OSPF Area Parameters

You can optionally configure several OSPF area parameters. These parameters include authentication for
password-based protection against unauthorized access to an area, stub areas, and NSSAs. Stub areas are
areas into which information about external routes is not sent. Instead, the ABR generates a default
external route into the stub area for destinations outside the autonomous system (AS). An NSSA does
not flood all LSAs from the core into the area, but can import AS external routes within the area by
redistribution.

11-14
Example 11-6 shows the output of the show ip ospf interface privileged EXEC command.
Hello due in 00:00:01
Hello due in 00:00:05

Chapter 11 Configuring Networking Protocols
Purpose
(Optional) Blocks flooding of OSPF LSA packets to the
interface. By default, OSPF floods new LSAs over all
interfaces in the same area, except the interface on which
the LSA arrives.
Returns to privileged EXEC mode.
Displays OSPF-related interface information.
(Optional) Saves your entries in the configuration file.
