Description
Using the filter-policy export command, you can configure how OSPF filters
the advertised routing information. Only the routing information that meets these
conditions is advertised.
Using the undo filter-policy export command, you can cancel the filtering
rules. By default, no filtering of the distributed routing information is performed.
Related commands: acl, ip ip-prefix.
