Can I do L3 with SX1018HP switches?

Hi,

I have four SX1018HP switches in two different C7000 chassis from HP. I want to configure MLAG on two switches but the command "ip routing" is not available. The firmware versión is 3.4.0000.

How can I enable that command? Do I need any extra license? If the answer is yes, how can I obtain it?

Thanks in advance.
