Quagga (software)

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.^[1][2]

Quagga is distributed under the terms of the GNU General Public License (GPL).

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
• babeld, implementing the Babel routing protocol, including support for both IPv4 and IPv6 and for both wired networks and wireless mesh networks.

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 Quagga: most of the redone to ISIS and BGP multipath. https://code.google.com/p/google-quagga/source/browse
