Describe the routing policy rules in a Linux environment and 'a
rather long and complex, with this article I just want to make an
introduction to what you can do with your linux box and the
commands available in the package iproute2.
"For more info i suggest the site:
"iproute2 is a collection of utilities for controlling TCP and
UDP IP networking and traffic control in Linux, in both IPv4 and
IPv6 networks. It is currently maintained by Stephen Hemminger. The
original author, Alexey Kuznetsov, was responsible for the QoS
implementation in the Linux kernel.
"iproute2 is intended to replace an entire suite of legacy Unix
networking tools (often called "net-tools") that were previously
used for the tasks of configuring network interfaces, routing
tables, and managing the ARP table, but which have not been
developed since 2001""
