VLAN Routing using a 6248 as the Core
We have 1 6248P and 1 3548P behind it. Currently 1 Flat LAN with the Address of 10.10.1.0/24. We are installing a Mitel VoIP system and want a seperate VLAN for the Voice. I have chosen Address 10.10.8.0/24 to be the Voice LAN with VLAN ID of 22. So this leaves us with the Data VLAN of 10.10.1.0/24 VID 1 and the Voice is 10.10.8.0/24 VID22. I want the 6248 to provide the Routing BETWEEN VLAN 1 and VLAN 22 and for any Address that do NOT belong to either VLAN, send them to the Router Interface of the Router on VLAN 1 (Route of Last Resort which is 10.10.1.254). Please either describe ho to accomplish this within the 6248 OR provide a link to the appropriate whitepaper, FAQ oe set of instructions, Please. All help is GREATLY APPRECIATED!

62x series:
conf
ip routing
interface vlan xxx
routing
ip address {if you want an address there}

If you use a routing protocol between between your router and the L3 this should be all that you need if not you will need to configure a gateway of last resort.
ip route 0.0.0.0 0.0.0.0.
You will need to put each port into the VLAN that you want it associated with.
int eth 1/g1
switchport access vlan 8
int eth 1/g2
switchport access vlan 10
.......
The uplink port to the other which you will need to put into TRUNK mode.
interface ethernet 1/g24
description 'Uplink 2548P'
switchport mode trunk
switchport trunk allowed vlan add 8
switchport trunk allowed vlan add 10
Note what VLAN 1 will no longer be available so whatever the IP of the switch is should be your LAN IP for VLAN 10. This IP address should be the default IP for all your client machines.
3548P
configure
interface ethernet
switchport mode trunk
exit
vlan database
vlan 8
vlan 10
exit
interface ethernet
switchport trunk allowed vlan add 8
exit
interface ethernet
switchport trunk allowed vlan add 10
exit
interface vlan 8
ip address 10.10.8.X 255.255.255.0
exit
ip default-gateway 10.10.8.1 (this is the IP address you configured above)
Again same thing you need to put the ports into specific VLAN.
Last thing to note is that if you want to have a phone plugged in and have a computer on the same port via the phone you will need to make the VoIP VLAN tagged and each port would need to be a TRUNK port.
