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 p=
hysical port, which typically means that you can't easily peer using multipl=
e ASes directly on the exchange switch fabric.=20
If you believe that this doesn't answer your question, please quote the Equi=
nix language that you're looking at, so we can help you better.=20
