How to create a manual interarea summary route

OSPF does not know the concept of auto-summarization. The following summarizes the features of a stub area: * ABRs create a default route, using a Type 3 LSA, listing subnet and mask , and flood that into the stub area. Routers inside the stub area cannot redistribute external routes into the stubby area, because that would require a Type 5 LSA. The default route has a metric of 1 unless otherwise configured. However, interarea routes are also [HOST] must the administrator do to fix this problem? Static routes are manually configured routes that defines explicit path between two devices.
