Ok.

I agree. However, in a scenario where nodes are *mobile* and have 
(multiple) *point to point radio* devices (with directional antennas) 
for communication between them, is it possible for the following to occur?

(Note: I don't have much idea about the radio devices).

|eth1: 10.2.1.1/16|<------>|eth0: 10.1.1.2/16|
+-----------------+        +-----------------+

If yes, are there any workarounds? Thank you.
