Description
Use the filter-policy export command to filter the advertised routes and only the
routes passing the filter can be advertised by BGP.
Use the undo filter-policy export command to cancel the filtration to the
advertised routes.
By default, the advertised routes are not filtered.
If the protocol argument 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 protocol argument is not specified, the imported route
generated by any protocol will be filtered.
