OSPF Discontiguous Networks

If an OSPF topology is created, where traffic will need to cross a non-backbone area to reach a destination, it is known as a discontiguous network.

The fix for a discontigious network is to ensure that Area 0 is contiguous.

There are workarounds, such as GRE tunnels or a OSPF virtual link.
