on a regular switch, each device on the peering LAN will be able to 
communicate with every other device on the peering LAN. There's no 
special configuration required to make this work.

If the switch is forwarding traffic from Amazon to Google, then the 
switch won't forward that traffic to e.g. Microsoft.

I.e. for a regular switch, you create a single VLAN and everything will 
automatically work the right sort of way.

If you're planning to build an SDN based layer 2 network (e.g. openflow, 
etc), then it might be different and there may be a requirement to 
program the switch with an adjacency / flow path for each potential 
src/dst combo (i'm not very clued up on openflow, so it might be simpler 
than this).
