to the one posted here but the poster did not respond to the suggestions so Im not sure which are correct:

http://www.experts-exchange.com/Hardware/Networking_Hardware/Switches/Q_24265096.html

to qualify the question a bit more:

I have:

 Cisco  2960G switch

And a  Procurve switch wih the following modules:

Card A: HP J4863A 100/1000Base-TX module
Card B HP J4862A 10/100-TX module
Card C HP J4863A 100/1000Base-TX module
Card D HP J4908A 10/100/1000-TX + Mini-GBIC

basically we have been recommended to spliting Data and VoIP networks separate, so for example having data on 192.168.1.x and VoIP on 192.168.2.x

Now I know that both the Cisco and Procurve  do "Ip helper " & "DHCP-relay" but they are both Layer 2 switches (please confirm with the procurve 4104Gl is in fact Layer 2 s Im not sure if the modules add Layer 3 Functionality)

In the link I posted above it seems that there has to be some Layer 3 Functionality for DHCP-Relay to work.  I thought that they just passed on the Frames to the required devices.

Thanks

DHCP Relay should work on your procurve. Yo can check for some information on HP Website:

DHCP relay works on Cisco 2900 too.

Hi,

DHCP relay isn't working on 2960, and ALL L2 devices, it is L3 Feature!

On HP 4104 you need to enable routing, and you need this:

ip routing
vlan 6
   name "DOLGOZOI"
   ip address 10.5.0.254 255.255.0.0
   ip helper-address 172.16.1.2

I should have mentioned that my Procurve is a 4104 Model
 
So why did the point in the link I posted get rewarded to an incorrect answer (if your answer is correct)
This is one of the major bummers of this site tbh

I was thinking of just putting a metric ont the VPN interface that is higher then the point to point interface so should one go down it will fall over to the other one... like 2 default flaoting static routes

Hi,

The floating static route is good, but I advise object  tracking, it is better:

And use HSRP with booth routers, and EIGRP!
