By far, the route policy supports importing the routes discovered by the following
protocols into the routing table:
direct: The hop (or host) to which the local interface is directly connected.
static: Route configured statically
rip: Route discovered by RIP
ospf: Route discovered by OSPF
ospf-ase: External route discovered by OSPF
ospf-nssa: NSSA route discovered by OSPF
isis: Route discovered by IS-IS
bgp: Route acquired by BGP
By default, the filtering of the received and advertised routes will not be performed.
