Address Summary A configured address range specifies what addresses are contained within an

become unreachable. This is because all inter-area traffic must go through the
backbone. In fact, the backbone is responsible for all inter-area routing
information distribution.
It is possible that an area cannot be connected directly to the backbone; in this
case a virtual link is used (see Figure 3.53). To establish or maintain the
connectivity of the backbone, virtual links can be configured through non-
