Quagga (software)


Quagga is a network routing software suite providing implementations of Open Shortest Path First, Routing Information Protocol, Border Gateway Protocol and IS-IS for Unix-like platforms, particularly Linux, Solaris, FreeBSD and NetBSD.
Quagga is distributed under the terms of the GNU General Public License.
In April 2017, FRRouting forked from Quagga aiming for a more open and faster development.

Name

The project takes its name from the quagga, an extinct sub-species of the African zebra. Quagga is a fork of the GNU Zebra project which was developed by Kunihiro Ishiguro and which was discontinued in 2005. The Quagga tree aims to build a more involved community for Quagga than the centralized development-model which GNU Zebra followed.

Components

The Quagga architecture consists of a core daemon which is an abstraction layer to the underlying Unix kernel and presents the Zserv API over a Unix-domain socket or TCP socket to Quagga clients. The Zserv clients typically implement a routing protocol and communicate routing updates to the zebra daemon. Existing Zserv clients are:
Additionally, the Quagga architecture has a rich development library to facilitate the implementation of protocol and client software with consistent configuration and administrative behavior.
Google has contributed to improvements to the IS-IS protocol and added BGP multipath support.
