3. Configure a
preference for OSPF.
preference [ ase ] [ route-policy
route-policy-name ] value
By default, the preference of OSPF
internal routes is 10 and the preference
of OSPF external routes is 150.
Configuring OSPF route redistribution
On a router running OSPF and other routing protocols, you can configure OSPF to redistribute static
routes, direct routes, or routes from other protocols, such as RIP, IS-IS, and BGP. OSPF advertises the
routes in Type-5 LSAs or Type-7 LSAs. In addition, you can configure OSPF to filter redistributed routes so
that OSPF advertises only permitted routes.
IMPORTANT:
The import-route bgp command redistributes only EBGP routes. Because the import-route bgp
allow-ibgp command redistributes both EBGP and IBGP routes, and mi

loops, use it with
caution.

3. Configure OSPF to
redistribute routes from
another routing protocol.
import-route protocol [ process-id |
all-processes | allow-ibgp ]
[ allow-direct | cost cost | nssa-only |
route-policy route-policy-name | tag tag
| type type ] *
By default, no route redistribution
is configured.
This command redistributes only
active routes. To view information
about active routes, use the
display ip routing-table protocol
command.
4. (Optional.) Configure
OSPF to filter redistributed
routes.
filter-policy { acl-number | prefix-list
prefix-list-name } export [ protocol
[ process-id ] ]
By default, OSPF accepts all
redistributed routes.
Configuring OSPF to redistribute a default route
The import-route command cannot redistribute a default external route. Perform this task to redistribute a
default route.
