Hi subbu,

Vlink is very easy. Dont think abt it is being
complicated and all that.
If u have an area border router that cannot directly
connect to the Backbone as with Area 3 in the figure.,
then u will need to configure a Vlink between this ABR
and another ABR that is connected to the backbone.

That is all.
If this is done, OSPF routing protocol will treat the
area (ARea3 in this case) as though it is directly
connected to the backbone.

Bye
Siva
