Video Description

Used to solve basically two issues:

Connect an area that doesn't have physical connectivity to the backbone.
"Repair" a discontiguous backbone.

Logical connections, vaguely similar to a tunnel. 

They do not encapsulate traffic.

They are configured between ABRs, where one of them has "contact" with area 0, they can't be formed using "stub" areas. This connection becomes a point-to-point "link: between them, type 1 LSAs are generated for that new area 0 link. The messages between them are "unicast"

The cost of the virtual link depends on the path to connect those ABRs
