Configuring OSPF Stub Areas
Stub areas do not receive information on external routes. Instead, the Area Border
Router (ABR) generates a default external route into the stub area for destinations
outside the Autonomous System (AS). A stub area allows a default route, intra-area
routes, and inter-area routes, but disallows autonomous system (AS) external routes,
virtual links, and autonomous system boundary router (ASBR) routes.
Use the following steps to configure a stub area:
1. Issue the router ospf command in Global Configuration mode to enter OSPF
Router Configuration mode.
