Quagga (software)

Quagga is an open-source routing software suite that provides implementations of various routing protocols. It allows a Unix-like operating system to function as a router, enabling it to participate in complex network environments. Quagga supports a wide range of routing protocols, including RIP, OSPF, BGP, and IS-IS.

The software is designed with a modular architecture, featuring a core daemon called zebra that acts as a protocol-independent route manager. Each routing protocol is implemented as a separate daemon that communicates with zebra to exchange routing information and update the system's routing table. This modularity allows administrators to selectively enable or disable routing protocols as needed.

Quagga is often used in network environments where dynamic routing is required, such as in large enterprise networks or by Internet service providers (ISPs). It is a popular alternative to proprietary routing software, offering a flexible and customizable solution for network routing. The open-source nature of Quagga allows for community-driven development and support, leading to continuous improvements and bug fixes. Quagga is typically configured through text-based configuration files, offering granular control over routing parameters. Because it adheres to standard routing protocols, Quagga can interoperate with other routing devices from various vendors.
