Does your routing table show that R4 prefers the VL as its next hope? That's the problem.

I am trying to understand ospf load balancing following is my diagram
Area 0 --------- area 5
R1 -------- R2 area 6 R3 ------ R4
---------
Please note there are 2 links between R2 and R3
What I have noticed in the routing table that traffic from R1 and R4 are not load balancing IA route between R2 and R3 even though I have configured ip ospf costs same.
Any idea what needs to be done? Following is my config
R2
router ospf 5
router-id 1.1.2.2
log-adjacency-changes
area 6 virtual-link 1.1.3.3
network 1.1.2.0 0.0.0.255 area 0
network 1.1.20.0 0.0.0.255 area 6
network 1.1.6.0 0.0.0.255 area 6
network 1.1.4.0 0.0.0.255 area 0
maximum-paths 6
int e0
ip add 1.1.20.2 255.255.255.0

end
