Roberts already done that. He has his neighbor statements in and put the
"ip ospf priority 0" on R4 and R5's Serial Interface. This seems like an
inverse ARP issue. It's easy to fix with map statements but the
instructions say you can't use them.

Subject: RE: OSPF and frame relay issues
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.
