system-view
—
Enter OSPF view
ospf [ process-id [ router-id
router-id ] ]
Required
Configure to filter the
received routes
filter-policy { acl-number |
ip-prefix ip-prefix-name |
gateway ip-prefix-name }
import
Required
By default, OSPF does
not filter received
routing information.
Note:
OSPF is a dynamic routing protocol based on link state, with routing information
hidden in LSAs. Therefore, OSPF cannot filter any advertised or received LSA. In fact,
the filter-policy import command filters the routes calculated by OSPF; only the
routes passing the filter can be added to the routing table.
