ip command from the iproute2 package is now the Linux network management tool.
Not only does it combine the functionality of the old
and other commands; it also supports networking features that the old tools still
do not support. Some examples of missing functionality are multiple addresses on the
same interface, policy-based routing, VRFs, and more.
A major issue with the iproute2 package is its documentation. The man pages are extremely terse:
only basic descriptions of the options, and almost no examples.
While for an experienced user, this level of documentation is enough, for most novice users, it is not.
Many users continue using
ifconfig out of habit and familiarity,
and ultimately miss out on the powerful features of the
Historically, community-maintained documentation such as http://policyrouting.org/iproute2-toc.html and https://www.lartc.org/howto/ filled the documentation void. Unfortunately, most of those documents have not been actively expanded since early or mid 2000s and are woefully out of date. Because of this, they are missing many valuable and exciting new features. Finally, many of these documentation projects were never released under a free license, which makes them almost impossible to fork and maintain if the original maintainers abandon them.
This document aims to provide a comprehensive, easy to use, free (as in freedom) guide to iproute2.
Originally this was named "iproute2 cheatsheet", but was renamed to "Task-centered iproute2 manual" as the size and scope expanded.
