HI all,

This might be a basic one, but I am just trying to understand given a chance
which is best to use GRE tunnel or Virtual links in OSPF. Also under which
circumstance GRE is preffered or the only solution over Virtual link.

to start with ..

1. GRE is used when there is a Stub area between the disjoint area

could any one add more to this ?

Thank you,
Venkatesh
