fedora
Calendar Grey November 19, 2016
Dist Fedora Esm H88
Fedora 25 enhances its quagga package to fix vulnerabilities and resolve systemd compatibility challenges. Use dnf for installation.
This update addresses multiple security problems and fixes systemd dependencies.

Summary

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, and RIPng.

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.
