Looking over it.. .and I don't know how I missed your last sentence there.
The RFC was drafted by engineers employed at Cisco, Arista, Broadcom,
RedHat, Vmware, and Citrix. I'm pretty sure that this is what the VPC's use
from how the Amazon sales engineers explained it. This is also how I got
the impression that they invented it, but what was said was actually that
"we had to write our own code for a custom solution".
