Depends on what you have.
Do you have a Layer 3 switch or a router?
If you will use the router for the inter vlan routing than its named as router on a stick, while if you used a Layer three switch than its called Layer 3 switch-Inter VLAN Routing
Hope it will help
Tnx i get my answer!!!
one question i have. What is the other methods of inter vlan routing except with router and mls!!?

The last method is to configure each router port ( as a layer 3 port) connecting to each switch port as an access port.
this is the less scalable method of the 3.
If you do not have any other question, please mark the question as answered,
Its really depends how you want to configure inter vlan routing and what you want to use.
Please check this link and its explaining all the different methods you can use.
