type-3 LSA injection with ospf virtual-link

Hi,all

Recently,I've ran into a problem about ospf virtual-link while doing the lab of ospf.The situation is simply like below:

when the virtaul-link between R2-R4 is done I've found neither R2 nor R3 which both as the  ABR for area0 and area1 would not inject the type-3 LSA of the prefix 45.1.1.0,as a result, the referred type-3 LSA was injected by R4 only.

R2:

R2#sh ip ospf  database | in 45
45.1.1.0        4.4.4.4         7     (DNA) 0x80000001 0x00B844
45.1.1.0        4.4.4.4         363         0x80000002 0x00B645

R3:

R3#sh ip os database | in 45
45.1.1.0        4.4.4.4         9     (DNA) 0x80000001 0x00B844
45.1.1.0        4.4.4.4         492         0x80000002 0x00B645

Now I've got a little confused ablout this,is here some specific mechanisms of ospf virtual-link or other possibilities?
