[SL] I don't know if it's possible for Mininet to set up VXLAN; that's a
question best asked on a Mininet-related forum.

As for whether it can be done on a single host, I suppose if you were to
use 2 separate bridges for physical connectivity along with 2 separate
bridges for the tunnels, it might work. I've never tried it, though, so
this is just conjecture.
