Parameters
acl-number: Number of an ACL used to match the destination address in routing information, in the
range of 2000 to 3999.
ip-prefix-name: Name of the address prefix list used to match the destination address in routing
information, a string of up to 19 characters.
protocol: Filters outgoing routes redistributed from the routing protocol, including direct, rip, and static.
For details about IP prefix list information, refer to the section IP Route Policy Configuration.
Description
Use the filter-policy export command to configure the filtering of outgoing redistributed routes.
Use the undo filter-policy export command to disable such filtering.
By default, filtering of outgoing redistributed routes is not configured.
In some cases, it may be required that only the routing information meeting some conditions can be
advertised. You can use the filter-policy command to set the filtering conditions for the routing
information to be advertised. Only the routing information passing the filtration can be advertised.
This command filters routes redistributed (with the import-route command) by OSPF. If the protocol
argument is specified, this command filters only the outgoing routes redistributed from the protocol. If
the protocol argument is not specified, the outgoing routes redistributed from all protocols will be
filtered.
Related commands: acl, ip ip-prefix.
For details about ACL, refer to the section ACL Operation.
