try this example
ip routing # enable your ip routing
create new vlans 2 - 10.
vlan 2
vlan 3
.........
and so forth.
then...
create SVI i used
interface Vlan2
ip address 10.2.0.1 255.255.0.0
interface Vlan3
ip address 10.3.0.1 255.255.0.0
... and so forth
and important your default route
ip route 0.0.0.0 0.0.0.0 10.0.0.137

Hi ,
Try this:
ip routing
!
interface FastEthernet....
switchport access vlan 10
switchport mode access
!
interface FastEthernet.....
switchport access vlan 20
switchport mode access
interface Vlan10
ip address 192.168.10.1 255.255.255.0
!
interface Vlan20
ip address 192.168.20.1 255.255.255.0
*****Note:
And on hosts just assign IP addresses and default gateways (to the corresponding interface VLANs) -> hosts in different VLANs can communicate.
Regards
Please rate if it helps.

There have been several responses that describe enabling routing and configuring routing which enables the hosts on the VLANs to communicate with each other. One response included configuring a default route which would be very important in access to Internet. But so far no one has discussed the need to do address translation. If you are using private addressing on the VLANs then you need to do address translation so the inside hosts can access the public Internet. Unfortunately I do not believe that the 3750 does address translation. So you probably need to connect the 3750 to a router to enable Internet access.
