It can easily handle +full Internet routing tables and is suitable for use on hardware ranging from +cheap SBCs to commercial grade routers. It is actively used in production by +hundreds of companies, universities, research labs and governments. + +FRR is distributed under GPLv2, with development modeled after the Linux +kernel. Anyone may contribute features, bug fixes, tools, documentation +updates, or anything else. + +FRR is a fork of `Quagga <http://www.quagga.net/>`_. + +.. _how-to-get-frr: + +How to get FRR +============== + +The official FRR website is located at |PACKAGE_URL| and contains further +information, as well as links to additional resources. + +Several distributions provide packages for FRR. Check your distribution's +repositories to find out if a suitable version is available. + +Up-to-date Debian & Redhat packages are available at https://deb.frrouting.org/ +& https://rpm.frrouting.org/ respectively. + +For instructions on installing from source, refer to the +`developer documentation <http://docs.frrouting.org/projects/dev-guide/en/latest/>`_. + + +.. _about-frr: + +About FRR +========= + +FRR provides IP routing services. Its role in a networking stack is to exchange +routing information with other routers, make routing and policy decisions, and +inform other layers of these decisions. In the most common scenario, FRR +installs routing decisions into the OS kernel, allowing the kernel networking +stack to make the corresponding forwarding decisions. + +In addition to dynamic routing FRR supports the full range of L3 configuration, +including static routes, addresses, router advertisements etc. It has some +light L2 functionality as well, but this is mostly left to the platform. This +makes it suitable for deployments ranging from small home networks with static +routes to Internet exchanges running full Internet tables. + +FRR runs on all modern \*NIX operating systems, including Linux and the BSDs. +Feature support varies by platform; see the :ref:`feature-matrix`. + +System Requirements +------------------- + +System resources needed by FRR are highly dependent on workload. Routing +software performance is particularly susceptible to external factors such as: + +* Kernel networking stack +* Physical NIC +* Peer behavior +* Routing information scale + +Because of these factors - especially the last one - it's difficult to lay out +resource requirements. + +To put this in perspective, FRR can be run on very low resource systems such as +SBCs, provided it is not stressed too much. If you want to set up 4 Raspberry +Pis to play with BGP or OSPF, it should work fine. If you ask a FRR to process +a complete internet routing table on a Raspberry Pi, you will be disappointed. +However, given enough resources, FRR ought to be capable of acting as a core IX +router. Such a use case requires at least 4gb of memory and a recent quad-core +server processor at a minimum. + +If you are new to networking, an important thing to remember is that FRR is +control plane software. It does not itself forward packets - it exchanges +information with peers about how to forward packets. Forwarding plane +performance largely depends on choice of NIC / ASIC. + + +System Architecture +------------------- + +.. index:: + pair: architecture; FRR + +Traditional routing software is made as a one process program which provides +all of the routing protocol functionalities. FRR takes a different approach. +FRR is a suite of daemons that work together to build the routing table. Each +major protocol is implemented in its own daemon, and these daemons talk to a +middleman daemon (*zebra*), which is responsible for coordinating routing +decisions and talking to the dataplane. + +This architecture allows for high resiliency, since an error, crash or exploit +in one protocol daemon will generally not affect the others. It is also +flexible and extensible since the modularity makes it easy to implement new +protocols and tie them into the suite. Additionally, each daemon implements a +plugin system allowing new functionality to be loaded at runtime. + +An illustration of the large scale architecture is given below. + +:: + + +----+ +----+ +-----+ +----+ +----+ +----+ +-----+ + |bgpd| |ripd| |ospfd| |ldpd| |pbrd| |pimd| |.....| + +----+ +----+ +-----+ +----+ +----+ +----+ +-----+ + | | | | | | | + +----v-------v--------v-------v-------v-------v--------v + | | + | Zebra | + | | + +------------------------------------------------------+ + | | | + | | | + +------v------+ +---------v--------+ +------v------+ + | | | | | | + | *NIX Kernel | | Remote dataplane | | ........... | + | | | | | | + +-------------+ +------------------+ +-------------+ + + +All of the FRR daemons can be managed through a single integrated user +interface shell called *vtysh*. *vtysh* connects to each daemon through a UNIX +domain socket and then works as a proxy for user input. In addition to a +unified frontend, *vtysh* also provides the ability to configure all the +daemons using a single configuration file through the integrated configuration +mode. This avoids the overhead of maintaining a separate configuration file for +each daemon. + +FRR is currently implementing a new internal configuration system based on YANG +data models. When this work is completed, FRR will be a fully programmable +routing stack. + + +.. index:: + pair: platforms; FRR + pair: operating systems; FRR + +.. _supported-platforms: + +Supported Platforms +------------------- + + +Currently FRR supports GNU/Linux and BSD. Porting FRR to other platforms is not +too difficult as platform dependent code should be mostly limited to the +*Zebra* daemon. Protocol daemons are largely platform independent. Please let +us know if you can get FRR to run on a platform which is not listed below: + +- GNU/Linux +- FreeBSD +- NetBSD +- OpenBSD + +Versions of these platforms that are older than around 2 years from the point +of their original release (in case of GNU/Linux, this is since the kernel's +release on https://kernel.org/) may need some work. Similarly, the following +platforms may work with some effort: + +- MacOS + +Recent versions of the following compilers are well tested: + +- GNU's GCC +- LLVM's Clang +- Intel's ICC + +.. _unsupported-platforms: + +Unsupported Platforms +--------------------- + +In General if the platform you are attempting to use is not listed above then +FRR does not support being run on that platform. The only caveat here is that +version 7.5 and before Solaris was supported in a limited fashion. + +.. _feature-matrix: + +Feature Matrix +^^^^^^^^^^^^^^ + +The following table lists all protocols cross-referenced to all operating +systems that have at least CI build tests. Note that for features, only +features with system dependencies are included here; if you don't see the +feature you're interested in, it should be supported on your platform. + +.. role:: mark + +.. comment - the :mark:`X` pieces mesh with a little bit of JavaScript and + CSS in _static/overrides.{js,css} respectively. The JS code looks at the + presence of the 'Y' 'N' '≥' '†' or 'CP' strings. This seemed to be the + best / least intrusive way of getting a nice table in HTML. The table + will look somewhat shoddy on other sphinx targets like PDF or info (but + should still be readable.) +
