They are only the Route Engine. You still need a forwarding plane 3 Why look at Open Source for routing, Why now? Reasons for Open Source Software in Routing 1 Popular Open Source Software Overview of Bird, Quagga, OpenBGPd, Xorp 2 Current Status of Quagga Details on where to consider Quagga, where to avoid it 3 What Open Source Routing is doing What we (OpenSourceRouting.org) do on Quagga 4 How you can help Open Source needs your help. And it will help you. 5 4 Reasons why the time is NOW A few reasons to at least start thinking about Open Source Could be much cheaper. You don’t need all the Money features and all the specialized hardware everywhere. All the current buzzwords. And most of it started SDN, with Open Source – and is designed for it.
