Yes.  I doubt that quagga supports this; Cisco might.  In practice, 
these two networks would be like ships-in-the-night from the perspective 
of OSPF.  There would be two network LSAs originated; one for the 
10.1.2.0 network and another for the 10.1.1.0 network.  The interfaces 
on 10.1.2.0 would ignore hellos from the 10.1.1.0 interface, and vice versa.

However, in our code, we should probably check that everyone on the same 
link belongs to the same network, since we do not have a Hello process 
to enforce that for us.
