Command Manual - Routing Protocol
Quidway S6500 Series Ethernet Switches Chapter 3 OSPF Configuration Commands
Huawei Technologies Proprietary
3-31
Description
Using filter-policy export command, you can configure the ASBR router to filter the
external routes imported to the OSPF. This command only takes effect on ASBR
routers.
Using undo filter-policy export command, you can cancel the filtering rules that have
been set.
By default, OSPF does not receive the routes distributed by other routing protocol.
 Note:
z The filter-policy export command only takes effect to the routes imported by the
import-route command. If you configure the switch with only the filter-policy
export command, but without configuring the import-route command to import
other external routes (including OSPF routes of different process), then the
filter-policy export command does not take effect.
z If the filter-policy export command does not specify to filter which type of routes, it
takes effect for all the routes imported by the import-route.
For the related commands, see acl, ip ip-prefix.

# Configure ospf to only import the routes by acl 2000.
