	Hi Renato, I have a patch to support full VRF support on zebra daemon. It is
almost agnostic about the kernel interface. Currently i have a porting layer to
a custom kernel patches I did to implement named network namespaces or current
kernels. I have to check if the quagga MPLS patches apply cleanly, they almost
did a while ago. I am now cleaning some stuff and I want to publish some code or
git tree in a week or two. At some point I had a test network with BGP feeding
the VPNV4 prefixes into my kernel, with LDP working, the only thing I needed to
have a full working VPN setup was PHP. But it was all a bit ad-hoc.
