Thanks Brian. I got it now. My misunderstanding. I am actually your student
testing out the compatibility you mentioned in the lab. You said that in
both broadcast and non-broadcast, all OSPF router must have layer 2
connectivity to each other because the DR does not modify the next hop.
I tested it. In the case R2 is the DR and it did modify the route it
received from R4 to R5. Am I missing anything?
R2
O 200.0.0.4 [110/65] via 150.50.24.4, 00:00:25, Serial0/0/0.24
R5
O 200.0.0.4 [110/129] via 150.50.100.2, 00:00:10, Serial0/0/0
