</span>[SL] I don't know if it's possible for Mininet to set up VXLAN; that's a<br>
question best asked on a Mininet-related forum.<br>
<br>
As for whether it can be done on a single host, I suppose if you were to<br>
use 2 separate bridges for physical connectivity along with 2 separate<br>
bridges for the tunnels, it might work. I've never tried it, though, so<br>
this is just conjecture.<br>
