SUMMARY = "BGP/OSPF/RIP routing daemon"
DESCRIPTION = "Quagga is a routing software suite, providing \
implementations of OSPFv2, OSPFv3, RIP v1 and v2, RIPv3 and BGPv4 for \
Unix platforms, particularly FreeBSD, Linux, Solaris and NetBSD. \
Quagga is a fork of GNU Zebra which was developed by Kunihiro \
Ishiguro. The Quagga tree aims to build a more involved community \
around Quagga than the current centralised model of GNU Zebra."
