What is the desired result? We have an open source VXLAN overlay technology called LNV (Lightweight Network Virtualization) that might fit the bill if you are interested in that. http://docs.cumulusnetworks.com/display/DOCS/Lightweight+Network+Virtualization+-+LNV We might also support EVPN in the future and that will probably mean that it will be supported in Quagga. LNV is not dependent on Quagga (it does not care what the fabric is). You can use it with OSPF, BGP, static routes, or even Bird instead of Quagga.
