Routers

A router is an internetworking device that forwards packets between networks by processing the routing
information included in the packet or datagram (Internet protocol information
from layer 3). The routing information is often processed in conjunction with
the routing table (or forwarding table). A router uses its routing table to
determine where to forward packets. (A destination in a routing table can
include a "null" interface, also known as the "black hole"
interface because data can go into it, however, no further processing is done
for said data.)
