acl-number: Number of IP access control list.
ip-prefix-name: Name of ip prefix list.
protocol: Specified protocols advertising routing information which include direct, ospf,

Description
Using filter-policy export command, you can filter the advertised routes and only the
routes passing the filter can be advertised by BGP. Using undo filter-policy export
command, you can cancel the filtration to the advertised routes.
By default, filtration to the received routing information is not configured.
If the parameter protocol is specified, only the imported route generated by the
specified protocol is filtered and the imported routes generated by other protocols are
not affected. If the parameter protocol is not specified, the imported route generated by
any protocol will be filtered.
