Not too surprising - ge-0/2/0 is a LAN interface and
we have to know the MAC address of the next hop.  We
can only get this if you specify a gateway address on
the LAN.  Even if there's only one other address on
the link, you still need to specify it's address;  
there just ain't no such thing as a point-to-point
LAN.  :)

The same command works just fine on a P2P link.
