Personally I would like to see more work on all three opensource implementations, i.e. BIRD, OpenBGPd and Quagga.
http://opensourcerouting.org/ to the rescue?
Hi, I'm David Lamparter, employed at the OpenSourceRouting (OSR) project to maintain Quagga. I can tell you that the OSR's interest is in providing a stable open-source routing platform for actual switches/routers (with either a software or hardware forwarding plane). Quagga and BIRD were considered equally; Quagga's single-RIB design and existence of isisd were what tipped the scales. We primarily perform conformance and scale testing and fix/enhance in those areas; also we support 3rd parties in cleaning and submitting Quagga patches/features. OSPF and IS-IS are stronger targets currently since they need more work than BGP, and also Euro-IX already did much of the latter. Merging that is on the TODO, but it's a lot of work. Even as a Quagga maintainer, I must currently recommend against using mainline Quagga as a route server. Please use Euro-IX Quagga, and if you can/want, convince your decisionmakers to support Chris Hall on that -- I've been told future work on the Euro-IX Quagga branch is not certain. There's been a BoF on RIPE64 with OSR, BIRD and Quagga involvement. There'll be one at RIPE65 again I think. Either way if you have questions, feel free to ask. -David
