Note:
OSPF is a dynamic routing protocol based on link state, with routing information
hidden in LSAs. Therefore, OSPF cannot filter any advertised or received LSA. In fact,
the filter-policy import command filters the routes calculated by OSPF; only the
routes passing the filter can be added to the routing table.
