Managing Areas
Network areas determine the regions within which routes are distributed to other routers. The subnets at a
particular router can be added to its OSPF Area. The router will advertise these subnets to all routers in its area.
OSPF areas must be designed such that no single link failure will cause the network to be split into two disjointed
networks.
A router can be part of multiple areas and function as a gateway between areas. When multiple areas are used on
a network, area zero (0) is the backbone area. All areas must have a router connecting them to area zero (0).
