In the CCNP-Route Episode a route map statement contained an empty permit statement for redistribution of connected routes in order to permit all others. (I assume there must be an implicit deny??)

In the CCNP- PBR Episode a route map was created that did not contain a permit statement that was empty.
I think this is not very clear. In my search for an answer, this appears to be very unclear to other people as well.
