You are on the right track.
Router 3 does need to be the DR but router's 4 and 5 need to
NOT be a BDR. Also you will need neighbor statements. You
can put the priority on the neighbor statement.
So router 1 has a priority of say 90 and routers 4 and 5 have
a priority of 0 to keep them from ever becomming a BDR or DR.
router ospf 9
neighbor 133.9.4.4 priority 0
neighbor 133.9.5.5 priority 0
do the same on routers 4 and 5 with neighbor statements
back to router 3.
