Rodney already gave you another example, but I will give you another.
Even without PHP, say you have LSR that has only default route to a certain
destination. Unless you specifically instruct LSR to do so (mpls ip
default-route), packets destined for this destination will not be labelled.
Packets destined for "known destination" out the same interface will be
labelled as usual.
