A link state protocol generates routes based on Link-State Databases (LSDBs). The
filter-policy does not affect Link State Advertisements (LSAs) or the integrity of
LSDBs. The commands of filter-policy import and filter-policy export are different.
To advertise routes, you can run the filter-policy export command on a device to control
whether the device advertises the routes imported by a specific routing protocol (such
as RIP) from other routing protocols. If the device has not imported any route in
Import mode, it will not add LSAs or Link State Protocol Data Units (LSPs)
corresponding to the imported routes to its LSDB. The device, however, can advertise
LSAs that carry the routing information discovered by the specific routing protocol
itself to other routers.
NOTE
l BGP has powerful filtering function. For details of BGP configuration, refer to
l You can run the filter-policy command and the import-route command with different parameters for
RIP, OSPF, IS-IS, and BGP. For details, refer to related configurations.
