Note:
z The filter-policy export command takes effect only on the routes imported
through the import-route command. If the filter-policy export command is
configured while the import-route command is not configured to import other
non-IS-IS routes, the filter-policy export command does not take effect.
z If the protocol argument is not provided in the filter-policy export command, the
command takes effect on all the routes imported to the local device using the
import-route command.
Related command: filter-policy import.
