   1) There is the usual, netmask-based routing yuou're likely to see in   
   a residence.   
      
   2) There are more sophisticated  protocols for rules or   
   learning at layer three. One such is OSPF.   
      
   Effectively, what a router needs to understand is "Given this PDU, which   
   port to I send it on?". The answer may be "no port at all."   
      
   Technically, a canonical router has only two ports.
