quagga 0.99.20

Quagga is a routing software suite, providing implementations of OSPFv2, OSPFv3, RIP v1 and v2, RIPv3 and BGPv4 for Unix OS.
Quagga is a routing software suite, providing implementations of OSPFv2, RIP v1 and v2, RIPv3 and BGPv4, OSPFv3 for Unix platforms, particularly FreeBSD, Linux, Solaris and NetBSD. Quagga is a fork of GNU Zebra which was developed by Kunihiro Ishiguro. The Quagga tree aims to build a more involved community around Quagga than the current centralised model of GNU Zebra.

The Quagga architecture consists of a core daemon:


Which acts as an abstraction layer to the underlying Unix kernel and presents the Zserv API over a Unix or TCP stream to Quagga clients. It is these Zserv clients which typically implement a routing protocol and communicate routing updates to the zebra daemon. Existing Zserv clients are:

implementing OSPFv2
implementing RIP v1 and V2
implementing OSPFv3 (IPv6)
implementing RIP v3 (IPv6)
implementing BGPv4+ (including address family support for multicast and IPv6)

Additionally, the Quagga architecture has a rich development library to facilitate the implementation of protocol/client daemons, coherent in configuration and administrative behaviour.

Quagga daemons are each configurable via a network accessible CLI (called a 'vty'). The CLI follows a style similar to that of other routing software. There is an additional tool included with Quagga called 'vtysh', which acts as a single cohesive front-end to all the daemons, allowing one to administer nearly all aspects of the various Quagga daemons in one place.
