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.
Follow these steps to configure OSPF route redistribution:
To do… Use the command…
Remarks
Enter system view system-view
—
Enter OSPF view
ospf [ process-id | router-id router-id |
vpn-instance instance-name ] *
—
Configure OSPF to redistribute
routes from another protocol
import-route protocol [ process-id |
all-processes | allow-ibgp ] [ cost cost | type
type | tag tag | route-policy
route-policy-name ] *
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.
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.
Follow these steps to configure OSPF to redistribute a default external route:
To do… Use the command…
Remarks
Enter system view system-view
