Every computer running SCO TCP/IP has an Internet routing table.
It is stored in the operating system kernel and is
referred to as the ``kernel routing table'' or sometimes as the
``kernel forwarding table''.
This table consists of a series of entries.
Each entry consists of multiple fields. The fields pertinent to this
discussion are:
destination network IP address
network mask (netmask)
next hop (gateway), which is the next machine which knows how to reach the
ultimate destination machine
identity of network interface through which the packet is sent to
reach the next hop
The following sections show examples of how the routing table
is used for
direct
and
indirect
routing.
