Buying IP Bandwidth Across a Peering Exchange

I have seen this work well when the exchange allows more than one MAC address to be presented at layer2. This way you can have two separate sub interfaces presented, one for peering and one for your private cross connect/transit. That way the routing all stays clean and manageable. It's still a little messy, but is a much better solution than getting peering and transit over a single layer3 interface.

I know a couple networks that offer to sell transit over exchanges that permit it, but require that you take a private VLAN on the exchange.

Some exchanges offer private VLANs, others don't.
