Hello @ranga2002 ,
to build a virtual link the two routers need to have a standard area in common, one of them must be connected to area 0 and the other one must be connecte to the area that is missing a link to area 0.
The virtual link is built using OSPF RID each side must configure the transit area and the RID of the remote router.
So it should be:
a) configured on R2, R3
R2
router ospf 2
area 0.0.0.1 virtual-link 10.4.1.1
R3
router ospf 2
area 0.0.0.1 virtual-link 10.1.2.1
note: the OSPF RID is the highest IP address on router each router R2, R3 points to the remote OSPF RID in configuring the virtual link.
No mask is required the virtual-link is a logical point-to-point link that extends area 0 via transit area .
Hope to help
Giuseppe
