Release     : 2.fc27
URL         : http://www.quagga.net
Summary     : Routing daemon
Description :
Quagga is free software that operates TCP/IP-based routing protocols. It takes
a multi-server and multi-threaded approach to resolving the current complexity
of the Internet.

Quagga supports Babel, BGP4, BGP4+, BGP4-, IS-IS (experimental), OSPFv2,
OSPFv3, RIPv1, RIPv2, RIPng, PIM-SSM and NHRP.

Quagga is intended to be used as a Route Server and a Route Reflector. It is
not a toolkit; it provides full routing power under a new architecture.
Quagga by design has a process for each protocol.

Quagga is a fork of GNU Zebra.
