Thanks. We'll let you know when a new response is added.

Since you haave created 3 virtual ip interface , the networks must be coming in routing taable as directly connected.
Check the ip routing table >>>>>>>>
You can simply disable IP routing and stop inter VLAN communication. >>>>>>

    did you configure the ip interfaces as layer 3 interfaces? did you assign the ip of the interfaces as the default gateway of the clients? are the clients in thesame subnet as the port on the switch to which they are connected? if the answer is yes to these questions, then it does not need any other configuration for the systems to communicate, you dont need any routing configurations on a router to route between directly connected networks because that is exactly what you have.
