Have you run all these commands?

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,
