Command Manual – Routing Protocol
Quidway S8500 Series Routing Switches
routing-protocol: Protocol advertising the routing information, including direct, isis,
bgp, rip and static at present.
Description
Use the filter-policy export command to configure the rule used by OSPF to filter
advertised routing information.
Use the undo filter-policy export command to cancel the filtering rules that have been
set.
By default, no filtering of the advertised routing information is performed.
In some cases, it may be required that only the routing information meeting some
conditions can be advertised. Then, the filter-policy command can be used to set the
filtering conditions for the routing information to be advertised. Only the routing
information passing the filtration can be advertised.
This command takes effect on the routes imported by OSPF using the import-route
command. If the routing-protocol argument is specified, only the routes imported from
this specified protocol are filtered. If the routing-protocol argument is not specified, all
imported routes are filtered.
Related command: acl, ip ip-prefix.
