Configuring OSPF Area Parameters
The IA allows configuration of various OSPF area parameters, including stub areas, stub
cost, and authentication method. Stub areas are areas into which information on external
routes is not sent. Instead, there is a default external route generated by the ABR, into the
stub area for destinations outside the autonomous system. Stub cost specifies the cost to
be used to inject a default route into a stub area. An authentication method for OSPF
packets can be specified on a per-area basis.
To configure OSPF area parameters, enter the following commands in the Configure
mode:
Specify an OSPF stub area.
Specify the cost to be used to inject a
default route into an area.
Specify the authentication method
to be used by neighboring OSPF
routers.
