I believe you have misunderstood Equinix's policy. I believe the
generally-applied policy is that you may not have multiple MAC addresses on the
same physical port, which typically means that you can't easily peer using
multiple ASes directly on the exchange switch fabric.
If you believe that this doesn't answer your question, please quote the Equinix
language that you're looking at, so we can help you better.
