To generate a default external route into an Open Shortest Path First (OSPF) routing domain, use the default-information originate command. To disable this feature, use the no form of this command.
default-information originate [ always ] [ route-map map-name ]
no default-information originate [ always ] [ route-map map-name ]

Use this command to assign a default route for redistributed routes. Whenever you use the redistribute command to redistribute routes into an OSPF routing domain, Cisco NX-OS automatically becomes an Autonomous System Boundary Router (ASBR). However, an ASBR does not, by default, generate a default route into the OSPF routing domain.
Use the route-map keyword to filter redistributed routes so that Cisco NX-OS generates a default route only for routes that pass the route map. Use the always keyword to generate the default route regardless of whether the default route is in the route table.
Note The default-information originate command ignores match statements in the optional route map.
This command requires the LAN Base Services license.
This example shows how to configure the default route redistributed into the OSPF routing domain for the Enhanced Interior Gateway Protocol (EIGRP):
