If u create L3 VLANs with separate subnet assigned to each VLAN, u can restrict communication by applying ACLs to each L3 VLAn .

Can you let me know the steps how to restrict communication between VLANS.

We want oto use OSPF as the routing protocol, so what config is required for this..

You can try this:

config t

int vlan 10

description Admin VLAN

ip address

int vlan 20

description Finance VLAN

ip address

int vlan 30

description Server VLAN

ip address

int vlan 40

description User VLAN

ip address

int vlan 50

description Management VLAN

ip address

In the switchports of the 4506, use:

int fa0/1 (whatever port)

description Server Only

switchport mode access

switchport access vlan 20

switchport access vlan 30

int fa0/2

description Management

switchport mode access

switchport access vlan 10

switchport access vlan 50

inf fa0/3

description Other VLANS

switchport mode access

switchport access vlan 40

Make sure that you assign workstations/servers to the right switchport, and check IP ROUTE is correct.
