You can configure this
R3 and R2 multipoint subinterface.
R4 physical interaface and R2 multipoint subinterface.
OSPF in this configuration work.
In R4 You just need add map statement for both router ( R2,R3)
In R3,R2 same.
Also use neighbor command in ospf configuration in R2.
And adjust priority. R2 should be DR.
All router use same subnet.

R4 R3
Hub and Spoke Topology
R2 Has a PVC to R4 and R3
- R2/R3/R4 Share the 10.10.10.0/27 Network
- R4 Must be configured using a Physical Interface
- R3 & R2 Must be configured using Sub-interfaces
- R2's Serial Subinterface must be configured as a multipoint interface,
not
a Non-broadcast.
- You may not use the "IP OSPF NETWORK" command on R3
I have not been able to get this working and meet all th requirements.
Anyone out there seen this before?
Thanks in advance.
Nate
