[dev] FRR, NVO3, VNC, .. what happens underneath?

[Raymond Burkholder]

Hello,

I have a network virtualisation scenario, and I think FRR might be a part of it, but I am not sure.

I have taken a look at https://frrouting.org/user-guide/VNC-and-VNC_002dGW.html, and taken a quick skim of the NVO3 stuff.

The NVO3 stuff references a bunch of possibilities.  The FRR site provides command descriptions and a few examples.

The bit missing from the FRR site is what happens underneath?  What is actually used for encapsulation?  How does FRR interact with the encapsulation layer?   There was a one word reference to OpenFlow, but what is the glue that ties FRR, VNC, and the underpinnings together, particularly in a Linux environment?

Are there any presentations, blog entries, black-magic or dark-art places describing example scenarios?  Or is it really just that simple?

An additional search problem is that VNC refers to screen virtualisation, so search parameters become delicate.
