I am sorry I wish a small correction has to be made to my previous posting.
I give the corected one here.
On R2 create a point-to-multipoint subinterface.
On R3 create a point-to-point subinterface.
On R4 being a physical interface use the command 'ip ospf network
point-to-point' on the interface.
Make the R2 as DR by using the command "ip ospf pri 0" on R3 and R4
thanks
