ge-0/0/0 is multiaccess interface so if you look at:
run show route forwarding-table destination 2.2.2.0/24
you will see the "rslv" type for this destination(emty next-hop) - that means that any packet matching 2.2.20/24 require additional "resolution" lookup through ARP. In your case nobody will reply to this arp request, so communication is broken(as expected).
