# 5.2.  Conceptual Sending Algorithm
# </PRE>
# <PRE>
#    Next-hop determination for a given unicast destination operates as
#    follows.  The sender performs a longest prefix match against the
#    Prefix List to determine whether the packet's destination is on- or
#    off-link.  If the destination is on-link, the next-hop address is the
#    same as the packet's destination address.  Otherwise, the sender
#    selects a router from the Default Router List (following the rules
#    described in Section 6.3.6).  <U><B>If the Default Router List is empty,</B></U>
#    <U><B>the sender assumes that the destination is on-link.</B></U>
