Configuring NSSA Settings

Use the OSPF / NSSA Settings page to configure a not-so-stubby area (NSSA), and
to control the use of default routes for ABRs and ASBRs, or external routes learned
from other routing domains and imported via an ABR. (For a detailed description of
NSSA areas, refer to "Configuring OSPF Areas" on page 3-238.)
Command Attributes
• Area ID – Identifier for an not-so-stubby area (NSSA).
• Default Information Originate – An NSSA ASBR originates and floods Type-7
external LSAs throughout its area for known network destination outside of the AS.
However, you can also configure an NSSA ASBR to generate a Type-7 "default"
route to areas outside of the AS, or an NSSA ABR to generate a Type-7 "default"
route to other areas within the AS. (Default: Disabled)
• No Redistribution – The Redistribute Configuration page (page 3-253) is used to
import information from other routing domains (or protocols) into the AS. However,
when the router is an NSSA ABR, you can choose whether or not to accept external
routes learned from routers in other OSPF areas into the NSSA. (Default: Enabled)
