The if-match mode of at least one list item of the ip-prefix should be the permit
mode. The list items of the deny mode can be defined first to rapidly filter the
routing information not satisfying the requirement, but if all the items are in the
deny mode, any routes will not pass the ip-prefix filtering. You can define an item
of permit 0.0.0.0/0 less-equal 32 after the multiple list items in the deny mode so
as to let all the other routes pass the filtering (If less-equal 32 is not specified, only
the default route will be matched).
