The project takes its named 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 has been inactive since 2005. The Quagga tree aims to build a more involved community for Quagga than the centralized development-model which GNU Zebra followed.
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 (ISIS)
- 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.
Google has contributed to Quagga: most of the redone to ISIS and BGP multipath. http://code.google.com/p/google-quagga/source/browse
