What do you need to know about iproute2?

iproute2 is a collection of userspace utilities for controlling and monitoring various aspects of networking in the Linux kernel, including routing, network interfaces, tunnels, traffic control, and network-related device drivers. iproute2 is an open-source project released under the terms of version 2 of the GNU General Public License.

Who is the author of the iproute2 utility suite?

IPROUTE2 Utility Suite Documentation This docvumentation covers the ip utility from IPROUTE2. This utility is written by Alexey N. Kuznetsov who also wrote the IPv6 and IPv4 routing code for Linux 2.2. This is the utility he uses for manipulating the Linux 2.2-2.6 network interface code.

How to change route path in iproute2 utility suite?

9.5.3 ip route replace — change route or add new one. 9.5.4 ip route delete 9.5.5 ip route show 9.5.6 ip route flush – alows group deletion of routes 9.5.7 ip route get – obtain route pathing 9.6 ip rule — routing policy database management.

Is the iproute2 project an open source project?

iproute2 is an open-source project released under the terms of version 2 of the GNU General Public License. Its development is closely tied to the development of networking components of the Linux kernel.

iproute2 is usually shipped in a package called iproute or iproute2 and consists of several tools, of which the most important are ip and tc. ip controls IPv4 and IPv6 configuration and tc stands for traffic control.

Who is the author of iproute2 in Linux?

Iproute2 is a collection of utilities for controlling TCP / IP networking and traffic control in Linux. It is currently maintained by Stephen Hemminger . The original author, Alexey Kuznetsov, is well known for the QoS implementation in the Linux kernel.

Why does the etc / net project support iproute2?

The /etc/net project aims to support most modern network technologies, as it doesn’t use ifconfig and allows a system administrator to make use of all iproute2 features, including traffic control.

Overview iproute2 is the Linux networking toolkit that replaced net-tools (ifconfig, route, arp etc.) Old style network utilities like ifconfig and route are still there just for backwards compatibility and do not provide access to new features like policy-based routing or network namespaces.

Are there configuration files in / etc / iproute2?

There are configuration files in /etc/iproute2, mainly for assinging symbolic names to network stack entities such as routing tables. Those files are re-read every time you run the ip command and you don’t need to do anything to apply the changes.

How to equalize a route in iproute2?

Equalize works only if the appropriate kernel configuration option is chosen or if the kernel is patched. Two more commands, prepend and append do exist. Prepend does the same thing as the classic route add command by adding the route even if another route to the same destination already exists. ip route del has the same arguments as ip

Note that iproute2 has been a standard Linux toolsince the early 2000’s. It’s included in every distro by default, or at least available from the repos (OpenWRT is one of the cases). iproute2 was originally written by Alex Kuznetsov and is now maintained by Stephen Hemminger.

How does iproute2 communicate with the Linux kernel?

iproute2 utilities communicate with the Linux kernel using the netlink protocol. Some of the iproute2 utilities are often recommended over now-obsolete net-tools utilities that provide the same functionality. Below is a table of obsolete utilities and their iproute2 replacements.

As of December 2013, iproute2 is maintained by Stephen Hemminger. The original author, Alexey Kuznetsov, was responsible for the quality of service (QoS) implementation in the Linux kernel.
