Quagga is a network routing software suite providing implementations of Open Shortest Path First (OSPF), Routing Information Protocol (RIP), Border Gateway Protocol (BGP) and IS-IS for Unix-like platforms, particularly Linux, Solaris, FreeBSD and NetBSD.{{cite book|title=IPv6 in practice|author=Benedikt Stockebrand|publisher=Springer}}{{cite book|title=Linux Networking Cookbook|first=Carla|last=Schroder|publisher=O'Reilly|year=2007|isbn=978-0-596-10248-7|pages=173–203}}
Quagga is distributed under the terms of the GNU General Public License v2 (GPL2).
In April 2017, FRRouting forked from Quagga aiming for a more open and faster development.{{Cite news |title=Welcoming FRRouting to The Linux Foundation |newspaper=Linux.com |date=2017-04-03 |first=Jim |last=Zemlin |url=https://www.linux.com/news/2017/4/welcoming-frrouting-linux-foundation |access-date=2018-06-30}}
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 (zebra) 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:
- ospfd, implementing Open Shortest Path First (OSPFv2)
- isisd, implementing Intermediate System to Intermediate System (IS-IS)
- ripd, implementing Routing Information Protocol (RIP) version 1 and 2;
- ospf6d, implementing Open Shortest Path First (OSPFv3) for IPv6
- ripngd, implementing Routing Information Protocol (RIPng) for IPv6
- bgpd, implementing Border Gateway Protocol (BGPv4+), including address family support for IP multicast and IPv6
- pimd, implementing Protocol Independent Multicast (PIM-SSM) for Source-specific multicast
Additionally, the Quagga architecture has a rich development library to facilitate the implementation of protocol and client software with consistent configuration and administrative behavior.
