On pp110 of Ch5 the fifth paragraph of Solution 1 suggests that OSPF running on an interface facing the DMZ (bcast network) running another protocol (EIGRP,IS-IS, etc.) could advertise all of the networks on the DMZ as internal routes. My question is how is this done? If this router has no adjacencies on the DMZ then how is anything discovered and propagated into OSPF at all?
I have this problem too.
