Have you run all these commands? Configure Single Area OSPF Globally console(config)#ip routing console(config)#router ospf console(config-router)#router-id 172.16.102.1 console(config-router)#enable  Configuring OSPF on VLANs – Latest Firmware console(config)#interface vlan 201 console(config-if-vlan201)#ip address 172.16.201.2 /24 console(config-if-vlan201)#routing  console(config-if-vlan201)#ip ospf area 0 console(config-if-vlan201)#exit console(config)#interface vlan 202 console(config-if-vlan202)#ip address 172.16.202.1 /24 console(config-if-vlan202)#routing  console(config-if-vlan202)#ip ospf area 0 console(config-if-vlan202)#end  The configuration can be slightly different depending on what firmware and switch you have.  The above commands are for the latest firmware.  Also something to consider is whether you have spanning tree set up correctly.  Use the show spanning-tree active command to verify that the links are in a forwarding state. Ports in any other state will not forward traffic, including routing protocols. Hope this helps, Keep us updated if you can,
