Question : Procurve 2910AL network setup question

Greetings,

I'm implementing VOIP into my current network. I have several question for the network setup I should use.

Currently I have about 50 computers. Those 50 computers will now be connected into lan port of my IP phones.

My current gateway is a watchguard Firebox X550E.

The network switches who will manage all this will be two HP Procurve 2910AL 48 GB ports PoE.

Some people told me that my switch should act as my default gateway because we'll be implementing a way much more traffic and it's possible that my Firebox can't handle all this new traffic.



I want to know if those switches can act like a sort of default gateway…I'm not really sure of what it means. I know that this switch can use RIP and have  static IP routing. Those this mean that it can act as my default gateway ?

Also, what should I put into my dhcp server for my default gateway ? my switches or the Firebox ?

Should (or can) I configure DHCP server into the Procurve 2910 ?

I know that I must configure voice and data Vlan.. Does my data Vlan will have the Firebox as a gateway and the voice will have the procurve as the gateway ?

Can you provide me some clear information ?

Thank you

Answer : Procurve 2910AL network setup question

As far as I can see, the proposed gateway-role is just an other way to say that one of the  Procurve 2910's should act as L3-switch and route between the data and voip-vlans.
If so
-the voice-devices in voice-vlan will have the procurve's voice-vlan-IP as the gateway
-the data-devices in data-vlan should have the procurve's data-vlan-IP as the gateway
-the procurve have the Firebox as default gateway.

On the firebox a route-back should be set up so as to reach the vlans via the Procurve.

IP helper address could be set up on the switch with IP routing enabeled , so DHCP could find way between one DHCP-server and clients in more vlans.

Hope you find this clear and helpfull.
