acl-number: Specifies the number of access control list matching the

destination address field of routing information, ranging from 1 to 199.

ip-prefix-name: Specifies the name of the address prefix list matching the

destination address field of routing information, ranging from 1 to 19.

protocol: Routing information of which kind of route protocol to be filtered. It

includes direct, ospf, ospf-ase, ospf-nssa, isis, rip, and static at present.

Using the filter-policy export command, you can filter the advertised routes and

only the routes passing the filter can be advertised by BGP. Using the undo

filter-policy export command, you can cancel the filtering to the advertised routes.

By default, the advertised routing information is not filtered.

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.

Use acl 3 to filter the routing information advertised by all BGPs.
