 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 commands: filter-policy import.
