Hilarious. Btw, is this multiple vNIC scenario based on real world experience? I am scared of more than 1 vNIC in a large scale deployment due to complexities in routing at the host level and further upstream.
There may be corner cases the require a different set of reachable vectors for a vm but there are many ways to provide that without more vNICs. Not completely opposed to the idea, but when I see scenarios discussing VMs with 5 vNICs I think the IETF may be off course here. There is a lot of rope, it's our choice to make a raft or a noose.
