Configuring OSPF Route Redistribution
Configure route redistribution into OSPF
If the router runs OSPF and other routing protocols, you can configure OSPF to redistribute RIP, IS-IS,
BGP, static, or direct routes and advertise these routes in Type-5 LSAs or Type-7 LSAs.
By filtering redistributed routes, OSPF translates only routes not filtered out into Type-5 LSAs or Type-7
LSAs for advertisement.
Follow these steps to configure OSPF route redistribution:

Required
Not configured by
default.
Configure OSPF to filter
redistributed routes before
advertisement
filter-policy { acl-number | ip-prefix
ip-prefix-name } export [protocol
[ process-id ] ]
Optional
Not configured by
default.
Only active routes can be redistributed. You can use the display ip routing-table protocol command
to display route state information.
Configure OSPF to redistribute a default route
Using the import-route command cannot redistribute a default external route. To do so, you need to
use the default-route-advertise command.
Follow these steps to configure OSPF to redistribute a default external route:
