but i m using internal router and i just want to do only intervlan routing and it can be performed by using layer 3 switch.

and i want to know that by default which encapsulation method is used ,

and which command is used to verify the encapsulation used.

dot1q is used when a switch interface is configured as a trunk. You have not told us that any switch port is configured as a trunk, and in what you have told us I do not see any requirement for trunking. You can certainly do inter vlan routing on the layer 3 switch without doing trunking.
