It is possible that an area cannot be connected directly to the backbone. In this

case a virtual link is used. To establish or maintain the connectivity of the

backbone, virtual links can be configured through non-backbone areas.

Basically, virtual links are used to connect components that are otherwise not

connected to the backbone.

A virtual link is treated by OSPF as a point-to-point unnumbered network

joining two area border routers. The virtual link must be configured in both of

the area border routers.

A virtual link is defined by the following two parameters:

• The Router ID of the virtual link’s other endpoint

• The non-backbone area the virtual link goes through.
