Do we have some sort of beginner's introduction to Linux VRF somewhere?
What they are? How to use them?

Currently the concept simply doesn't fit into my mental model of networking...

We've actually talked about maybe possibly using VRF's in Android (for
our multi network support)...
but no-one on our team has the faintest idea about how they work...
(and there's rumours that they don't work with ipv6 link local)
