ABR. (For a detailed description of NSSA areas, refer to “Configuring
OSPF Areas” on page 3-291.)
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 3-310) 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)
Note:
This router supports up 16 areas, either normal transit areas, stubs,
or NSSAs.
