The "default-information originate" command will send out a default route
into OSPF originating from that router IF it has a default route in the
table (0.0.0.0 0.0.0.0). No default route already in the table, no sending
default into OSPF. This is so that no black holes occur (i.e. other routers
send all unknown traffic to this router, which doesn't have a default).
If you want the router to always generate a default route, whether it has
one in the routing table already or not, use the "always" keyword.

Thanks for all who responded. I am still confused by this command. DOes
it means the router that this command is run on will advertise itself as
a default router to peers in the OSPF domain? If so I fully understand
it. IF not, then can someone explain how that command works?
