Actually, the airsdie bus skips 2D (and 2F1) becuase they are Schengen terminals. You will have to walk to or from 2D. The other terminals are connected by airside bus which keeps you form having to go through passport control (which is helpful for those not possessing a visa for France/the Schengen states but wanting to connect).
