Hi
Your question seems abstract. Well, if you just want to have inter-vlan routing among those 3 vlans than you have and just to have config, then you could follow the following commands.
interface vlan 1
ip address X.X.X.X X.X.X.X
no shut
interface vlan 2
ip address X.X.X.X X.X.X.X
no shut
interface vlan 3
ip address X.X.X.X X.X.X.X
no shut
If you want to configure HSRP then you should have few more command to configure.
