Import or export filters may depend on route RPKI status (using
<cf/roa_check()/ operator). In contrast to to other filter operators,
this status for the same route may change as the content of ROA tables
changes. When this option is active, BIRD activates automatic reload of
affected channels whenever ROA tables are updated (after a short settle
time). When disabled, route reloads have to be requested manually. The
option is ignored if <cf/roa_check()/ is not used in channel filters.
Note that for BGP channels, automatic reload requires
