Hi Daniele,

VRF is different from network namespaces.

I have collected some materials about the VRF implementation of Linux:
- https://schd.ws/hosted_files/ossna2017/fe/vrf-tutorial-oss.pdf
(Slides introducing VRF)
- https://cumulusnetworks.com/blog/vrf-for-linux/ (Article describing
the differences among VRF, ip rule, and namespace)
Hope they help.

Best regards,
