ospf-nssa, or ospf-ase. Without this parameter, filtering is performed on all
redistributed routes.
Description
Use the filter-policy export command to configure IS-IS to filter all redistributed routes
or routes redistributed from a specified routing protocol.
Use the undo filter-policy export command to disable IS-IS to filter all redistributed
routes or routes redistributed from a specified routing protocol.
By default, IS-IS does not filter any redistributed routing information.
In some cases, it may be required that only the routing information meeting some
conditions be advertised. You may use the filter-policy export command to set the
conditions for filtering redistributed routing information. Only the routing information
passing the filtering can be advertised.
