OSPF design case

You are a new hire at ESU (Enormous State University) and are in
the IT organization as a so-called Network Engineer.

Assume EnormousStateUniversity has three different organizations
that overlap at a so-called DeMilitarizedZone with three routers,
each router belongs to a different organization.

Router Abe:  owned by the WAN telco pipe provider.  We call
	them ETCINC (enormous telco inc).

Router Barney:  owned by the School of Engineering

Router Charlie:  owned by the ESU IT organization (they take
	care of the rest of the school that is not the engineering school).

IP address setup:  The entire school has a class B address  179.1.0.0,
and the school of engineering uses 179.1.208.0/20 slice of that
address space (16 Cs).  The IT side has the rest of the address space.

Picture:
		|  high-speed WAN circuit
	    ---------
            | Abe   |        
	    ---------
	        |  100mbit ethernet
	    -------------------- 
	    | dmz ether switch |		DMZ area with 3 routers,
	    --------------------		&& 1 cisco switch
	    | Barney		| Charlie
	---------	  ---------------
	| Barney|         | Charlie     |
        ---------         ---------------
            | to engineering         | to rest of school
	more routers ...       even more routers ...

Note there is only ONE link between Barney/Charlie/Abe and the switch.
Note also that there may be an arbitrary number of routers inside Barney
and Charlie's routing areas.  Abe runs a routing protocol to the 
outside world, but you don't know what it is and don't care 
(not your problem).  You however do care about how Abe works vis-a-vis 
Barney and Charlie.

Initial routing setup:

You discover that OSPF is being used between the three routers.  
E.g., Abe speaks OSPF to Barney and Charlie, and vice-versa.  

OSPF/routing setup:

1. describe how you think OSPF should be setup and why?
Describe the per router setup.

2. or do you think something else entirely should be done?

Note: your solution must include the IP addresses needed for
the IT side and the School of Engineering side.
