Licensing on LTM 2000s

Hello everyone,

I'm doing a quotation of a cluster of 3 LTM 2000s with 2 Power Spply (1 + 1). But I can't find anything about licensing.

I see that now, there are 3 licenses : Good, Better and Best. From this link http://www.f5.com/pdf/licensing/good-better-best-licensing-overview.pdf, I guess the Good license is enouth for me IF the license support a cluster of 3 members.

But what I don't know is, do I need to buy the Good license or is it included in the LTM 2000s when we bought it ?

Thank you, Regards
