yeah creating and managing vlans is slightly different, so keep that in mind. to configure vlans you have to be in normal enable mode.

Router#vlan database
Router(vlan)#vlan 10 name test_vlan
VLAN 10 added:
Name: test_vlan
Router(vlan)#exit
APPLY completed.
Exiting....
Router#sh vlan-switch

VLAN Name Status Ports

Keep in mind that vlan database mode is deprecated and will be going away at some point, so don't get too comfortable with it

actually i am studying IP multicast and here some configuration of switch is required, so thats why i am using router as a switch in gns3 ?

can we use this router as a switch in bcmsn ?
i will be starting it soon, so would like to know that can we do all configuration required here ? or a seperate switch is required ?

BCMSN tests on layer 3 switching, and GNS3 doesn't emulate switching all that well. You're better off getting your hands on a 3550 and practicing with that.

Yeah I use the vlan command in global config.
