"reserved-class1" from the previous example, add a
"member('KNOWN')" statement in the expression.
Beware that classes from reservations are added after: a
"member('reserved-class1')" works only for only-if-required
classes.
.. note::
Beware that the reserved classes are assigned to the processed
packet after all classes with the ``only-if-required`` parameter
set to ``false`` have been evaluated. This has an implication that
these classes must not depend on the statically assigned classes
from the host reservations. If there is a need to create such
dependency, the ``only-if-required`` must be set to ``true`` for
the dependent classes. Such classes are evaluated after the static
classes have been assigned to the packet. This, however, imposes
additional configuration overhead, because all classes marked as
``only-if-required`` must be listed in the ``require-client-classes``
list for every subnet where they are used.
