conditions for the routing information to be received. Only the routing information
passing the filter can be received.
The filter-policy import command filters the routes calculated by OSPF. Only the
routes passing the filter can be added to the routing table. The routes can be filtered
based on next hop and destination address.
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. This command
is used much less in OSPF than in distance-vector routing protocols.
