Catalyst 6500 Inter-VLAN Routing

I have a Cisco 6500 switch and I have a question about inter-vlan routing and the "IP ROUTING" command.  I use switched virtual interfaces (I.e. int vlan 2, int vlan 3, etc.) but I noticed I do not have IP ROUTING enabled on my switch but I am able to route between VLANs just fine.  I even have some of the ports that I configured with "no switchport" command and I've assigned those ports an IP address.  On these routed ports, there's another switch on the other side configured with an IP address and I'm able to ping and route traffic to that other network.

I've done some research on this and all the documentation I'm able to find talks about how you need to enable IP ROUTING in order to route between VLANs.  I'm assuming this only needs to be done if you're going to route to other networks not directly connected.

Can somebody clarify this for me?

For the 6500 series, IP routing is enabled by default therefore all vlans can communicate with each other.  You don't need to turn it on like you do for other switches (ie 3560, 3750, 3850, etc..)
