That is correct. If it is not adjancent/directly
connected or more then 1 hop away then the route-map
policy will be rejected and normal forwarding takes
place (debug policy).
cisco.com has conflicting docs on this. Some say it
has to be adjancent, others say it doesn't. I remember
one saying "it not need be adjancent".
