Virtual link problem

Hi all,

I was able to get the Virtual link up b/n R5 and R1, but the error message
"%OSPF-4-ERRRCV: Received invalid packet: mismatch area ID, from backbone
area must be virtual-link but not found from 163.1.54.4, Serial0/0/0" keeps
coming on routers R1 and R2. The IP address 163.1.54.4 is assigned to serial
link on R4 connected to area 0.

*My Scenario is -*

*R4*-----area0-------*R5*------area1--------*R3*------area1-------*R1*
------area2-------*R2*
         54.0/24 35.0/24 13.0/24
12.0/24

Loopbacks are 150.1.X.X on each router. X = router number.
Major Network = 163.1.0.0/16

*R2:*
