can any one help me regarding this ospf topology
Question is i want to achieve route for 3.3.3.3/32 via R1 , even from R2 router, but currently R1 is receiving via R1-R3 and R2 is receiving via R2-R3

Because of the OSPF path selection rule, R2 will always prefer the intra-area route via R3 over the inter-area route via R1.

One (real world design) option would be to add an area 100 link between R1 and R2 (e.g. dot1Q) and increase the cost of R2's Fa0/1.

If this is Lab Exam preparation, you may ask the proctor if a virtual link R3-R1 and putting R3's loopback into area 0 would be acceptable ;-)
