Configuring OSPF route redistribution
1. Configure route redistribution into OSPF
On a router running OSPF and other routing protocols, you can configure OSPF to redistribute
routes from other protocols such as RIP, BGP, static, and direct routes, and advertise them in
Type-5 LSAs or Type-7 LSAs.
By filtering redistributed routes, OSPF translates only permitted routes into Type-5 LSAs or Type-7
LSAs for advertisement.

4. 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.
NOTE:
Only active routes can be redistributed. You can use the display ip routing-table protocol command to
v
iew route state information.
2. 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.
