Inter-vlan routing

i create 3 vlan?s ( vlan2, vlan3, vlan 4) in 2 catalyst 3550( one is server and other is client) and assign a range of ports. I use the same network id: 192.168.33.0 and already made trunking between the switches. The pc?s in the same vlan can connect with each other.

My question is, how to configure inter-vlan routing to make vlan 2 communicating with vlan 3?

thanks
