RE: pls help, easy ospf question

On R1 and R4 if you want all the interfaces in a particular area x, then you
need to configure

!
router ospf 1
 network 0.0.0.0 0.0.0.0 area x
!
Not, this
!

router ospf 1

 network 0.0.0.0 255.255.255.255 area x

!

Or, if you want a specific interface then
!

router ospf 1

 network 1.2.3.4 0.0.0.0 area x

!
