Description
Use the filter-policy export command to define an outbound route filtering policy. Only
routes passing the filter can be advertised in the update messages.

By default, RIPng does not filter any outbound routing information.
With the protocol argument specified, only routing information redistributed from the
specified routing protocol will be filtered. Otherwise, all outgoing routing information will
be filtered.
