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.

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 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.
