HP Procurve 2910al VOIP & Data VLANs

[tluimes]

I'm currently configuring a 3 switch stack. Commander: 2910al, Member1: 2910al, Member2: 2910al+POE.
I have 2 VLANs, VLAN 1 for Data, VLAN 10 for voice.
VLAN 1 is on subnet 10.100.200.0/24 and VLAN 10 is on subnet 10.100.205.0/24. Right now I'm having trouble getting my two subnets to communicate. The devices can sommunicate accross switches when connected to the same network.


Here's my config.
switch 1----------------------------------
default-gateway 10.100.200.1
ip routing
vlan 1
name "DEFAULT_VLAN"
untagged 1-48
ip address 10.100.200.110 255.255.255.0
ip proxy-arp
exit
vlan 10
name "VOIP1"
tagged 1,37,47
ip proxy-arp
exit
spanning-tree
spanning-tree priority 1

switch2------------------------------------------------
default-gateway 10.100.200.1
vlan 1
name "DEFAULT_VLAN"
untagged 1-48
ip address 10.100.200.111 255.255.255.0
exit

vlan 10
name "VOIP1"
tagged 1,38,43,47
no ip address
exit

switch3------------------------------------------------
defualt-gateway 10.100.200.1
vlan 1
name "DEFAULT_VLAN"
untagged 1-48
ip address 10.100.200.112 255.255.255.0
exit

vlan 10
name "VOIP1"
tagged 1-48
no ip address
exit

VLAN1:
Change the GW address for the VLAN1 clients to the ip addr from SW1, Make sure you have VLAN routing enabled, and you have a route 0.0.0.0/0.0.0.0/X.X.X.X Where X.X.X.X is you internet GW.

VLAN10:
Change the GW address for the VLAN10 Phones to the Interface addr from SW1 VLAN10 (Make sure the interface has an IP addr).

If you do not wan't to change the GW addr on the clients, then you need to do a route add in a CMD prompt.

route add X.X.X.0 MASK 255.255.255.0 Y.Y.Y.Y

So X.X.X.0 is you network on the next VLAN10 and Y.Y.Y.Y is your routing SW1.

It works! Now if only I could remember what I did...

The basic problem here is that Switch 1 has no IP address in VLAN10.
To route between two subnets, a switch needs:
1/ IP routing enabled
2/ Physical connection to both networks
3/ An IP address in each subnet (usually an addressed VLAN interface)
